I would suggest contacting the NYCOM admissions department and seeing if you could spend a day shadowing there. I am assuming you are applying in next years applicant circle, because if you are deciding for this year you should have already done your reasearch.
Talk to current students...everyone will have likes/dislikes about it.
I was impressed with NYCOMs MSI and MSII courses, OMM facilities and their clinical curriculum.
If you do a search on here there are a lot of random threads talking about NYCOM versus other schools, info about NYCOM, etc... You could also try looking in the Osteopathic forum, lots of people already at NYCOM have opinions too. Hope this helps
