I've been seeing Dr Hesla at Oregon Reproductive Medicine. Pretty much any of the physicians their rock and they have been voted one of the best in the coutry. I've seen Bankowski, Barbieri and Matteri since most of my IUI"s have been on the weekend so you get the doc that works that day. Dr Hesla is my main doc though. I have friends that go to Matteri as well. Matteri I've found pushes IVF sooner than the other's. Hesla doesn't have the warmest bed side manner but he is wicked smart and relaxed and open to what you want to do. His resume is unreal, Harvard, John Hopkins etc. Barbieri is a woman and super wonderful and gentle. Bankowski I find to be great as well.
I've heard good things about NW Fertility Center as well. Their costs are lower but I haven't been there but know people who love the doctor there too.
