Some of Jon’s other interests are watching baseball (Go Sox) and basketball (Go Celtics). Jon also really enjoys Tae Kwon Do where he and his oldest daughter Kailey earned their black belts together early in 2014, Kim (his wife) earned her black belt in December 2014, and his youngest daughter is currently working towards her black belt.

I would like to thank my wonderful wife, Kim, without whose support, encouragement, patience, and understanding, this book would have never been written. I would also like to thank my two wonderful daughters, Kailey and Kara, who have both been my inspiration and driving force since the days they were born.
