In his spare time, Sam enjoys being with his family. “There is never a dull moment,” he declares. Sam considers his wife, Monica, the perfect partner not only in life but in business as well. He thinks she is absolutely amazing. “She’s the one to take my narrative and put them into the stories of our book,” he explains. “She is also a teacher by trade, has nine children, runs marathons, and takes amazing care of her family. I like to think of her as a ‘Missionary Mom,’” Sam continues, “She’s one awesome lady!”

Outside of Orange County, Sam and Monica, own and run a very dynamic wrestling camp in North Western Montana, the Eternal Warrior Wrestling Camp. It is known as the toughest wrestling camp in America and has one purpose – to make a difference in the lives of young men and women worldwide through the sport of wrestling and through the foundational principles of morality as taught in the Bible. The camp has been continuously running for ten years and is an entire family operation.

On a personal level, Sam enjoys both training for and competing in Ironman Triathlons; and he desires to one day qualify for the world championships in Kona Hawaii.

Monica Vaughan Calavitta is Sam’s wife of twenty years. She has a Bachelor of Arts degree in Liberal Studies and received her multiple subject teaching credential from Chapman University in 1993. Her student teaching assignments were completed in kindergarten and fourth grades and she has both taught and directed at the pre-school level. Monica became one of the original Momsquad bloggers for a local magazine in Orange County, California in 2008 and enjoyed writing for OC Family during her tenure as “Mom of 9.”

Monica feels privileged to be able to announce that she is a “stay at home” mom. She and Sam have nine children, ranging in age from twenty down to two years. The greatest joys she has experienced have been in raising a family and watching the children continue to strive to reach their fullest potentials.In writing this book, Monica worked closely with Sam to be sure each narrative represented his individual student’s story exactly. It is her hope that the stories will be constant and living reminders that all people have the opportunity to make a positive difference in the world around them.
