    Mike has four daughters, all of whom play, or have played, in the PWLL.  His primary reason for coaching is his passion to help young girls develop positive life skills through teamwork, healthy competition, and personal growth.  Nothing makes him happier than to see each of his players improve over the course of the season, gain confidence, and develop a love for the game of softball.
