Our Mission & Values:


The providers and staff of Concierge Medical Services would like to thank our patients for giving us the opportunity to build relationships, improve quality care, and enjoy invaluable time together as partners in health care since the opening of our practice in April, 2006. This journey has been possible only because of the relationships that have been established. At CMS there is a unique bond between patient, provider, staff, and families/caregivers often not found in traditional medical practices.

We believe that CMS offers: “Modern Medicine…Old Fashioned Values.”

Ira Z. Gerstman, M.D.

“Through Concierge Medical Services of Family Practice Associates of Upper Dublin, I have been able to relate to my patients as a traditional family physician. Our relationships have been enhanced with the ability to spend more time with each other. We can delve into life’s medical and social complexities which results in better and more comprehensive care. I feel rejuvenated and energized. My passion for family medicine and treating patients without the constraints posed by current insurance realities is back to where it was when I first started practicing medicine.” Read more>
