Care you can trust

Your health and safety are always our top priority. Here's what you can expect from an in-office visit:

  • Face masks required for everyone, regardless of symptoms
  • Frequent disinfecting and cleaning of public spaces and exam rooms, including after every clinical visit
  • Staggered appointments to minimize people in a given area
  • Screening all patients and visitors for symptoms upon arrival
  • Physical distancing with floor markers and reconfigured waiting areas
  • Sanitizing stations throughout the facility

Building a relationship with a primary care provider is a great first step to a healthy life. Our MedStar Medical Group physicians have been treating patients from their 19th Street practice for years. Now at MedStar Health at Lafayette Centre, we are pleased to offer the same great care to this community. With on-site access to MedStar Health’s expert specialists, as well as laboratory and imaging services, we are able to provide you comprehensive, seamless care.

Our primary care specialists include both internal medicine and family medicine providers, and we offer an extensive range of services for adults, children, and infants. While our family medicine providers care for patients of all ages, our internal medicine providers primarily care for patients age 18 or older, as well as adolescents.
