Dr. Jay Luthar MD Concierge Primary Care is a Boston-based integrative medicine practice designed around one foundational belief: that true healing begins with presence. Dr. Luthar — triple board-certified in Internal Medicine, Lifestyle Medicine, and Integrative Medicine, and trained in Mind-Body Medicine — intentionally limits his patient panel to deliver the kind of deep, unhurried, personalized care that modern medicine rarely allows. A faculty member at Harvard Medical School and staff physician at Brigham and Women's Hospital, Dr. Luthar combines the rigor of precision diagnostics with the depth of mind-body healing, East-West longevity science, and lifestyle transformation — building long-term health partnerships that treat the whole person, not just the diagnosis.
