About Us

Founded by Chris Masiello, RN MSN & Stacey Sherman M.Ed.

Greater Boston Safety Training was founded by Chris Masiello, RN/BSN, and Stacey Sherman M.Ed., after working as Health and Safety Instructor Trainers for the American Red Cross of Mass Bay. GBST offers a variety of land and aquatics-based courses.

As an American Heart Association Training Site, Licensed Training Provider for the American Red Cross, American Safety and Health Institute, and Safe Sitter Training Center, Greater Boston Safety Training can offer First Aid and CPR/AED courses.

We strive to deliver the best CPR and First Aid training wherever you need it and on your schedule. While group classes may be suitable for some people’s schedules, private instruction at your business or healthcare facility may suit you better. We are happy to provide one of our licensed and certified trainers to come to any location for a group class.
