Why I chose Ohio State: I chose OSU because of the amazing camaraderie and friendship that were truly palpable in every room I walked (or virtually "Zoomed") into. Every person in the program, the coordinator, PD and wonderful residents that I interacted with throughout my interview process, was so kind and thoughtful; it felt like I was right at home after every interview and "spotlight night". I also loved the family medicine program at OSU because of the intense exposure residents receive to all aspects of holistic, broad-spectrum patient care. From the longitudinal ultrasound integration to continuity OB deliveries to underserved patient care, residents at OSU are trained from the best to not only be confident and competent to practice medicine, but also serve as patient advocates in the community.
