Lessac pursued his interest in health and wellness with voice and movement and gained a Bachelor of Arts degree in Voice-Speech Clinical Therapy from New York University in 1941.
Instead of simply reading the sermons from the weekly scrolls, Lessac taught them how to commune with the text and inspire their audiences through their vocal delivery.
Lessac continued his studies in neurology and anatomy as he helped patients regain sensation in their faces and mouths through vocal explorations.
Lessac helped patients with a myriad of afflictions ranging from stuttering to gaining mobility in parts of the face lacking nerve action due to Bell's Palsy.
Moreover, Lessac's work reiterated the importance of allowing the pleasure of feeling vocal vibration or body's energy guide one towards optimal expression and wellness.
Famed directors Elia Kazan and Robert Whitehead[disambiguation needed] appointed Lessac as teacher of voice, speech, singing and dialects for their historic repertory company at the Lincoln Center in 1962.
Lessac left SUNY in 1981 as Professor Emeritus, but continued teaching in training programs all over the United States, Puerto Rico (where one of his students was Adrian Garcia),[2] Germany, Yugoslavia, South Africa, and Mexico.
Lessac's teachers and disciples felt the urgency of maintaining the pedagogical practices of the work plus the desire to expand kinesensic research into new terrain.
