Our Difference: Our Founders

Our Difference

With a clear focus on practice efficiency, sustainable billing methods, and a patient-centered approach, Maxx Medical is your clear choice for RCM.

Our client service teams represent the industry’s best practices, led by a highly seasoned and deeply credentialed senior management team that clears the path to success.

Our founder, Sheila Petrequin, has been at the forefront of Revenue Cycle Management for over 35 years. She is one of only a handful of CHBME (Certified Healthcare Billing Manager Executive) associates in Ohio. This certification is a distinction through HBMA, an organization of over 1,500 members designed specifically for RCM companies.

Sheila’s professional experience reflects her personality—progressive growth with a twist of fun! Before founding Maxx Medical, in her 40-year career she has been:

  • Chief Operating Officer of a 400-physician and 150-employee medical practice
  • A consultant, traveling from coast to coast installing, implementing, guiding, and training physician practice employees on the nuances of new Physician’s Account Receivable software
  • Manager of a local RCM for 13 years

She attended high school and college in southern Ohio, and her career began as a supervisor at the Springboro Clinic in Springboro, Ohio.

Sheila has built a client service team around her that delivers excellence and personalized support, crafted to your practice’s needs and challenges.

In 2020 Sheila partnered with Adam Middleton of Healthcare Advisory Network to broaden Maxx Medical’s reach into consulting and secure the long-term vision of independent practice management services.

When you visit Maxx Medical, you will see Sheila’s “twist of fun” come to life with her purple office and unique decorations, all contributing to a fun and productive work environment!
