Thats great. My approach to seeing a doctor that I know little about would be to seek referrals from several patients that have been to him for similar issues. I would contact them and I would want to know if they were currently still patients, what treatment they received, how they felt about the doctor and their treatment etc etc. If someone had benefitted from treatment then I assume they would be willing to share their experiences. I know I would.
Even after all of that its still a crapshoot but at least a background check had been conducted prior to making a committment.
