SAN DIEGO -- John Greenwell says that volunteering and giving back nurture his soul. As such, he participates in numerous organizations both in and out of the LGBT community that help those in need.

The 33-year-old seems to never have a day off. If he's not working, he's participating in a community service project, or in meetings helping to plan ways to make the world a better place, or learning how to be a better leader. As a schoolteacher, Greenwell is also able to instill his sense of service in the students whose lives he touches everyday.
