In addition to other sports, Kostis grew up with golf alongside his father, Peter Kostis, who co-founded the instruction operation at Grayhawk Golf Club with his pal Gary McCord. The Grayhawk Learning Center welcomed John to the golf instruction team, where he had already been playing and practicing the game under the guidance of instruction veterans Paul Trittler and Jeff Yurkiewicz.
