OMT professors at Touro California are top notch & are well known in the inner circles of AAO.
In terms of newness, I believe it was Touro Nevada that opened up first, then CA, then the others.
I would advise against picking a newer school, much hasn’t settled yet including curriculum and test questions , clinical rotations etc.
Nevada’s “campus” is one giant square building with cardboard line walls Between rooms.
California is on an abandoned Naval Base on Mare Island.
In CA campus, you can go visit/study in SanFran or Berkeley.
In Nevada, you can enjoy Oven-Baked hotness and the Vegas strip to celebrate after exams. Closer to Tahoe for snowboarding etc.
Depends on how miserable you are in 120 degreee weather.
