@LeadingWithGuts, Jonathan Cheris

Jonathan Cheris, of Roslyn, has Crohn's Disease tweets about his experiences with the disease and raises money for the Crohn's and Colitis Foundation on Long Island. In the past two years, Cheris, 46, has raised more than $26,000 by running half-marathons every six months. He solicits personal sponsorships through Twitter, and he keeps his followers posted on his training. “Twitter has introduced me to others with Crohn’s Disease, and now I follow others and we trade posts. I am making new, interesting connections, and it is just really good all around,” he said.
