We are sorry for the inconvenience - the page you are looking is currently unavailable.

COSA is transitioning to a new member portal, which should be available by mid-April. An email will be sent out to all COSA active members with instructions on how to access the new portal.

In the meantime, if you need to make a payment on an existing invoice or have questions, please contact the COSA office at 503-581-3141.

Thank you for your patience.
