No one in Seattle, Dugi in Portland is out 2 years (takes Medicaid) There is Stiller in Idaho and Meltzer & Ley in Scottsdale, however, they will be in Portland starting in June. Not sure what insurance Meltzer and Ley take, I have Kaiser and it was covered. A call to your memeber services might be a better place to start for Premera.
Take care,
Margaret
