I dont think the entire class is all D.O.s but I know they have a good number of them.
Just as an aside, D.O.s are looked upon very highly in the PMR world. Any program that doesn't have a Osteopath in each of there PGY years, is missing out, and in my opinion would not be somewhere I would want to be, especially because I am an Osteopath.
Take care,
