I am currently at Stanford GSB. As an MD, one of the things which may appeal to you about the GSB is the high degree of collaboration with other departments, and the number of students interested in working with and meeting people in fields such as medicine, high-tech, and clean-tech. Although Stanford places extremely well in traditional MBA fields such as PE/VC/IB, you will find that the majority of students here are interested pursuing other careers. Many people joke that employers get frustrated with the GSB because students turn down their offers from McK and Goldman to start their own companies or work for nonprofits.
The GSB makes a strong effort to bring together students from other departments in the same classes and clubs. In fact, there are a number of engineering Ph. Ds and MDs concurrently enrolled at the GSB, and also a large number MBAs who decide to get a technical MS while they are here. (See the E-IPER program). I worked in high tech before coming to the GSB. I wanted an opportunity to use my technical background to do something meaningful. The main reason I chose GSB over a number of other good offers (including HBS) was because I felt like this interdepartmental synergy would help direct me.
Quick anecdote -- a friend of mine started a medical devices company with a Stanford Biodesign Fellow he met here. They have raised money and seem to be getting significant traction.
