HR Companies & HR Consultants in Brentwood, TN

Dominion Payroll is a workforce management company that combines payroll, human resources, benefits, timekeeping and talent tools for employers. It says it has more than 5,000 clients, ranging from businesses with about five employees to organizations with several thousand. The company works in all 50 states and pays over 140,000 workers each week. Its Middle Tennessee office in Brentwood serves employers around Nashville, including those in Spring Hill. The company is headquartered in Richmond, Virginia.

HR Support Options

Buyers can choose how much HR help they need, from occasional advice to an ongoing outside partner. DP Assist is an on-call advisory service for everyday personnel issues such as leave requests, disciplinary steps and terminations. DP Boost HR is a larger package that adds compliance reviews, a custom employee handbook, salary benchmarking and help managing leaves of absence.

Employers that want ongoing expert attention without a full-time HR hire can use the fractional HR offering, which assigns a dedicated advisor who gets to know the business.

Payroll, Time and Benefits

The core of the service is a connected system in which hours, pay and tax filings feed into one another automatically. Its main services include:

• Payroll runs with direct deposit, printed checks and pay stubs
• Federal, state and local payroll tax calculation and filing
• Time tracking through physical clocks, biometric readers, mobile check-in and scheduling tools
• Payroll data mapped automatically to the client's general ledger
• 401(k) contributions and retirement reporting synced with payroll
• Benefits enrollment, administration and reconciliation, carrier connections, ACA reporting, and COBRA, HSA and FSA administration

Hiring and Retention

For recruiting, clients get applicant tracking that posts jobs to many job boards, screening questionnaires and interview scheduling. Electronic onboarding covers new-hire paperwork, I-9 and E-Verify steps, as well as employee departures. Background checks, including criminal, driving and credit checks, are handled through a national screening partner.

For retention, Dominion offers analytics that flag employees who may be likely to leave, the UCM tool for viewing pay, recognition and engagement together, a learning management system, performance reviews, on-demand pay through ZayZoon, expense management, and a giving and volunteering platform.

All of these services run on isolved, a single sign-on platform that Dominion sets up for each client. Its support team is staffed by people rather than automated systems. Clients can also get a free consultation that reviews where their payroll and HR processes are slowing them down.

Background and Focus

Dominion has operated for more than two decades. The company says its founding goal was to offer an alternative to traditional payroll firms, with service as its main selling point. Its leadership team is headed by CEO Dennis Gallagher. The company lists logistics, education, healthcare, nonprofits, hospitality and wellness among the industries it serves.

It also partners with CPA firms, franchises, banks and private equity groups. Community involvement is one of its seven stated values, and staff volunteer and support nonprofits.

Exodus HR Group is an outsourced HR, payroll and workplace safety provider with offices in Brentwood, Tennessee and Durant, Oklahoma. The firm works with small and mid-sized employers that are expanding and want a single partner to take over the people-related administration that tends to pull owners and managers away from running the business. Its Tennessee office in the Maryland Way corridor of Brentwood is the location nearest to Smyrna and the Rutherford County area.

Services offered

The company bundles several functions that are designed to operate together rather than as separate vendors. Buyers comparing providers can expect the following areas of support:

• Payroll processing and payroll tax handling, with the firm citing a 98 percent accuracy record
• Human resources support covering onboarding, written policies and regulatory compliance
• Administration of employee benefit programs and the compliance tasks attached to them
• Benefit, wellness and retirement plan options for staff
• Workplace safety programs, safety training and liability reduction
• Recruiting and team-building assistance to help clients hire and keep strong employees

Technology is a central part of the offering. Exodus HR Group runs its services on UKG Ready, a human resources information system that clients use to manage the full employee lifecycle, from the hiring stage through to separation or retirement. HR guidance is delivered by certified HR professionals, which matters for employers that lack in-house expertise on policy writing or compliance questions.

How the firm works with clients

A recurring theme in how the company describes itself is accessibility. It states that phone calls are picked up by staff members instead of automated answering systems, and it positions its service team as people who learn each client's operation.

The firm also does not require clients to sign long-term or binding agreements, taking the view that a client relationship should be kept through performance. Prospective clients can complete a short questionnaire on the website that suggests which plan suits their priorities, and published plan tiers allow businesses to compare levels of service before engaging.

The company says it tailors its work to the culture and goals of each organization, aiming to give employers structured, compliant and safe people systems that support productivity. It presents recruiting help as a way for leaders to spend less time screening resumes and more time on strategy.

Industries and background

Exodus HR Group highlights experience with several sectors, including:

• Construction
• Energy
• Churches and faith-based organizations
• Nonprofit organizations

The safety and risk management emphasis makes the firm a reasonable fit for employers in field-based or higher-hazard industries, while its attention to churches and nonprofits suggests familiarity with the particular administrative needs of mission-driven employers. With operations in both Tennessee and Oklahoma, the company serves businesses beyond a single local market.

For Middle Tennessee buyers, it offers a combination of payroll, HR, benefits and safety services under one roof, backed by a recognized HRIS platform and a no-contract approach that lowers the commitment involved in trying a new provider.

Headquartered in Texas but recruiting nationwide, Frontline Source Group helps employers fill professional roles and leadership seats. For organizations around Spring Hill, the nearest office is in Brentwood, Tennessee, where the local team supports companies in Brentwood, Franklin and across Middle Tennessee. Buyers comparing HR providers should understand the firm's scope. It is built for organizations that want outside support in locating and hiring talent. It does not run payroll or take on routine human resources administration.

Services and engagement models

Clients choose the depth of partnership that suits each opening. The lightest option is a subscription that sends new candidate profiles every night for every active requisition. The most hands-on option is a fully retained executive search. The main services are:

• Short-term and contract workers for temporary needs or specific projects
• Contract-to-hire arrangements that can turn into permanent jobs
• Direct-hire recruiting for permanent roles
• Leadership searches priced on a contingent, engaged or retained model
• Candidate-sourcing subscriptions, currently open only to existing clients
• Fractional executives, including part-time CFOs
• Skills testing, a showcase of available talent and vendor-management support

HR recruiting and other specialties

Human resources hiring is one of the firm's main focuses. In Brentwood, recruiters place generalists, HR managers, HR administrators and recruiting coordinators. They also fill specialist roles in employee relations, compliance and risk, and learning and development. At the senior level, the executive practice recruits benefits managers, HR directors and chief human resources officers.

Beyond HR, the firm covers more than a dozen other fields: finance and accounting, legal, IT and cybersecurity, and office and executive support. It also recruits in healthcare and pharmacy, dental, engineering, oil and gas, data centers, marketing, life sciences and C-suite leadership.

How it works with clients

Every search is run by a recruiter who specializes in the field rather than by software alone. These recruiters use an in-house AI matching platform that includes virtual recruiter personas. Job seekers are seen by appointment only, so offices do not accept walk-ins. Pricing is published openly rather than shared only after an inquiry.

Direct hires are backed by a five-year warranty, which the firm sets against the 90-day guarantee most rivals offer. Written terms explain how the warranty applies if a placed employee leaves during that period.

Background and credentials

Founder Bill Kasko launched the company in Dallas in 2004. He continues to serve as President and CEO, and Dallas is still home to its headquarters. The business now runs more than 32 offices in multiple states. Two are in Tennessee, one in Nashville and one in Brentwood.

Others serve Texas and Georgia, along with Arizona, Illinois, Colorado, Oklahoma and additional states. According to internal figures, the firm has completed more than 5,619 placements. Those figures also show that a year after hiring, 98.94 percent of executives it placed were still in the role or had been promoted.

Forbes has listed the firm among top professional recruiting firms each year from 2018 through 2026 and added an executive recruiting ranking in 2026. ClearlyRated has awarded it nine Best of Staffing distinctions, which are based on satisfaction scores from both client companies and candidates, and has also granted it Diamond-level recognition.

The company has earned a spot on the Inc. 5000 as well. It belongs to the American Staffing Association, the national trade group for the industry. On Trustpilot it holds a perfect 5.0 score from 679 reviews.

LBMC Employment Partners is a human resources services company headquartered in Brentwood, just south of Nashville. It is part of the LBMC Family of Companies, a Tennessee professional services group known for accounting, tax, advisory and technology work. Founded in 1998, the HR firm works as a professional employer organization (PEO), an HR outsourcing provider, a payroll service bureau and a benefits broker. It helps employers handle the people side of running a business.

Who They Serve

The company works with organizations ranging from about five employees up to roughly 1,500, across many industries. Most clients are small and mid-sized businesses in Tennessee and the wider Southeast.

That makes the firm a fit for a growing company that does not yet have a full internal HR department, as well as for a larger employer that wants to hand off specific tasks such as payroll or benefits administration.

Through an affinity partnership announced in 2023 with the Tennessee Chamber of Commerce and Industry and the Tennessee Manufacturers Association, the firm also offers its HR services to members of those groups, including the state's manufacturers.

Services Offered

Buyers can choose a full co-employment arrangement or pick individual services. Its main offerings are:

• Professional employer organization (PEO) services, in which HR duties, payroll, benefits and compliance are shared under a co-employment model
• HR outsourcing for companies that want support with hiring, onboarding, training and risk management without co-employment
• Payroll processing and payroll tax administration
• Human resource consulting
• Employee benefits brokerage and program design
• Affordable Care Act (ACA) compliance consulting

Because it belongs to the larger LBMC group, clients can also use related resources from sister practices. These include recruiting and staffing, employee benefit plan audits, tax and cybersecurity services, so a company can coordinate its HR, financial and compliance needs within one group of firms.

How They Work With Clients

The firm's tagline, which puts a client's people first, reflects its focus on the workforce rather than on paperwork alone. Its team includes HR business partners, an HR director, and implementation and support staff who move new clients onto its platform and help them afterward. That setup lets employers have dedicated HR contacts while keeping control of daily business decisions. Companies can start with one service, such as payroll, and add PEO or consulting support as they grow.

Background and Recognition

LBMC Employment Partners has offices in the Nashville area (Brentwood), Knoxville and Chattanooga, so it can serve employers across much of Tennessee. In 2023 the firm marked 25 years in business. That same year, Mployer Advisor named it a Top Employee Benefits Consultant for the third year in a row.

Mployer Advisor's program looks at industry experience, company size and client reviews. For buyers comparing HR providers around Nashville, its main strengths are its long local history, its range of PEO, outsourcing, payroll and benefits services, and the backing of a large regional professional services group.

Lyons HR is a professional employer organization that now operates under the OneDigital | Resourcing Edge banner. The brand changed after it joined Resourcing Edge, but the company says its client-facing staff are the same people as before and that its HR operation is still rooted in Alabama. For buyers in and around Brentwood, Tennessee, it offers an outsourced back-office model: a PEO takes on much of the employer administration that small and mid-sized organizations would otherwise do in-house.

Services offered

Its offerings are grouped into a handful of practice areas that together cover most of the employment lifecycle:

• Payroll processing combined with day-to-day HR support
• Regulatory and employment-law compliance help
• Employee benefits programs for client workforces
• Workers' compensation coverage and workplace risk management
• Recruiting help for filling open positions

The website also publishes separate terms for an ASO (administrative services only) arrangement. That suggests clients may be able to choose between a full co-employment PEO relationship and a lighter administrative package, depending on how much responsibility they want to hand over.

How clients work with the firm

Clients and their staff use PrismONE, an online platform with separate employee and manager logins. Employees can check their own information, and managers handle tasks for the people who report to them. Former clients who signed up before the move to the new platform still have access to the earlier login and enrollment portal.

Companies considering a PEO can ask for a quote through an inquiry form, which asks for headcount (with tiers from one to twenty workers up to more than fifty), the state where the business is located, and the reason for its interest in a PEO. The form accepts businesses from any U.S. state.

Background and locations

Lyons HR started as an independent Alabama PEO before becoming part of Resourcing Edge, which in turn belongs to the OneDigital organization. Third-party business directories place its headquarters in northern Alabama and list several branch offices, including locations in Brentwood and Knoxville, Tennessee. Directory listings also report that the University of North Alabama named its Human Resources MBA program after Lyons HR, which reflects the firm's long-standing ties to the HR profession in the region.

For organizations comparing HR providers, the main points are the combination of an established regional team with the larger resources of a national PEO group, a single provider for payroll, benefits, compliance, insurance-related risk services and hiring support, and a self-service technology platform for both workers and supervisors. It suits employers that would rather outsource the administrative side of employment than build a full internal HR department.

Overview

Mosaic Consulting Group is a consultancy based in Nashville that helps employers get more out of UKG human capital management software for HR, payroll and workforce management. Vicki Hill founded the firm in 2011 after working with UKG both as a consultant and as a customer.

It now has a staff of more than 250 and says it has served over 1,000 clients. UKG named Mosaic its partner of the year for 2025. More recently the company added an SAP Cloud ERP practice, so one firm can now handle both a client's finance and operations platform and its HR technology.

Buyers comparing HR consultants should know that Mosaic is a technology partner, not a general HR advisory firm. Its work centers on UKG Pro, UKG Pro Workforce Management, UKG TeleStaff and UKG Ready. It supports clients through the whole life of these systems, from planning and first deployment to long-term administration.

Services

The firm sorts its work into several practice areas:

• Implementation: full UKG launches, single-module activations, moves from UKG Central to Pro WFM, and client-side advisors who represent the customer during a vendor-led rollout
• Managed services: outsourced payroll processing, emergency and contingency payroll cover when internal staff leave suddenly, HR outsourcing and culture consulting
• Premier services: a monthly block of hours with a dedicated UKG specialist. The specialist covers security roles, workflows, general ledger questions, open enrollment, year-end preparation, data audits and support during mergers
• Strategy: strategic assessments, optimization planning, change management and AI strategy consulting
• Technical: integrations, data conversion, BI reporting and the firm's own Mosaic Insights analytics tool for UKG Pro, which tracks turnover, recruiting and DE&I metrics
• Training: customized UKG instruction, plus running learning management systems and building LMS courses

How they work

Mosaic describes its approach as collaborative. Consultants first learn a client's goals and processes, then build solutions around how HR, payroll and finance staff really operate day to day rather than around default software settings. Many engagements become ongoing relationships instead of one-time projects.

Testimonials on its site describe the team running payroll after a payroll manager quit without notice, and making training videos, job aids and FAQs during an implementation. The company also points buyers to independent reviews on Raven Intelligence, where it reports an average of 5 out of 5 and a partner satisfaction score of 9.78 out of 10.

Its UKG Ready offering is for small and mid-sized businesses that want help after go-live. That help includes ongoing tuning, outsourced HR and payroll support, and extra staffing capacity. Premier services suit organizations already live on UKG that have lost in-house knowledge through turnover, want a fresh review of their setup, or need help choosing priorities.

Industries and background

Mosaic lists experience in healthcare, manufacturing, retail, financial services, government, nonprofits, professional and technology firms, restaurants and hospitality, and logistics and distribution. It has grown through acquisitions: Westward in 2021, then in 2024 the UKG workforce management unit of Agilea Solutions, D&E and Project Genetics. Mike Maiolo leads the company as CEO and Executive Chair. Krystyn Sadler heads the UKG side and Noel Fagan the SAP side, and founder Vicki Hill still sits on the board.

Principle HR Solutions & Consulting, LLC is a fractional human resources firm based in Brentwood, Tennessee, just south of Nashville. The company works with small and midsize employers that either lack a dedicated HR function altogether or have an internal HR staff stretched too thin to keep up.

Rather than asking clients to hire a full-time HR leader, the firm supplies senior-level guidance and a supporting team on a part-time, as-needed basis, giving owners access to experienced practitioners while keeping fixed costs down. It has recently expanded its offering to include payroll services.

Services

The firm describes its work as full-scope HR support that is adjusted to each client's growth stage, organizational structure and strategic priorities. Its main areas of practice include:

• Compliance and risk mitigation, including HR audits, workplace investigations and keeping policies current as employment regulations change
• Employee relations and coaching, covering performance management, improvement plans, difficult conversations and engagement initiatives
• Recruiting and onboarding, from sourcing candidates to structured onboarding and offboarding procedures that help new staff become productive sooner
• Strategic HR, such as succession planning and compensation analysis tied to business objectives
• Training and development, delivered through individual coaching and structured programs for managers and employees
• Payroll services, a newer addition to the lineup

How They Work With Clients

Engagements follow a three-stage process. A prospective client first schedules an introductory discovery call to talk through its people challenges and goals. The firm then carries out an HR needs assessment, reviewing the organization's workforce, procedures and exposure to risk, and uses the findings to build a tailored plan.

In the final stage the plan is put into action, with the consulting team providing continuing support afterward. The company stresses that it does not sell standardized packages; each arrangement is shaped around the client's culture, staff and objectives, and services can scale up or down as needs evolve.

A relationship-based philosophy runs through the firm's approach. Consultants invest time in learning how a client's team and culture function before recommending changes, and the company positions itself as an embedded partner instead of an outside vendor.

Its stated aim is to help employers move from reacting to personnel problems toward preventing them, with the goal of lowering turnover, reducing legal exposure and improving productivity. Clients get a team-based model, so an owner has several HR specialists to draw on rather than relying on a single individual.

Team and Background

The firm is led by President Jeff Batts and Senior Vice President Shelli Meador. The broader team includes HR Business Partner Chandler Batts and HR Project Specialists Pam Coggin and Ashley Farmer, who together bring many years of collective human resources experience.

Client testimonials published on the company's site come from a range of employers, including a young, fast-growing retail and dance-fitness business, and reviewers point to the team's consultative style, its practice of educating owners along the way and its effort to balance the interests of employers and employees.

For buyers comparing HR providers in the Nashville area, Principle HR Solutions is best suited to growing companies that want ongoing, customized HR guidance and a named team of practitioners, without taking on the cost of an in-house department.

The HR Group, LLC is a human resources firm located in Brentwood, Tennessee. Directory listings place its office on Maryland Way, inside the Maryland Farms business district just south of Nashville. Its client base is centered on employers in the greater Nashville area, and in particular on small and mid-sized businesses that would rather rely on outside specialists for human resources and employee benefits than build out those functions entirely on their own.

Who the Firm Serves

Companies of this size often operate without a full internal HR department, or with a small team that has to cover hiring, benefits, policy and regulatory matters all at once. The HR Group's focus on this segment means its work is aimed at organizations that need dependable HR capability without carrying the full cost and complexity of staffing it internally. Its suburban Nashville base also ties the firm closely to the regional business community it serves.

Services

Third-party business profiles describe the firm as operating in two linked areas: employee benefits on one side and broader human resources support on the other. Bringing these together allows a single outside partner to address both how a company's workforce is managed and how its benefits programs are structured and run. The services attributed to the company include:

• Benefits brokerage and products, helping employers source and arrange coverage for their workforce
• HR management consulting on how the people side of a business is organized and run
• Outsourced benefits administration, taking day-to-day management of benefits programs off the employer's plate
• Strategic HR guidance for longer-range workforce planning and decision-making
• Compliance audits that review existing HR practices against applicable requirements
• Leadership training intended to strengthen managers and supervisors
• Tailored HR solutions designed around the needs of each individual client

Taken together, this mix covers both transactional work, such as administering benefits, and advisory work, such as audits, strategy and training. The emphasis on customized solutions suggests the firm adapts its engagements to each employer rather than offering a single fixed package.

Background

Industry databases record a Brentwood company named The HR Group as having been founded in 1996, which would give it a history of well over two decades in the Nashville market. The same sources indicate that the business was later acquired by Gallagher, while still listing it as active. Prospective clients should confirm directly with the firm how it is currently owned and branded, and whether that relationship shapes the range of services or products it can provide.

This profile draws solely on published third-party listings. Employers comparing HR consultants in the Nashville area are encouraged to contact the firm for specifics about its team, professional credentials, the industries it works with most often and the way it structures client engagements.
