My experience at the Portland OR PP was just like Robyn's. The nurse practitioner I worked with was super enthusiastic and helpful - she was ready to provide whatever I wanted, from the minor dose of oral HRT I was interested in initially, up to transition dosages of injections or patches. They're completely non-judgmental of course. On my last followup it took forever to get in and the NP was in an awful hurry, they do a lot of business, and a few months back I switched to just using my PCP, whose offices are right down the road - getting to PP's center always involved fighting a lot of rush hour traffic. But they got me started on this journey, all of it available via signing informed consent papers, and I'll always remember the experience fondly.
Their website's set up very well, too.
