       Holotropic Breathwork™ in Massachusetts

About Us

HolotropicMA is a collaborative project initiated by Allen Howell, M.Ed. LMHC and guest facilitators and apprentices to offer the practice of Holotropic Breathwork® in Massachusetts and throughout New England.

All of our certified facilitators have completed a rigorous training and certification process offered by Grof Transpersonal Training (GTT) that includes a comprehensive education in transpersonal theory as well as in the practice of Holotropic Breathwork®. The program concurrently develops the trainee’s personal, spiritual, ethical, and professional expertise. Most facilitators feel called to this practice as a "path of service" after having worked with the practice ourselves for some time. We at HolotropicMA feel honored to be able to offer Holotropic Breathwork® to those who feel called to utilize it in their own lives for personal healing and growth.

Our apprentices are enrolled with GTT, uphold the same ethical guidelines and standards of practice, and work under the careful supervision of certified facilitators.
