Congrats on the acceptances!
I’d probably choose OSU because it’s a great state school, new/fun city for you (especially the sporting events!) and has the opportunities to pursue EM/trauma. Yes there will be a regional pull for residency, but if you want to match on the east coast you could always do away rotations back on the east coast. Also P/F is a dream, huge plus so you can do other things outside of your core classes.
Maryland not being P/F definitely makes it less attractive, but going somewhere you already have friends going makes it easier to settle in/find friends to study/hang with. Shock Trauma is the best of the best in Maryland for trauma, it just depends if you can withstand Baltimore for another 4 years.
Georgetown definitely has name recognition for matching back on the east coast, but comes with a hefty price tag. I really don’t have many pros to say about Georgetown personally, so i’ll defer to someone else for their opinions.
Honestly, if you’re totally okay with starting somewhere new, I think that you would have a blast and blossom at OSU. You’re going to be a great doctor, congrats!
