There wasn't much in the way of information available when I was transitioning. For my nose and neck, my endo recommended a plastic surgeon who he knew and I never produced a review. For GCS, there was only about one choice and we shared what we knew in group therapy.
My voice was a little different story. I looked at two surgeons but I really wasn't happy with everything about them. One I was very nervous about the results. The other had good results but I wanted something a bit different. I joined this site when I discovered there was discussion about Dr Haben and I look at the other members results along with asking questions. After the surgery I started a thread and posted updates until I was far enough along that I didn't have anything to add. In addition, I have remained on the site and if somebody has questions, I do the best I can to provide answers.
