Doctors of Osteopathic Medicine, or DOs, are fully licensed and board-certified physicians who practice in all areas of medicine. DOs emphasize a whole-person approach to treatment and receive extra training in the musculoskeletal system called osteopathic manipulative treatment (OMT). DOs at One Medical typically practice in the field of family medicine, geriatrics, pediatrics, or internal medicine, and may also integrate OMT.

About Mary Brigid

As a family medicine physician, I enjoy forming lasting relationships with individuals and families which allow us to truly collaborate in the pursuit of holistic, personalized, and evidence-based health care. I believe that health cannot merely be defined by lack of disease, but rather physical and mental well-being in the context of each person’s unique circumstances. I strive to be down-to-earth and informative, meeting each person where they are on their health journey.

I practice full-spectrum family medicine including women’s health, preventive care for children through seniors, as well as managing chronic disease with a focus on lifestyle and nutrition. I also have special interest in HIV management and prevention. In addition to being board-certified in family medicine, I also hold certifications as an American Academy of HIV Specialist and in Plant-based Nutrition.

How I stay healthy and happy
I enjoy urban gardening, cooking (mostly) plant-based meals, traveling, reading, listening to oldies music, getting a good night's sleep, spending time in the sunshine with my husband and our senior Chihuahua (who keeps us laughing)
