Hi Nick,
I am located in Seattle too and it seems to me the Seattle doctors are very behind the curve when it comes to ADR. I would be interested to hear from others in Seattle too. Specifically if they know of any doctors conversant in and supportive of ADR.
There was a doctor in Kirkland that once advertised regarding ADR but I was never able to learn much about him. His site is located here:

His name is Reginald Knight. I know nothing about him or his practice, I just pass this on as a potential lead.
In any event, best of luck in your journey.
