Here's an e-mail I received from somene who attended LECOM. Maybe it'll give you some insight.
"LECOM is an excellent medical school and it definitely prepared me well for internship and residency. The classes were well structured and set up as a systems approach. This meant that your first year you took all the basic classes like anatomy, biochem, pharmacy, etc. Then you studied each system of the body like cardio. You study anatomy, physiology, pharm, etc all about cardio and then moved onto the next system. I liked this very much. The rotations were great. You have a lot of hospitals to choose from big, small and get a feel for where and what you want to do when you are finished. This worked out great for me.
As for the osteopathic ideas, they emphasize treating the body as a whole instead of as each disease separately. You learn a lot of manipulation techniques, which some people use throughout their practice and others don't. Some people just use them on friends and family. As for the rest of medicine, it is all the same as MD's".
