Ahh, decisions, decisions. I go to NYCOM, so I can offer that POV. First off, both are good schools, so you're in a win-win situation. Think about the money definitely, but dont make it your deciding factor. NYCOM's OPTI has some incredible, very sought-after residencies, but they dont have any ortho as of now I think, although their supposedly working on getting 2 slots. You do get to see alot of ortho at some pretty prestigious affiliated hospitals on rotations though. There's a fair amount of ortho-wannabes here, as it's pretty popular right now. The Sports Medicine folks are really active and they have alot of ortho contacts it seems.
Make sure you want to live in NY. It takes some getting used to if you've never lived here 😉 But, there's some benefit in the area in the wide ranging pathology you get to see. People may disagree, but the diversity of the pathology you get at NYCOM is, IMO, second to none, yes, even better than some of the "power MD schools". You rotate through many of the same hospitals as students from Cornell, Yale, Stonybrook, and Einstein. I think they have about 35-40 affiliated hospitals. The first 2 years at nycom are definitely tough, but the administration is very responsive to student concerns and although they push you, you're appreciative for it in rotations. They're really into technology, giving all students PDAs, ethernet connections at all lecture seats and study cubes, and most importantly, all lectures are taped and put streaming on the web, so you can review lectures at home.....this a huge plus, you have no idea!
My largest negatives are the tuition and the cost of living, both high (welcome to NY), but the tuition is actually average for the D.O. world, even if it is still more expensive than TCOM. I know TCOM has a great research center, so if you're really into research, especially in OMM, that may be your place. NYCOM does alot of Parkinsons research and a bit on Alzheimers and neuro development. The parkinson's research center is one of the larger ones in the country supposedly, is directed by a D.O./PhD who also heads up NYU's parkinson's research.
Wherever you go, DO or MD, if you want ortho you'll have to shine. Do well, make yourself stand out and your school choice becomes secondary.
Anyway, feel free to fire back any questions. hope this helps. good luck.
