I'm from Columbus!
I've been in the military for almost 9 years now. I would highly recommend looking into the National Guard, either Army or Air. I served one weekend a month and 2 weeks a year with the OH Air National Guard during undergrad in order to graduate debt free. I'm now working on switching to the Army Guard in FL for a commission and a full time officer's paycheck. It's a pretty sweet program and it's filling up fast! You are paid as a LT and get a housing allowance for 3 years (this adds up to around 50k-65k a year, depending on if you have served in the military before or have dependents). The commitment is being a student recruiter for 3 years and drilling for the other years (i.e. one weekend a month 2 weeks a year in the state YOU choose! I repeat the Guard is not a daily commitment to the military like active duty). Deployments are possible after medical school. You can still have a lucrative civilian practice as a Guard doc. You can always go active duty if you love the military lifestyle. Check out
this thread on the Military Medicine forum for all the info.
I respect those doing HPSP, but it's a little too much commitment for me to swallow for the benefits. HPSP is the full military scholarship that pays all tuition, fees, supplies and a stipend for four years. Plus right now they are offering a 20k bonus. That's the benefit; the commitment is doing a military residency (which can be less than stellar and limited in numbers/options), and then serving active duty for four years or more wherever the MILITARY decides they need you. This could be the Middle of No Where, North Dakota or Korea. Deployments are possible after medical school. Compensation for specialties is greatly reduced compared to civilian docs. You can't switch to reserve status if you decide you dislike the military lifestyle.
Do a lot of research before signing on the dotted line. PM me if you have more questions.
