I'm a Wichita 2nd year - I've personally enjoyed it down here but I also wanted to go here as I live in the area already. We're a close knit group of people. I know everyone in my cohort + most of the class above and below me, and even a good chunk of the 4th years. I also know a ton of the admin/staff/clerkship directors already cause they help out with tons of random things. I hear good things about our clinical experiences, but I'm not quite there yet.
Ancedotally, I do really like Wesley and Via as hospitals and the physicians I have followed out of both for SER weeks + worked with for projects/research are incredibly nice people who have been interested in helping/educating me. Heck, at Jaydoc (volunteer clinic), some of the docs pretty much let me make decisions as a second year and have shown me how to do minor procedures (hooked up and ran an EKG, gave some injections, ultrasounds, that sort of stuff). More than I expected to get to do, and they're residents/faculty, so, bodes well for what's coming up in 2 months for me I think.
As far as switching I don't know that there is an official way to go about it really? The best he can do is ask because the worst that happens is they say no, right? I think that had some exceptions listed when we originally were assigned, but I dont recall them. FWIW, many of my classmates have kids here. He wont be alone if he ends up with us!
Anyone who has questions re: wichita can feel free to ask me/PM, I'm happy to help answer what I can.
