He has a little dog named Sweet Pea as well, and she's well, she's interesting. Other than those things happening in life he is a lover of reading, watching TV and movies, and has recently become an avid fan and participant of water polo (with a little swimming in there for good measure).

Coach Andy is ready to roll with MACS once again!
