Starting in Los Angeles in 1984, with permission from Sandford Meisner, David began teaching the technique that made Mr. Meisner famous and put thousands of his students in productions from film, Broadway, local theatre and television. Meisner students included, Gregory Peck and Eli Wallach to present day Academy award winners. The Meisner technique is beyond reproach . David continued teaching there for the next 20 yrs.

As with Mr. Meisner, the attainment of becoming working actors continues to be a result of this incredible way of performing in all mediums, as David and other Meisner trained actors continue to teach.
