About

At Feltheimer Comprehensive Medical Care, Dr. Seth Feltheimer brings more than four decades of internal medicine experience to a private Park Avenue practice. He spent the majority of his career at Columbia University Medical Center as an Associate Clinical Professor of Medicine and Associate Attending Physician. That depth of academic and clinical experience now informs every aspect of this concierge practice. The practice accepts a carefully selected number of patients. Every call and every visit goes directly to Dr. Feltheimer, with no intermediaries, no nurse triage line, and no rotating providers. He offers same-day and next-day appointments, extended time for each visit, and consistent oversight of specialist referrals, test results, hospital coordination, and second opinions. Annual comprehensive evaluations and wellness planning keep care proactive rather than reactive.
