If there is one thing that I have learned since I became Business Tuesday editor six years ago is that movement of executives from one bank to another is pretty common place. For the most part, these moves don't really surprise me, but I have to admit this latest one did somewhat. HeritageBank of the South, which recently purchased five Park Avenue Bank branches, including the two in Statesboro, just announced that Gary Johnson has accepted a position as southeast Georgia regional president for the bank.
