Can you be happy in a suburb of Milwakee? D.C. rocks if you like big cities. GW has awesome clinical experience, including the first two years, MCW doesn't have any the first two years. Reputation...U.S. News ranked MCW cause they have fat research money, GW doesn't hide the fact they aren't a research based school. If research is very important to you, go to MCW.
But when you compare match lists (both are available through admissions), you'll see that both schools send kids all over the country, including California, and both schools have docs landing residencies in places like UCSF and Hopkins. One matches better in Wisconsin, the other better in D.C. What a big surprise :wink: So the academic difference is negligable. As it is with nearly all medical schools outside the top tier.
As for teaching...GW has a more integrated approach, with a little PBL/Case based stuff. MCW is pure lecture. Again, your decisions.
But, I think the biggest differences between these too is the midwest vs east coast. Which do you prefer?
