Marilyn S. Darr MD

Family Medicine
As a family medicine physician, Dr. Darr is a member of the American Board of Family Medicine and numerous other professional organizations. Her clinical interests include preventive care, geriatrics, menopausal issues, bone health and pharmacology. She is also a certified clinical densitometrist and has given many community talks on menopause and other topics. "I believe in the whole person, not the parts. I look at a person in total. Every person that I see has a story that relates to health and who they are. Getting to that 'story' is important to changing behaviors. What are their wants and needs?" Dr. Darr is from Basin, Wyoming and outside of work, she enjoys reading and walking. Her personal adage is "Get it done and get it done with humor, if possible."

Brian C. Lowell MD

Sports Medicine
Family Medicine
Brian Lowell, MD is a family practice physician who specializes in sports medicine. He earned his medical degree at OHSU, and completed his residency and sports medicine fellowship at Family Medicine of Southwest Washington. Although Dr. Lowell is board certified in sports medicine, he continues to provide all-around family care. "I really enjoy working with children, and if weren't a physician I would probably be a teacher," said Dr. Lowell. His philosophy of patient care is to begin with with a "less is more" holistic approach before advancing to more aggressive interventions. Despite his advanced training in sports medicine, Dr. Lowell still takes great pleasure in providing family care. "There are not many board certified sports medicine doctors who still deliver babies!" When he is not caring for patients and families, Dr. Lowell cherishes his time with his spouse and children. He is a bit of a rock hound, and says his family enjoys spending time together outdoors on a constant lookout for rocks and minerals.

Joy E. Matthews MD

Obstetrics/Gynecology
Dr. Joy Matthews is an OB/GYN whose interests include office gynecology, contraception, pelvic pain, pain with intercourse, Vulvodynia, Vestibulitis, Obstetrics, Patient Safety and Quality Improvement. She is a fellow of the American Congress of Obstetricians and Gynecologists. As the daughter of an obstetrician, she grew up confident she wanted to be a doctor and certain she would "never" be an OB/Gyn. She stayed firm through three years of medical school before finally admitting it was "far and away the most fun specialty. The relationships I have with patients and the privilege of being involved and hopefully helpful during pivotal events in their lives is something I cherish." Dr. Matthews is a self-declared "army brat" and counts among her favorite pastimes reading and helping friends and extended family as an unofficial medical consultant.
