ADHA 2021 is an opportunity to reconnect, discover and inspire one another. When we gather this June, nearly two years will have passed since our dental hygiene community has come together in person. As an attendee or exhibitor, your safety is our top priority.

ADHA is working closely with the Phoenix Convention Center (PCC) to take extra precautions, beyond those mandated by government and local authorities.

UPDATE: As of June 17, 2021 the Phoenix Convention Center has lifted its mask mandate for indoor activities. Masks at ADHA 2021 are no longer required. We encourage all attendees to continue to follow CDC guidelines. Temperature checks remain, and room capacity limits remain.

Please review the health and safety measures below and learn how you can help us ensure a successful Conference in Phoenix. If you still have questions related to Health and Safety, please see our Frequently Asked Questions page.
