What was your impression of Shippen? I've heard very good things. He seems like a mentor type to Crisler, and that can't be a bad thing!
I'd say his reputation is well deserved. He is a really nice guy and very easy to talk to. Before seeing him I had to write a letter explaining my history and why I was coming to see him. My letter ended up being quite lengthy because I had already been to several TRT docs and tried several forms of treatment. In my 2 hour discussion with him it became apparent that he actually read, no, I would say studied, my letter because he actually referred back to comments that I had made in it. Most doctors I've seen don't look at my records until after they walk into the exam room.
The jury is still out as to whether he can actually help me or not, but I none of the other docs I've seen any idea what to do or try.
