Personally, I'd pick UTSW. Speaking to current students, I've actually heard the opposite of the gunner mentality at UTSW. I heard it's very friendly and not as toxic/competitive as ppl make it out to seem. I've heard other schools, like McGovern, are actually more gunner mentality. Foster is a great school and you'd be able to reach any dream specialty you want there, but UTSW would make that process smoother because of their clinical and research opportunities as well as their excellent board averages. I actually live in El Paso right now for my gap year and its so beautiful here. Truly an amazing city and you'd have a lot to do here, especially being so close to NM and AZ. Ultimately, it just depends on what you value more. Do you value having stronger clinical and research resources or do you value going to a school that has more of an emphasis on underserved populations and border health? Foster's new curriculum is pretty cool & they have a small class size, so take that into consideration as well!! Good luck choosing!!
