Foundation for Success

Group Management Services opened for business in January, 1996. Mike Kahoe founded GMS, building upon his experience in high-profile Human Resources positions.

Every year since 1996, GMS has grown. Mike and his team have built a thriving PEO that continues to grow.

Today, GMS:

  • Has more than 20,000 employees
  • Partners with more than 1,000 companies
  • Is one of the largest employers in Ohio
  • Produces more than $40 million in revenue annually
  • Our services work collaboratively for you.  We bundle your services together for greater efficiency, improved quality, and reduced costs.

Why GMS? 

More than 90% of our clients remain with GMS year after year. Why?

We’ve been providing the best services at the lowest costs to Ohio small businesses since 1996 and that service now extends across the country. Our company has grown every year since then, and we are now one of the largest employers in the State of Ohio. We have more than 20,000 employees at more than 1,000 companies.

We are a stable, reliable company that you can trust to be there for you and your company in whatever way you need. We succeed when your business succeeds; we’re committed to doing everything we can to help your company achieve success.

How We Save You Time & Money

At GMS, we believe in creating solid partnerships where we save companies money and give employees the best benefits. We’re able to:

  • Secure competitive rates for insurance coverage
  • Simplify and automate payroll
  • Manage necessary safety and training programs
  • Reduce paperwork and record keeping
  • Assume tax liability and mitigate risks
  • Assume all costs and fiduciary responsibility of managing a 401k

When GMS handles all of your administrative and HR functions, you reduce the cost associated with having employees and you have more time to do what you do best—run your business.

GMS Makes Business Administration:


We consolidate all HR functions into one cohesive plan. You don’t need to have multiple vendors providing you different services, with the hassles of trying to coordinate these services. With GMS, it is one-stop shopping for your administrative needs.


GMS assumes tax liability for your company and manages risk. Whatever comes your way—workers’ compensation, safety inspections, unemployment claims—GMS has you covered. GMS also offers training for OSHA compliance, safety regulations, and implementing drug-free policies.


When you’re spending time sorting out taxes, or sifting through new legal regulations, or managing a 401(k) plan, you’re not spending time searching out new business opportunities, growing your client base, or helping your employees realize their full potential. Your business is stronger when you have more time to devote to it. And you can have peace of mind knowing that you are backed by the full weight of a 14,000 employer company.

Employment Practices Liability Insurance (EPLI)

It pays to be protected. Which is why our Employment Practices Liability Insurance (EPLI) policy covers all of our customers. 

  • There has been a 2,000% increase in employee litigation in the since 2007
  • $300,000 was the Average settlement per claim
  • $50,000 was the average litigation per case
  • Wrongful termination claims are up 260%

The question for any organization is no longer whether it will face an employment practices claim, but rather how much such a claim will cost them - not only in terms of money, but also "soft" costs like damage to reputation and brand image, company morale and the business owner's time and peace of mind.

EPLI is a key component of a comprehensive loss control strategy that protects you against claims (including lawsuits and administrative proceedings such as EEOC charges) filed by employees, former employees, and applicants for employment alleging discrimination (such as on the basis of race, age, ethnicity, religion, gender, and disability), harassment (such as sexual harassment), wrongful termination, illegal retaliation, and wrongful failure to hire.
