Bio

Raised by his Italian grandparents in the steel towns of Western Pennsylvania, Dr. Antonis decided to pursue a career in medicine after receiving some advice from his high school guidance counselor. “She told me, ‘Nobody from this area ever becomes a doctor,’ and I wanted to prove her wrong,” he says. He went on to become the first in his family to go to college and the first to practice medicine.

Dr. Antonis earned a BA from Washington and Jefferson College in Washington, PA, and a medical degree from Chicago College of Osteopathic Medicine at Midwestern University in Downers Grove, IL. He completed a residency in emergency medicine at Advocate Christ Hospital and Medical Center in Chicago. For the next 13 years, he was an emergency department (ED) physician, serving as Associate Chief of Service at MedStar Georgetown University Hospital and ED chair at MedStar Southern Maryland Hospital Center. He also served as local medical director for the Washington, DC, Rock ‘n Roll Marathon for three years.

A life-long love of sports and a desire to expand his horizons led Dr. Antonis to pursue a specialty in sports medicine. He completed a fellowship at MedStar Georgetown University Hospital in 2018.

Dr. Antonis is a registered diagnostic medical sonographer with a special interest in ultrasound point-of-care exams and ultrasound-guided procedures, including platelet-rich plasma and newer biologic agents, to augment healing. He advocates shared decision-making with his patients to come up with a care plan that is both personalized and evidence-based. His great joy is to see patients return to previous levels of function – whether running a marathon or simply completing activities of daily living.

Dr. Antonis and his wife, a physical therapist, live in Alexandria. They enjoy hiking, running and watching baseball together. They will soon reach their goal to see games at every major league ballpark in the country.
