According to its website, the University of Kentucky College of Medicine has a Business of Healthcare student organization. I wonder if the club also includes students from nursing, pharmacy, and other health professions. Medicine is a team sport, so it would make a lot of sense to include them.
The Philadelphia College of Osteopathic Medicine,the Johns Hopkins University School of Medicine, and Northwestern University School of Medicine list their Business in Medicine clubs on their websites. I'm sure many other schools use Business in Medicine (BIM) as the name of their club.
The University of Toledo College of Medicine calls their group the Business of Medicine Organization.
At the NYU School of Medicine, the student club is called the Business and Economics In Medicine.
As Temple University, you may run into students who are involved in the Medical Entrepreneurship, Design, and Innovation Collaborative.
The Florida State University College of Medicine has the right idea with BAM: Business and Medicine.
The University of Cincinnati College of Medicine has a Business of Medicine Interest Group for students.
At the Georgetown School of Medicine, don't miss the BLIMP (Business & Leadership in Medical Practice).
My favorite student club is the Medicine & Business Association (M&BA) at the Boston University College of Medicine. Don't confuse that with MBA.
If your medical school doesn't have an organization to support students who also have an interest in business, consider starting one. After all, it's easy to start a student group. The Albert Einstein College of Medicine even has a Game of Thrones Society.
