About this Location 

Free valet parking is available.

At our new O'Fallon location, we provide Family Medicine, Behavioral Health, as well as OB and Pediatric services to patients in partnership with St. Louis University Family Medicine Residency Program and St. Elizabeth's Hospital. Our office is accessible through the St. Elizabeth's Health Center entrance.

Our partnership with St. Elizabeth’s Hospital, St. Louis University School of Medicine and Scott Air Force Base enables us to serve and provide clinical care for patients of all ages, including the military community.

We take pride in our very diverse and unique medical group, as well as our full spectrum of medical care. As a staple of the community we serve, our clinic provides a full spectrum of medical care including care by family counselors and family practice physicians. When patients walk through our doors, they can rest assured that they have a team of healthcare advocates on their side.
