Who Deals With Comprehensive Interventional Pain Medicine In Seattle? I

Who deals with Comprehensive Interventional Pain Medicine in Seattle? I heard something about it on the radio (KOMO) and I only get information on line about a Dr. Naranjo in Florida who seems to be a specialist in this field as well as being an anesthesiologist. (My deceased brother was an anesthesiologist, too). I have a son who has had three back surgeries and they have all failed and he is in pain as well as on three kinds of meds. This is no way to live a life. He lives in Bellingham, Washington.
