Marielle Opeña, DO

***Starting in December 2026*** Family Medicine

Dr. Opeña is a family medicine physician who enjoys caring for patients of all ages. She is committed to expanding her knowledge in her growing interest in geriatrics. She believes great healthcare starts with active listening, understanding each patient as an individual, and meeting patients where they are to meet their goals.

Outside of medicine, Dr. Opeña enjoys adventures with her husband and their two dogs (Daisy and Duke), powerlifting, and listening to audiobooks across many genres. She is excited to be back in Maine and looks forward to the opportunity to spend more time with patients and build meaningful, long-term relationships.

Dr. Opeña earned her Doctor of Osteopathic Medicine degree from Burrell College of Osteopathic Medicine in Las Cruces, New Mexico, and completed her family medicine residency at Northern Light Eastern Maine Medical Center in Bangor, Maine.
