I've been watching your post with interest. My college roommate in another state is a Geriatric MD and I know it's a specialty in great need - with few specialists. In some cases that is because of the (relative) lower pay, fewer residency programs, etc.
Isn't that area MedStar? I believe they are affiliated w/Johns Hopkins which should be excellent.
A good pharmacist - or ask one of the local pharmacists. Managing the meds of seniors is a primary concern. Good luck.
