COVID-19 (Coronavirus): The MAAO is very sensitive to the recent declaration by Governor Charlie Baker with regards to the state of emergency over concerns about COVID-19 (Coronavirus) and upcoming MAAO offerings. The MAAO has made the decision to postpone or cancel upcoming Course/Workshop/Conferences through the end of April.  We are working to inform all current registrants regarding their course offerings.

The MAAO will continue to monitor the information provided by the State as well as the Centers for Disease Control to determine if any changes to events are necessary.  The Massachusetts Department of Health has issued some guidelines with ways to prevent the spread of respiratory diseases like the flu or COVID-19.  Please review the flyer for recommendations on how to stop the spread of germs.
