An intelligent, thoughtful care provider, Dr. Sebastian Ruhs directs the Infectious Diseases Center of Excellence at Chase Brexton Health Care, as well as serves as the medical director for Chase Brexton's Mt. Vernon Center.

Dr. Ruhs completed medical school at Justus Liebig University in Giessen, Germany, earning an MD and PhD. He completed an Internal Medicine Residency at Norwalk Hospital in Norwalk, Connecticut followed by an Infectious Disease fellowship at Yale in New Haven, Connecticut. He joined Chase Brexton as an infectious disease physician in October 2013.

During his time at Chase Brexton, Dr. Ruhs has helped grow our hepatitis C treatment program across all our Centers. His work led to that program being a "bright spot" that attracted a visit from members of the Centers for Disease Control and Prevention. 

In addition, Dr. Ruhs possesses a passion for the education of providers about HIV medicine. He has been the medical lead in developing the HIV & Hepatitis rotation for Urban Health medical residents from Johns Hopkins, and has trained Chase Brexton providers in HIV care, assisting them toward American Academy of HIV Medicine (AAHIVM) certification.
