Also consider contacting departments that are not traditionally generalist, including emergency medicine, preventive medicine and general surgery. Finally, if you are having difficulty connecting with generalist physicians contact your dean or associate dean's offices and ask for their suggestions. If you know what you want, be as specific as possible when talking to physicians. They probably have great ideas for programming. Plus, if they become involved on the ground level they will feel invested in your GPIT group and want to see you succeed.
Many medical schools have funds set aside to help support student activities.
Be sure to investigate this possibility through your student government and student affairs office. Most of these grants will eventually require detailed descriptions of how the money is going to be spent, so jot down your ideas before requesting funds. Pharmaceutical companies may be willing to donate money as well. Also, work on pooling funds with other student groups. When your group is up and running, it is time to become financially self-sufficient.
