Greg spent over a decade working in ministry first on staff at North Point Church, as tour manager for world-famous Christian singer Chris Tomlin, then part of the small group that launched Passion City Church in Atlanta. He still helps produce Passion Conferences, which bring together tens of thousands of Christian college students from around the world each year.

Greg got involved locally. In 2018, the people of Forsyth County overwhelmingly elected him to the State Senate. He now serves as Chairman of the Senate Transportation Committee and, at the request of Lt. Governor Burt Jones, sits on the powerful Committee on Assignments.
