SDN Members don't see this ad. (About Ads) So I'm applying to dental school right now and upon acceptance will opt in to the HPSP program. My question is can I also serve in the reserves while in the HPSP program and while I'm attending dental school? I don't plan on making a career out of the military but can't say that I won't right now either. I would like to keep this door open and if I chose to do the career, I would like to have those 4 years of dental school count towards my 20. Under HPSP they would not, but if I could somehoe do reserves on top of all of this, I could. So.. where do I stand in all of this? Thanks.
