Do they do cochlear implant surgery (specifically BAHA)? If not, who does in the area?

Unfortunately no

They do not and do not service them. Larger hospitals only. Your best bet is search the manufacturer's website for location. There's 3 manufacturer's, Advanced Bionics, Cochlear, and Med-el

Not sure but you can call and see very nice doctor and nurse

Im truly not sure but just give them a call
