In my opinion I think you should definetly look into starting some kind of group based on something that a vast amount of the undergra student body might take interest in...
Black Student Union
Minority Association
Something Sports or League related
Talk to some of the Chiropractic school students who are already in some sort of Club or Org.
Plan mixers with your group and theirs it will help bring awareness about your new group as well as provide something fun to do.
you can feel free to pm me
and if you have instant messanger we can talk via there
For undergrad I had a similar situation and it actually worked out well. I just graduated in June and the Black Student Union grew greatly
just takes time
