Neurologists in Washington State?

New to this group but have dealt with MAV for over 5 years, very rarely symptom free. Within the first year did many medication trials, all of which made me feel worse. Have settled for Lorazepam,as needed, but try not to take it at work because it interferes with my memory. So tired of feeling bad all the time. Ready to try a doctor again as i am reafing new research since my MAV began in 2008. Looking for a doctor who is well versed in MAV in Washington State, preferably Central Washington or the Seattle area. Any suggestions? Thanks do much.
