I'm in WA State too and the first seminar I went to I found I didn't care for the Dr. For some reason he came across, at least to me, as a bit condescending. His approach seemed like he was trying to "save the world" from having any obese people.
The surgeon I went with is a fast talker, straight to the point, but very very knowledgable. I had to lose 12% of my body weight which I have and then some - my surgery is scheduled for June 4th. What I am really happy with is all the care he takes with your pre-op results. I had a history of cancer and during my abdominal ultrasound it showed a liver hemangioma that I have had for quite some time - my Dr had me get my last CT scan and he sent it and the US for a 2nd opinion. I'm happy with my choice of Drs which is so important because as you get closer to surgery you seem to 2nd guess everything and that last thing you want to do is 2nd guess your surgeon!
