Client Success Stories

"I have been a Medical Practice Administrator for over 30 years and one of the best decisions I ever made was to contract with MMC for our HR and payroll needs! Being a control freak, I was more than a bit skeptical about making the decision to outsource, but after almost 9 years of partnering with MMC, I wonder how I ever did it on my own. Services and employees are top-notch and professional and as our practice grows so do our needs and they meet every one of them. Thank you, MMC."


"Our experience with MMC, Inc. has been a very positive one from the start and we’re grateful for all that you and your staff provide us…you should be proud of your entire staff’s competence and professionalism."


“Outsourcing our HR issues to MMC has been the best decision we could have made. Since moving to MMC we find that our HR problems have greatly diminished and the ones we still encounter get taken care of promptly with minimum fuss allowing us to concentrate on running our day to day business. We would strongly recommend them to anyone looking for a solution to their HR issues.”
