Medicine skipped a couple of generations in Dr. Stephens’ family. His great-grandfather was a practicing DO in rural Missouri, and Dr. Stephens grew up hearing stories about how his great-grandfather traveled to farms on horseback to deliver care (even babies), and he would deliver emergency care at his street corner office in town. When Dr. Stephens attended medical school, he would meet people who recognized him who would point out that his great-grandfather delivered their sister or took care of their mom. Seeing the impact his great-grandfather had on his community is what initially brought Dr. Stephens to study medicine.

Dr. Stephens’ medical interests are broad – including outpatient primary medicine, reproductive health, women’s health and obstetrics, LGBTQ+ health, preventive medicine, osteopathic manipulative medicine, rural and underserved healthcare, health policy development and many things in between. Outside of work, Dr. Stephens loves spending time outdoors camping, hiking, biking, paddleboarding, playing volleyball, skiing, cooking, and spending time with his family and dogs.
