Washington State is fully re-open as of June 30th, 2021. For the safety of all attendees GTSE currently plans to require masks at all times during the event, regardless of vaccination status, with the exception of meals. GTSE takes the safety of its exhibitors, sponsors, partners, speakers, and attendees very seriously. As the situation with COVID-19 is changing daily, we are closely monitoring the response by healthcare and government officials so we can ensure the protection of all our stakeholders. We will continue to update our sponsors & exhibitors as changes are made.
