Current Fellows

Meghan Burke, DO

Dr. Burke is a recent graduate from the University of Arizona Psychiatry Residency Program in Tucson. She was raised in suburban Chicago and has since lived in various areas of the country for higher education and medical training. During her time as a medical student in Eastern Tennessee, she learned the value of humanistic relationships in medicine, the limitations in rural access to medical care, and the importance of approaching health with an adaptable mindset. Through residency, these lessons have developed into a passion for destigmatizing illness through movement away from shame-based treatment and towards collaborative care. Within this mission, her specific interests include health for healthcare workers, multidisciplinary medicine, and addiction medicine. Outside of medicine, Meghan enjoys spending time with her husband and pets, working on their home, gardening, and exploring new places.
