About
At Exceptional Health, five physicians deliver concierge primary care from their Wellesley Hills, MA practice. Karen 'Kate' Isselbacher founded the practice in 2011 after two decades of primary care at Mount Auburn Hospital and Brigham and Women's Hospital. She built Exceptional Health on a clear belief: concierge medicine should be tailored to each individual patient.
The team includes Dr. Nancy Haff, Dr. Kevin Heaton, Dr. Christine Harrington, and Dr. Li Tso. Each physician brings deep academic credentials, with faculty appointments at Harvard Medical School spanning the group. The practice sits within the Mass General Brigham network and bills medical services through its parent company, Private Healthcare Group, LLC. Members reach their physician directly by phone, day or night. Same-day and next-day appointments, unlimited visits, extended appointment times, and telehealth through Patient Gateway, Zoom, and Doximity give patients consistent, unhurried access. On-site capabilities include phlebotomy, electrocardiograms, vaccinations, urinalysis, wound care, and women's preventive care. The practice also hosts health education seminars on topics such as weight management, diabetes care, and joint health.
