Doctor recommendations??

Does anyone know or have any recommendations on a primary health care doctor that accepts tenncare for adults? I'm in Bristol but wouldn't care to drive to Johnson city/Kingsport for the right doctor. I've been going to the etsu family physicians out across from the Bristol hospital but honestly I'm just so tired of never being able to see the same doctor each visit. I've had some rather scary things going on lately and really just want 1 doctor that I can explain everything to and work towards getting answers. Thanks to anyone/everyone in advance.
