I used Dr. Karen Vaniver. She was the only one in the area that was even willing to consider talking to me, because of my disability. Everyone else I contacted either never replied, or politely suggested I was not a good candidate for it.
She was fantastic, in terms of how she handled me during office visits and her willingness to do what it took to make the process as easy as possible for me. I had the double-incision with nipple graft. I'm just about a year post-op now and I'm mostly very very happy with the results. The nipples look a bit odd, not sure those will ever pass for cis-guy nipples. But the scars are very small and might even fade to unnoticeable in another year (I'm hopeful!). I do have moderate sensation in my nipples, enough for erotic sensation even, but not like I had before. There were no complications, nothing went wrong, I healed up well enough though it was slow going. She was very attentive with post-surgery care, which I really appreciated. Her office manager was awesome too, very friendly and encouraging, very respectful. Which, given my being obviously disabled in ways that make most even otherwise wonderful people treat me like a retard, was more than I ever expected.
I did have insurance problems after the surgery, and trying to get those resolved was a pain. I'm still not completely sure if they are resolved or not. But that was the only negative and really it was only communication difficulties from her office, the rest was my stupid insurance. I would highly recommend her.
That said, I'm not entirely sure she is still doing this kind of surgery. I do know that another surgeon took over her private practice and she moved to another clinic (or a hospital?) in the Seattle area, but I don't know the details.
Feel free to pm me if you have questions.
