The 2021 Congress will be held on October 15-17, 2021 at the DoubleTree by Hilton Hotel in Portland, Oregon. GWCO Congress was developed to provide an educational venue for the optometric professional in GWCO member states to come together and receive high-quality, multi-track optometric education. As a way to encourage participation of members and state leaders, net profits from the annual congress are returned to the GWCO states based on an attendance formula.
