Quality Drive Away

"Our experience with GMS has by far been the best PEO we have partnered with. Everyone I've worked with at GMS has been very helpful and accommodating to our needs. Our dedicated HR account manager is always available when I need her."

FedEx Contractor

"Everything is under one roof when you partner with GMS. Whenever I have a question or concern, I know exactly who to call, as there's only one point of contact. There's no more 1-800 number. GMS is a company that can help you and your business be more competitive. I honestly can't think of a reason not to partner with GMS."

Health Care Organization

"Our experience with the payroll managers and payroll processing services has been fantastic. We've been extremely pleased. GMS has been an invaluable resource. In addition, GMS assisted in implementing the Drug-Free Workplace and PDP programs. Without GMS, we would have never accomplished our goals. In short, our partnership with GMS and its staff has been a rewarding experience."

"Having GMS administer our payroll, healthcare benefits, workers' compensation, and assisting with human resources management has enabled us to focus our own resources on our core business of making quality aluminum extrusions. The contacts that I use at GMS are knowledgeable, professional, and provide accurate information in a timely manner."

Therapy In Motion

"I love GMS, and they are easy to work with when you see just how great the service is. I always tell people that someone buys why you make something, not what you make. GMS provides turn-key support to the major functions of a business, all while saving the client's money."
