Southern Maine Integrative Health

Patrick Mulcahy, D.D.S., D.O.

Dr. Mulcahy received his bachelor's degree in Chemistry from Manhattan College in Riverdale, New York. He then went on to complete his dental training at New York University, College of Dentistry. After practicing Dentistry for eight years, he decided to pursue a medical degree and enrolled at Kirksville College of Osteopathic Medicine in Kirksville, MO. Upon completion of an internship at Saint Vincent's Hospital in Worcester, MA and then a Family Practice Residency at the University of New England, College of Osteopathic Medicine in Biddeford, ME, he then fulfilled his public health service commitment with the National Health Service Corps. He accepted the position of Medical Director at Desert Senita Community Health Center in the rural town of Ajo, AZ. There Dr. Mulcahy practiced medicine for four years as the town's sole physician while supervising two physician's assistants.

His last two years were spent at the Fem Centre, an integrative medical practice in Fort Worth, TX. There he worked with two other Board Certified Gynecologists who specialized in Women's Bioidentical Hormone Replacement and Detoxification. While at this practice Dr. Mulcahy saw both men and women and treated all family practice as well as hormone related conditions, using a holistic approach.

Although finding the Fem Centre to be a very rewarding experience both personally and professionally, living in the congestion of the Dallas/Fort Worth area became difficult. While in South Portland during his residency training, Dr. Mulcahy and his family knew that Southern Maine was where they wanted to eventually settle, specifically in the Kennebunk area. It was this sense of knowing combined with his six years of private practice experience, seeing the benefits and shortcomings of our current medical system regarding chronic medical conditions, which led to the creation of Southern Maine Integrative Health Center.
