A special note about our photos:

We have taken HUNDREDS OF THOUSANDS of photos over the years of our students, instructors, and staff — during classes, after classes, and at various gatherings. Throughout this brochure and on our website, you will see many photos that were taken prior to the onset of the Covid-19 pandemic. Images of people without masks or not practicing social distancing were taken before the pandemic and before the safety practices were implemented. Please rest assured, we follow all of the safety precautions and guidelines mandated by our local and state health officials. Community means everything to us —we aim to provide a safe environment for all who teach and learn at MASW. If you have any questions or concerns regarding our practices, or would like more detailed information about the school’s health and safety guidelines, please do not hesitate to call or email us!
