Dr. Mark Lerner, internationally-known traumatic stress expert, is bringing his wonderful production, "In Session with Dr. Mark Lerner" to the Davenport Theatre in New York City for one night only, November 7 at 8 p.m.  This show, which I saw back in September, is an unreheased "reboot" of therapy sessions with a 9/11 firefighter, Bobby Senn, who suffers from post-traumatic stress disorder (PTSD).  Illustrating Bobby's recovery from the illness, it covers several sessions and shows his progress from his confusion and initial devastation to self-knowledge and peace.  It also features music sung by Dr. Lerner's talented son, David Gabriel Lerner (“Mary Poppins,” Broadway).  Tickets are $50 and all money goes to two great causes, the National Military Family Association and the Intrepid Fallen Heroes Fund.
