[1] Grant chooses to share his professional acting, directing, and acting coach background because the leap from directing and coaching actors to coaching Executives and Individuals was virtually seamless. Both are critical to positive and sustainable behavioral change. In spite of his business degrees, leadership training, seminars and workshops, and post graduate education although invaluable the insights and experience he gained from 20 years as actor, director, and acting coach are unparalleled. This was, in part, due to the enormous understanding he gained about the human condition.
