I'm from Brooklyn and had to make this decision last year. Cost was a number one issue for me too. It shouldn't matter if your going into PC or specializing, $100k over 4 years was a big difference. I can't really say anything about how they teach at NYCOM, but LECOM-Erie does a good job. I feel prepared for everything I'm doing here.
Don't get all caught up with "doing" things because most likely you probably won't have much time, although there are things to do in Erie but not compared to back home. I'd also like to say that it's actually a plus because it's easier to focus. Every administration has it problems but the educators are excellent at LECOM. Matchlist is always representative of the class, being that there are many students from the boonies who want to return and are looking for primary care regardless.
In that sense, LECOM does have a decent matchlist but you shouldn't get too caught up with that because it really relies on the individual. I do find and make time to make trips back home though which is always a nice break. It's only 6 hrs lol.
To end, I've heard NYCOM has a board pass rate of 70% or so ( I could be wrong, maybe a NYCOMer can correct) but LECOM is in the 90s. They really emphasize the boards. Don't underestimate the age of the school because LECOM is coming up in the osteopathic world. From my sense, it seems as if they have something to prove lol but they're doing a good job at it.
Dress code is fine with me because it does give me a sense of professionalism. Attendance is only an issue if your a LDPer who is not doing well. I've missed and miss plenty of classes that I don't get much out of the lecturer. To be honest, I've made modified ISP lol. I won't continue blabbing so if you have any other questions just shoot me a PM.
Good luck on your decision! I'm happy with mine!
