Why I chose Minnesota: I chose Minnesota for several reasons. The residents and faculty I met on the interview day felt genuine and kind and I felt like this was a group of people that I could go through the difficulties of residency with while having fun. The clinical and research experiences at UMN played another huge factor in my decision. We have experiences of all varieties -- from our complex patients at our tertiary referral university hospital setting to a more typical clinical presentations at our community hospital experiences which allows us to learn about the same disease processes at different acuities and with different resources. We see a diverse patient population and provide surgical care to many of our communities most vulnerable. With the different sites that we operate at, I get to see a wide array of practice patterns which will help me determine how I'd like to practice surgery in the future. The research years were a large appeal to me as it provides the time to be able to explore different types of surgical research from preclinical modeling to clinical outcomes, work on my own leadership development, and develop a new skillset to start off my career as an academic surgeon.

Why I chose Minnesota: When I interviewed with the U, I was impressed by the level of camaraderie and support between the residents and between residents and staff. The complexity and breadth of surgical education and research here is amongst some of the best I'd seen during the interview process. I'm excited about the support we have here to pursue any and all aspects of general surgery and it's subspecialties as a career.
