If you have any plans of building a private practice, DO NOT JOIN THE RESERVES.
I had almost 10 years active Navy and 2 1/2 years reserve. I resigned my commission a year ago (as an O-6 select) because of the insanely stupid manner that the Navy manages reserve activation and deployments.
Navy pay, even if you figure in all the specialty bonuses etc. will not come near your civilian pay, unless you are in one of the lower-paid primary care specialties.
WHEN (not if) you mobilize, your situation will be worse in actuality than the active duty side. First, unless you pay to continue your private health insurance for yourself and your family, you will be shunted into TRICARE. TRICARE is a cruel joke. If, God forbid, you get injured on active duty, you will get shoved off into the VA system. The VA in criminally underfunded and understaffed.
Second, unless you live near one of the larger military installations, commissary and NEX privileges are worthless. Same thing for family support, i.e. chaplains, MWR, etc.
Third, you may be the only person mobilized from your local reserve center. You may be attached to another unit from the opposite side of the country. This means the unit ombudsman will be a complete stranger. So much for (again) for family support, etc.
If you really want to deploy, (and that's what it comes down to) you are better off just going active duty.
Good luck,
