The word “doctor” is derived from the latin docere, which means “to teach.” Dr. Libby is a life-long learner, teacher, and servant-leader. He graduated with a Bachelor of Science in Physics from the University of Massachusetts at Amherst, and soon found his calling teaching in a wide variety of settings—from working with underserved youth in after-school programs, to tutoring at elite private schools, to managing a laboratory of physics demonstrations for university lectures.

After a few years, Dr. Libby returned to school to pursue his Doctor of Osteopathic Medicine degree from the University of New England, where he served as a teaching assistant, tutor, volunteer, and leader in a number of student organizations. One of the most formative experiences was caring for farm workers in a mobile clinic, during the blueberry harvest in Maine—work that he has since reconnected to and continues with. His activities in school earned him several awards, including the Sauter Award for Graduate with Distinction: “For possessing those qualities the faculty would seek in their family physician.”

Dr. Libby went on to complete a residency in Family Medicine at the Tufts-affiliated Lawrence Family Medicine Residency, nationally known for being the first Teaching Health Center and training top family physicians and leaders. In residency, he received teaching awards from both the faculty and the junior residents.

Upon completion of training in 2015, Dr. Libby moved to Cape Cod to serve as a National Health Service Corps Scholar, providing primary care in a federally-designated shortage area. Over the past decade he has cared for people of all ages and from all walks of life. He is experienced in primary, preventive, and urgent care, management of complex chronic conditions, and office procedures such as skin biopsies and joint injections. As an Osteopathic physician, Dr. Libby can incorporate Osteopathic Manipulative Treatment for patients who are interested. He is currently pursuing further training in lifestyle medicine and functional medicine.

In addition to his clinical practice, Dr. Libby has held executive and director roles in community health centers on Cape Cod and other professional organizations, as well as in the health tech startup space. He is a Fellow of the American Academy of Family Physicians, serves as the Treasurer on the Board of the Massachusetts Academy of Family Physicians, and is an Instructor in Family Medicine and Community Health at UMass Chan Medical School. In 2017-2018 Dr. Libby completed a fellowship in Primary Care Leadership at the Harvard-affiliated Beth Israel Deaconess Medical Center in Boston, and in 2024 was among the first cohort of physicians in the country to earn a Certificate of Added Qualifications in Healthcare Administration, Leadership, and Management from the American Board of Family Medicine.

Outside of work, Dr. Libby enjoys cooking, hiking, camping, photography, and spending time with his three children and his partner, Kelly: a Licensed Mental Health Counselor with her own independent practice.
