Mark Horvath has broken the mold. He's not doing what makes sense. He's not doing something that even pays the bills. He is living out his passion and doing what burns deep inside of him. Mark has developed Invisible People to give a face and voice to homelessness, something he knows all too well since he once lived among them. His work is extremely innovative and his ingenious use of social media is a model for both the corporate and not-for-profit worlds.
