Christy's coaching offers so much more than simply learning the dive pool--to fly well, one needs to engineer appropriately, walk purposefully, clearly understand the formations, recognize the role each flyer plays, and think. But even more to the point, each person coached receives personal attention to develop their skill, celebrating successes and examining weaknesses.
