There are no GRP's in Seattle, However there are 2 GPR's!
One is affiliated with University of Washington and is run by Dr. Ana Martinez, the other is affiliated with Swedish Hospital and is run by Dr. Bart Johnson and Dr. Amy Weinstein. The Swedish program has more of a private practice direction to it and would be my recommendation. From what I hear Dr. Johnson is a great resource and everybody has great things to say about him. He used to run the UW program but then left and created the Swedish one, and I understand the UW program hasn't been the same.
