Alexander Christofis, DO
Family Medicine
Dr. Alexander Christofis is a board-certified family medicine physician providing comprehensive care to patients of all ages in Troy, Rochester, and the greater Metro Detroit area.
Originally from Romeo, Michigan, he earned his undergraduate degree from Grand Valley State University and his medical degree from Michigan State University College of Osteopathic Medicine. He completed his residency at Henry Ford Rochester Hospital (formerly Crittenton), where he served as Chief Resident in his final year.
Prior to opening Phase Medical Group, Dr. Christofis gained experience at Opdyke Medical in Pontiac, which helped shape his commitment to independent, community-based primary care.
He founded Phase Medical Group as an independent practice with the goal of delivering an exceptional patient experience. He believes primary care should be easy to reach and personal, with real conversations, clear plans, lasting relationships, and care that adapts as patients' needs change through every Phase of life.
Dr. Christofis was one of 26 family physicians named to Hour Detroit's 2026 Top Docs list, based on a peer-nomination survey of physicians across Wayne, Oakland, Macomb, Washtenaw, and Livingston counties.
Outside of medicine, Dr. Christofis enjoys spending time with his wife and their twin boys, lifting weights in his home gym, and staying active in the Metro Detroit community he grew up in and now serves.
