Mountaine Mort Jonas is a highly experienced trainer, conductor, actor, and musician in the rich honoring of true personal stories that is called Playback Theatre. He is also a long-time facilitator of Breathwork Medicine, a form of intensive breathing (similar to "rebirthing") which is a potent technique to advance self-knowledge, personal growth, transformation, and healing.

An experienced software trainer/consultant in the nonprofit corporate world (with recent clients including the Metropolitan Opera and the Mayo Clinic), Mountaine brings his professional communication skills to teaching creativity through improvisational theatre, and to leading clients in breathwork sessions. He holds an S.B. degree from M.I.T., where he majored in urban planning but focused on music and theatre. He has pursued experience-based spiritual work for personal growth since the late 1960s, which provides a foundation from which he has developed his abilities in both playback theatre and breathwork.

Mountaine is also the founder of EarthStage Productions, a nonprofit founded in 1993 to produce high-quality theatre designed to educate audiences about social and environmental issues.

Mountaine is known to his friends for his unusually colorful socks, the huge assortment of hats he has collected in Thailand, Holland, Nepal, Brazil, Coney Island, etc. that he wears on occasion (usually one at a time, but not always), and for the combination of frivolity, political perspective, surprising silliness, and serious spirituality which he brings to the table. And the chair, the floor, the ceiling, the great outdoors...
