Mark Horvath is living out his passion and doing what burns deep inside of him. In 2008, he founded Invisible People, a Los Angeles–based nonprofit organization, to educate the public about homelessness through innovative storytelling, news, and advocacy. Horvath launched the organization to give a face and voice to people experiencing homelessness, something he knows all too well, since he once lived among them. After an extended period of unemployment due to the 2008 recession and facing homelessness a second time, Horvath grabbed his camera and began using social media to help tell stories of unhoused people.

Horvath regularly works on cause campaigns with corporate clients, including major brands like Hanes, Ford, Pepsi, General Motors, and Ritz Crackers. He has consulted for the city of Los Angeles, Los Angeles County, the Los Angeles Police Department, the state of Utah, the city of San Francisco, the Annenberg School for Communication & Journalism at the University of Southern California, and others.
