HolotropicMA - Breathe   -   Explore   -   Evolve
About Us
HolotropicMA is a collaborative project initiated by Allen Howell, M.Ed. that invites GTT certified facilitators and apprentices from throughout the US and beyond to bring the practice of Holotropic Breathwork™ to Massachusetts.

All of our facilitators have completed a rigorous training and certification process through Grof Transpersonal Training (GTT) that is designed to offer a comprehensive education in transpersonal theory as well as in the practice of Holotropic Breathwork™. The program concurrently facilitates the trainee’s personal, spiritual, ethical, and professional development by encouraging an ongoing process of self-exploration. Most facilitators feel called to this practice as a "path of service" after having worked with the practice themselves for some time. We at HolotropicMA feel that is our privilege to be able to offer Holotropic Breathwork™ events to those who feel called to utilize it in their own lives for personal healing and growth.

Our apprentices uphold the same ethical guidelines and standards of practice as those maintained by certified facilitators and serve under the careful supervision and guidance of the facilitators.

Talented individuals who collaborate with HolotropicMA include:

Verónica Muñoz
GTT Certified Facilitator

Verónica is a certified Holotropic Breathwork™ facilitator originally from Santiago Chile but now living in the U.S. Verónica was certified by the Grof Transpersonal Training (GTT) in 2009. Verónica worked for many years supporting human resources development as a full-time Organizational Psychologist with a Master in Business Administration. At the same time, she was actively focused in her self-exploration, experimenting with a wide range of healing modalities. With no doubt, HB has been the most powerful tool in this process. Though it, she has embraced inner healing and spiritual awareness. This experience has encouraged her to dedicate her efforts to help others embark upon their own holotropic journeys in a safe, and supportive setting. During the last 5 years, Verónica has traveled extensively and facilitated at Holotropic Breathwork™ workshops and GTT training modules in USA, South America, and Europe.
