Meet the Team of Plumbing and HVAC Technicians

  • Jerry

    Technician and is now the General Manager. Jerry and his wife Shelly live on a small farm near Boonville, with their daughter Kalani attending college nearby. His two sons both serve in the U.S. Air Force: Josh lives in Florida when not stationed in Afghanistan, and Logan and his wife Courtney and Jerry’s new grandson reside in Germany. Jerry enjoys the family work environment of MasterTech and being able to share his knowledge and experiences with a true group of professionals who give their best every day.

When Laura is not working, which is not often, she enjoys cooking, reading, and watching movies. Some of her favorites are “Red,” “Dan in Real Life,” “The Holiday,” and “White Christmas.” Why has Laura stayed with MasterTech for so long? “I enjoy the people, the food they bring in for special occasions, laughing with my coworkers. I enjoy the emphasis on improving ourselves as individuals and as a company.” Oh, and if you want to give Laura a gift of appreciation, she’s pretty easy to please: chocolate.
