I'm in a similar boat, in that I would like to knock out as many things at once that I can. And your assumptions on time limitations are spot on.... there is a limit that a Dr and Anesthesiologist feel comfortable having you on the operating table. You also don't want to rush them. I have only had FFS and Voice consults, although I did have a "mini consult" with Dr. Steven Robinson (In Cincinnati) about body Contouring and breast augmentation. I am only marking my 1 year HRT and he suggested that I do my Face and voice first and come see him next year. I don't want to assume everyone knows about this, and forgive me if you already know.... but the RealSelf website is really awesome. It is community driven and you can research surgeons and people's reviews as well as before/after pictures (You do have to create an account to see any pictures) It has been rather helpful in helping me find qualified, reputable and trusted doctors. It has also helped me rule some out that I had originally picked to get a consult with.
Good Luck Sister and please keep up updated on your search!
