About

Dr. O’Sullivan is a Tulsa native and proud graduate of Booker T. Washington High School. Her journey in medicine began at Duke University, where she conducted research into novel non-pharmacologic treatments for chronic pain through the Duke Pain Prevention and Treatment Research Program. She returned to her hometown to earn her medical degree at the OU-TU School of Community Medicine before moving to Salt Lake City for post-graduate training.

At the University of Utah Health Sciences Center, Dr. O’Sullivan completed her internal medicine residency and was selected to serve as Chief Medical Resident. She remained at the University of Utah to complete her fellowship in Rheumatology, where her research focused on the complex intersection of cancer immunotherapy and underlying inflammatory arthritis.

Dr. O’Sullivan is thrilled to return home to Tulsa. She is dedicated to helping her patients navigate complex chronic diagnoses with a focus on maintaining the highest possible quality of life. Outside of the clinic, she enjoys exploring the outdoors, traveling, and spending time with family.
