Special Acknowledgments

First I want to thank God for my life. I want to thank Him for even the most difficult of times, because this has helped me become a man that I hope honors Him in my actions. My loving Godly wife is always by my side, and there’s no question that I could not have achieved any of my success without her continued support. She is a selfless mother and wife. She made the difficult decision to stay at home and support her family; the successes of her husband and her children are God’s reward for her sacrifice. To my wonderful children, Belynda, Melissa, Autumn, Steven, Michael, Meghan, and Brittney—I love every moment we shared together (well, most moments). Thank you for loving me and knowing God.

I would like to thank all the people in my life that believed in me, and those who spurred me on. Thanks to the Electrical Construction & Maintenance (EC&M) magazine for my first “big break” in 1980, and Joe McPartland who helped and encouraged me from 1980 to 1992. Joe, I’ll never forget to help others as you’ve helped me. I would also like to thank Joe Salimando, the former publisher of the Electrical Contractor magazine produced by the National Electrical Contractors Association (NECA) for my second “big break” in 1995.

A special thank you must be sent to the staff at the National Fire Protection Association (NFPA), publishers of the NEC—in particular Jeff Sargent for his assistance in answering my many NEC questions. Jeff, you’re a “first class” guy, and I admire your dedication and commitment to helping others, including me, to understand the Code. Other former NFPA staff members I would like to thank include John Caloggero, Joe Ross, and Dick Murray for their help in the past.

Phil Simmons, former Executive Director of the International Association of Electrical Inspectors (IAEI)—you’re truly a Godly man whom I admire, and I do want to thank you for your help, especially in grounding. Other people who have been important in my personal and technical development include James Stallcup, Dick Loyd, Mark Ode, DJ Clements, Morris Trimmer, Tony Silvestri, and the infamous Marvin Weiss.

A personal thank you goes to Sarina, my long-time friend and office manager. Thank you for covering the office for me while I spent so much time writing textbooks, conducting seminars, and producing videos and DVDs. Your love and concern for the customer has contributed significantly to the success of Mike Holt Enterprises, Inc., and it has been wonderful working side-by-side and nurturing this company’s growth from its small beginnings. Also thank you for loving my family and me and for being there during those many difficult times.
