As the global community attempts to grapple with the global Coronavirus pandemic responses, healthcare facilities nationwide have begun to implement changes to our operating procedures. To address these concerns, we here at Coastal Treatment Services have begun implementing additional janitorial services as well as alterations to existing treatment services to reduce possible exposure to patients and staff.

However, due to the nature of the services CTS provides, we are considered an “Essential Service” and thus, in accordance with Governor Inslee’s proclamation, CTS will CONTINUE TO REMAIN OPEN until notified otherwise. We thank everyone for the patience during these times.

For the most up-to-date information, please contact our staff directly at 425-646-4406 or [email protected]
