Greg Grunberg might be a hero on TV, but the actor told People Magazine that his personal hero is his son Jake, who is epileptic. Because of his son, Greg is an advocate for epilepsy awareness in Los Angeles for the Pediatric Epilepsy Project at UCLA and for the Epilepsy Foundation. Greg and Jake also participated in the annual National Walk for Epilepsy, and he organized Hollywood’s Helping Hands fundraiser, which raised $300,000 to fight epilepsy.
