About
At Mark Chien MD, a board-certified internist brings nearly two decades of Chicago medical experience to a small, relationship-driven concierge practice. Dr. Mark Chien has practiced in Chicago since 2006. He runs two office locations: one near Northwestern Memorial Hospital in the city, and one in Oak Brook. Dr. Chien keeps his practice intentionally small. Appointments run 30 to 60 minutes depending on complexity. He handles acute care, chronic disease management, wellness exams, and a range of in-office procedures including cortisone injections, IV hydration therapy, spirometry, and rapid testing. He holds a staff position at Northwestern Memorial Hospital and maintains long-standing relationships with specialists there. He also serves as a clinical instructor at Northwestern Feinberg School of Medicine. His goal is to manage as much of each patient's care in-office as possible and keep patients out of the emergency room.
