Tricare help please.
I would recommend you contact a bariatric surgeon in the area. They would know at least a couple of Primary Care providers.
There is
Dr. Smith: http://www.advancedobesitysurgery.com/default.asp
Dr. Maynard: http://www.samabariatrics.com/
Dr's at Atlanta Medical Center (bariatric surgeons) http://www.atlantamedcenter.com/CWS/FindAPhysician.aspx
One of these should be able to send you in the right direction as far as a Primary Care doctor who is experienced in bariatric surgery.
