I can only speak as a 1st year student at OUCOM, but I can enlighten you on a few points.
-As far as the early clinical exposure, our first quarter is similar to LECOM's (according to bleeker10), however we do have something called CCE's (clinical or community experiences) that are essentially shadowing a doc in the surrounding area and practicing taking the history, doing a physical or part of the exam, and even going out on a limb and trying to diagnose the patients. Personally, like bleeker stated I do not find these to be vital by any means, but some people really enjoyed them (so I guess it is up to the person.)
-Secondly if you do become a pediatrician you will absolutely need to minimize your debt for school OOS at LECOM is 27,250 and OUCOM's instate for you would be 24,111. So they are pretty equal, but OU is a little cheaper.
-At the beginning of second year you are placed into your CORE sight based upon your ranking of the programs and a "lottery". This isn't always as bad as it sounds because it is rare anybody ever gets less than their 3rd choice. However if you want Columbus, Cleveland, or Dayton you may need some luck. Once you are at a rotation you stay at that location unless you choose to do an elective elsewhere (which I personally like). I wouldn't want the stress of packing up all of my crap (and paying for moving expenses) over and over to move to different states or locations. Also, from what I have heard about other programs (NOT LECOM-E specifically) is that it can be difficult to find housing, or even set up the rotations at these new programs.
-Finally, OUCOM has NO DRESS CODE or MANDATORY ATTENDANCE! I do think that these two policies make for more professional environment, but I prefer to study from home in my pj's.
Clearly I do have a slant to my post, but it is really about seeing what you believe is the best fit for you. LECOM and OUCOM have great reputations (especially locally) so I do not think you need to worry about going to either one, just pick the one that fits your style the best.
