Susannah is a board-certified Adult Nurse Practitioner specializing in Adult Holistic and Functional Medicine.

Susannah Kerwin is an Advanced Practice Nurse Practitioner trained in functional medicine by the Institute for Functional Medicine. She holds degrees from the University of San Francisco and New York University and has been helping patients define and realize their best health for more than twenty years. Susannah started Tendwell after seeing first-hand how traditional medical practices shortchange patients by focusing on simple protocols and algorithms designed to maximize throughput and revenue, rather than taking the time to assess the whole person and to dive deeply into the root causes of dysfunction.

At Tendwell, Susannah uses cutting edge functional medicine techniques with her patients to not only address root causes, but to optimize health, all while keeping patients at the center and working collaboratively. Tendwell patients access advanced genetic, hormone and other testing to pinpoint issues often overlooked in traditional medical practices. In terms of treatment modalities: Susannah prioritizes nutritional and other non-pharmaceutical approaches and considers her patients as whole persons, not just lists of symptoms to be plugged into treatment algorithms. The results speak for themselves. Tendwell patients consistently rate themselves healthier, happier and more satisfied.

Prior to forming Tendwell. Ms. Kerwin lived and practiced in San Francisco, New York City, and overseas, including a year in China, where she spent time exploring Chinese traditional medicine. In her free time, Susannah loves to hang out with her kids. She enjoys travel & exploring new places. She is also an avid runner & Pilates enthusiast.
