I have gallstones.

My GP has scheduled me an appointment for tomorrow morning with our surgical group where I live. I think the office didn't specify anyone in particular. It is with an M.D. Now, I have nothing against M.D.s at all. I was looking at their letterhead and saw where there are about 5 M.D., F.A.C.S., and 4 M.D.s.
Do you think I should reschedule with someone that has F.A.C.S. after his title of M.D.? Doesn't it mean he has more experience as a surgeon?
