The SNMA conference is designed for medical students and to a lesser degree for pre med students as well. The SNMA conferences, as I recall, are more of a catching up type deal with other minority medical students from around the country. It is truly a meet and greet and more ofa social affair than a policy making or business affair. Maybe it has changed over the years, but I doubt it. Not that this is a bad thing, but it is in stark contrast to the other organizations.
The AMSA conference is a good meeting to attend. It rotates each year between being in Washington, DC, where the AMSA headquarters is located, and another site around the country. AMSA is a very "liberal" organization. The AMSA meetings are casual or rather not as stuffy as the AMA meetings may seem. Minority students are DEFINITELY welcome and should participate in organizations aside from the standard SNMA, APAMSA and BLHO. AMSA is a policy making vehicle like the AMA Medical Student Section (AMA-MSS), but the issues that each organization deals with are "different." If you attend each organizations conferences in a given year, you very well may not see the same faces each time. The organizations attract different people.
AMA conferences are fun. It is a great time to network and to learn about things going on in medicine at all levels of training. There is specifically a Medical Student Section of the AMA that meets during the annual AMA conference to conduct business. The AMA meetings are the most formal of all the conferences. The AMA is the business arm of the medical community. More minority medical students should become involved in the AMA and seek leadership positions. The AMA has a minority affairs committee that may be of some interest.
One of the organizations has a representative to the NMA. I want to say it is the SNMA, but it could be the AMA.
Another good opportunity for medical students for sure is to attend the conferences of specialty organizations. Most professional organizations offer student memberships. The ACP-ASIM offers free student membership in fact.
