The Service Roundtable’s Plumbing, Heating and Air-Conditioning Hall of Leaders was created for those recognized as servant leaders by the group.

The Servant Leader Award recognizes outstanding individuals who lead through service to their industry and the people in their industry. Only five people have been recognized with the award: sales trainer and consultant Charlie Greer (the most recent recipient); air-conditioning pioneer Ron Smith; plumbing contractor Frank Blau; magazine publisher Jeff Forker; and air-conditioning sales trainer Tom McCart.
