COVID-19 Status Update - Reopening Massachusetts

As of May 29, all remaining COVID-19 restrictions have been lifted. Mask requirements remain in place in certain spaces.

COVID-19 Status Update - Mask Requirements

Effective May 29: The Commonwealth’s mask order is rescinded. The Department of Public Health has issued a new mask advisory consistent with the Centers for Disease Control and Prevention’s updated guidance. Masks are still mandatory for all individuals on public and private transportation systems (including rideshares, livery, taxi, ferries, MBTA, Commuter Rail and transportation stations), in healthcare facilities and in other settings hosting vulnerable populations, such as congregate care settings.

Contact Tracing and Permitted Public Health Reporting

The Privacy Rule of the Health Insurance Portability and Accountability Act (HIPAA) sometimes causes confusion and misunderstanding concerning case reporting and the authority of public health officials to conduct public health surveillance and case investigations. With regard to communicable disease surveillance and reporting, HIPAA does not interfere with state public health reporting laws, nor does it prevent access to protected health information (PHI) for public health surveillance, investigations, and interventions.

About Us

Our Mission

Our mission is to serve the under-served in Western Massachusetts with a passionate and highly qualified team. ABAS is dedicated to using the highest standards for effective Applied Behavior Analysis (ABA) to include professional and ethical behavior and compliance with all applicable federal, state, and local laws related to health, safety, and employment.

At Applied Behavioral Analysis Services, LLC, we take pride in serving the underserved in Western Massachusetts. Our team is here to provide effective ABA in order to help individuals of all ages and developmental levels diagnosed with Autism Spectrum Disorder (ASD) achieve their fullest potential. This is done by building a strong rapport with families and children and by providing services that include home visits, community outings, childcare/school collaboration, and consultation with the family.

At ABAS we use ABA to target skill acquisition, decrease unwanted behavior, and build a lifelong family and child relationship.
