From what I have heard, both schools are good.
I interviewed at NYCPM and I liked what I saw. The only downside was that it was in the middle of Harlem. The high cost of living and a somewhat shady neighborhood is what kept me from considering it any further.
I did not interview at Western but being that Dean Harkless started the program...I'm sure it will become a very good school sooner or later. But that's the thing with western. It has promise but, in my opinion, it is too new.
With the impending residency shortage do you really want to 'chance it' at a new school which promises to open up ~50 new residencies? New York State has a TON of residency program already in place. I also do not like the way Western is 'thinking' of doing their clinical rotations. I say 'thinking' because, correct me if I'm wrong, nothing is set in stone yet as to what rotations are going to be done and where. I have heard that Western wants their podiatry students to take the same rotations as the DO students. But why spend time in OB/Gyn, Psych, Optho when you could be doing audition rotations at prospective residency programs? Also, how is the seating situation doing at western? I heard that there aren't enough seats for all the DO, OD, DPM, DVM, PA and Dental students who have class at the same time.
Above all of this, however, is where you see yourself for the next 4 years. Where will you feel the most comfortable based on what you know of the geographical region and how your interview went. Your gut instinct about the program should be at the top of your list when decided which school to go to.
