At Fishtown Medicine, we believe in building deep, ongoing relationships with our patients. Our founder, Ashvin Vijayakumar MD, or Dr. Ash for short, is a board-certified internal medicine physician with over a decade of experience in preventive care, hospital medicine, and healthcare innovation. He started Fishtown Medicine to provide the kind of care that traditional systems often miss: proactive, personalized, and focused on building long-term resilience.

Our care begins with a simple text and grows into a long-term partnership. We prioritize spending time with our patients, so you'll never feel rushed or reduced to a number. Instead, you'll be met with curiosity, context, and a plan that actually fits your life.

Dr. Ash is not just managing diagnoses — he's helping you build clarity, capacity, and long-term resilience.

Dr. Ash completed his internal medicine residency at AtlantiCare and a fellowship in value-based care leadership through Mount Sinai Health System. He has also held leadership roles in executive health, worksite clinics, hospital medicine, and virtual-first care models.

To stay current, Dr. Ash engages in weekly research review and continuing medical education (CME) from top medical journals and databases, including Journal of the American Medical Association, Nature, UpToDate, Journal of the American College of Cardiology, and influential podcasts and audiobooks. This ongoing study ensures that every recommendation is grounded in the latest science, not trends or guesswork.

When he's not in the clinic, Dr. Ash enjoys spending time with his family and two cats in Fishtown. He also loves biking, hiking, and camping, which reflects the balance, movement, and vitality he helps his patients build into their own lives.
