In the years since he famously graced big screens as Lieutenant Dan in Forest Gump, actor Gary Sinise has become a passionate advocate and supporter of America's service members, particularly through the Gary Sinise Foundation.
The story of his career, from his modest start on the stage to his life-changing role in the Tom Hanks film, and then finding his passion through military advocacy, is detailed in Sinise's memoir, "Grateful American: A Journey from Self to Service."
