The Diamond Directors Approach

Clients who commit to working with me, must first understand that I don’t specialize in quick fixes and I don’t own a magic wand. Learning to play the game of baseball is an ongoing process and both myself and my clients have to be committed to that process. I don’t train my clients for this weekend’s game, I train my clients so they will have a future in the game of baseball. Clients who are:

  • willing to trust my expertise
  • realistic about their development and goals
  • and willing to accept failure as a necessary setback to achieve their goals will experience the most success under my tutelage.
