I'm a MSI in the Navy HPSP at LECOM and there are quite a few in our class. LECOM is a military-friendly environment, from the bookstore manager (she helps out a ton when it comes time for you to purchase books and get reimbursed) to the President and Dean (Dr. Ferretti has family in the Army, a brother and nephew, I believe, who are both orthopedic surgeons who've recently completed tours in Afghanistan)
...and if you have any HPSP questions about any branch of the military, there are plenty of upperclassmen to help you out.
