As per Washington state guidance, masks are required regardless of vaccination status in all of our facilities. Please be aware that if you do not have a mask when you arrive we can provide one for you or reschedule your appointment. Exposure to someone that has tested positive for COVID requires a 14 day wait time regardless of vaccination status or a negative test before being seen in person. We appreciate your understanding!
