Why Michigan Surgery

"I chose Michigan because the program provides world-class clinical training with world-class people. The entire surgery department is centered around resident education and the mentorship residents receive from faculty is unparalleled. There are very few programs in the country that can provide the same combination of excellent clinical training, collegiality, and academic development as Michigan."
