Hi Richard!
I had my surgery in Nashville when I lived there - just moved to VA last summer but still have my docs on speed dial in case something comes up.
It is a little bit of a ride for you, but if you're post op and don't need to be seen much, I'd say it's probably worth the trip.
I went to Vanderbilt Otology Group (they have offices in Vandy and also at St. Thomas hospital nearby). I also saw an audiologist at Vanderbilt that does BAHA's. I read they are actually the second largest distributor of BAHA's in the US, after Cochlear in Colorado. They are very knowledgable, and what I really liked was that they have a walk-in FREE repair clinic for any minor repairs.
Vanderbilt is huge and pretty much any type of doctor you need is right there. One stop shopping! Look in your phone book though, because I know they have some offices in other parts of TN, so there may very well be something in Knoxville.
If you want to PM me, I'll send you the contact information and some names. Also, the names of some good places to eat while you're in Nashville!
Good luck on your move!
Lori
