After finishing second in the tournament, he was hooked.During his coaching career, Warren County won six district championships, two regional championships, and two Lady Pioneers played in the state tournament.Jamie Caten, whose nephew Bryce plays now, and Tina Volcheck each played in the state tournament under the tutelage of Dunlap.Countless players have learned the game under coach Dunlap and the retiring coach praised the players he got to teach the past two decades.“Coaching tennis, I’ve always had good kids to work with,” said Dunlap. “Our teams almost always had team GPAs of 3.5 or higher and were well behaved.
