Kristin Prewitt
Kristin Prewitt, MD, MPH

Kristin Prewitt, MD, MPH (she/her) grew up in Milwaukee, Wisconsin. She graduated from the University of Wisconsin-Madison with a degree in English Literature. It was in undergrad she developed a passion for the nexus between humanities, medicine, and advocacy. After enduring many Wisconsin winters, she decided it was time to explore warmer climates. She graduated from the University of South Florida with a dual MD and MPH in Epidemiology degree.

She then moved to Portland, Oregon for residency at OHSU. Although she initially started residency in Family Medicine, she transitioned to OHSU’s Obstetrics and Gynecology program, desiring to expand her ability to advocate for patients through high-risk obstetrics, advanced family planning, and surgical care. She graduated from OB/GYN residency in June 2023. Her research focuses on substance use disorders in pregnancy, abortion, stigmatized care, and pain management during gynecologic procedures. Having been a teenage parent herself, Kristin also has a particular interest in adolescent gynecology. She is thrilled to continue her training at OHSU in the Addiction Medicine Fellowship. In her free time, she likes to garden, hike, read, and explore the Portland food scene with her two kids and partner.
