About Caitlin MacMillen, DO

Caitlin MacMillen, DO, MPH, is a board-certified family medicine physician dedicated to providing full-spectrum primary care to adults and children, with a special interest in women's health and integrative medicine. As an osteopath, she has a whole-body approach to medicine and is experienced in osteopathic manipulative treatment, a type of hands-on care that diagnoses and treats illness and injury by moving a person's muscles and joints to ease pain and increase mobility.

Dr. MacMillen completed her residency in family medicine at UC San Diego School of Medicine, where she was chief resident. She earned her doctorate of osteopathic medicine and a master's degree in public health degree, both at Touro University College of Osteopathic Medicine in Vallejo, Calif. She is board certified in family medicine.

Her experiences abroad, including participation in a pediatric oral health and nutrition project in the rural communities of El Salvador and Ecuador, inspired her to pursue a medical school that also offered her the chance to get a master's degree in public health.

In her free time, Dr. MacMillen enjoys ocean swimming, hiking, yoga, playing soccer, cooking and spending time with family and friends. She also likes to practice speaking Spanish and Portuguese.
