Great!
Another poster mentioned Whitman and St Olaf. These are great LACs, academicky, strong in STEM, robust merit programs, I would definitely second those nominations for schools you should check out.
Oberlin is probably most famous for their conservatory, but they are another very strong STEM LAC with merit. They are also not far outside Cleveland so lots of local experience opportunities.
Kalamazoo is another really cool LAC with a special curriculum structure called the K Plan. Very strong Bio and STEM in general, and they are located in Kalamazoo, Michigan, which is a decent-sized smaller city, also the home of Western Michigan and its med school, and is a bit of a Life Sciences hub. It is also about halfway between Detroit and Chicago, with trains to each.
Hendrix is another strong LAC for these purposes, in Conway, Arkansas, which is about half an hour from Little Rock. They start with a relatively modest cost of attendance and then add a robust merit program.
Rhodes is in Memphis, and a very popular LAC for premeds with robust merit, and what looks like a beautiful campus (I have never been, but I would like to!).
Finally, Ursinus is about 45 minutes outside of Philly, again strong related departments and robust merit.
This is really just a sampling, there are so many LACs that might be suitable, and obviously you don’t need to apply to a gazillion of these, just your favorites. But I do think taking some shots at any LACs that feel good and have a lot of merit could produce some strong offers.
Edit: Oh, and I meant to second the recommendation to check out women’s colleges if that is at all of interest. Again they tend to hit all the big points of strong in premed-related departments and strong prehealth advising, and some have possible merit as well.
Vassar, a former women’s college now coed, is also great, but no merit unfortunately. Still, it is such a great college it might be worth taking a look.
