Philosophy of Care

As a physician and athlete, I enjoy being able to get to know my patients and become part of their team.  I try to learn what their goals are and help them get there, with a focus on maximizing their physical and mental health in the process.  I love helping patients get back to doing what they love, and hope that I can work with them to get them to train smarter and safer, improving performance and health in the process.


Kathryn E. Ackerman, MD, MPH is a sports medicine physician and endocrinologist and the medical director of the Female Athlete Program in the Sports Medicine Division at Boston Children's Hospital. Her interests include female athletes, rowing injuries, endocrinology, relative energy deficiency in sport (RED-S), optimizing performance and health in athletes with diabetes, exercise-associated hyponatremia, and exercise and bone health. Dr. Ackerman sees patients in Boston and Waltham.

Dr. Ackerman's interests in clinical care and education involve merging disciplines of sports medicine and endocrinology, while advancing the science and understanding of these interwoven specialties. Dr. Ackerman is a former national team lightweight rower, chair of the US Rowing Medical Commission, member of the World Rowing Medical Commission, and the course director for the Female Athlete Conference, held biennially at Boston Children's Hospital.
