Germantown Health Center

I believe that team based collaborative care is the key to helping patients achieve their health goals. To that end, I strive to tailor my advice to each individual, involving patients in their health care decisions. We then employ a team approach to support those goals. My office staff, medical assistants, nurses, care coordinators, advanced practice partners act as a willing and eager cast to help patients succeed. Come see what a team approach can do for your health!
