Kevin Mather

Kevin Mather
(aka “Moonbeam”) has been mixing chemicals and playing with fire since he was given a chemistry set at age 8. When asked about how he got started in pyro, he quickly answers that his mother is primarily to blame. Growing up in Colorado, fireworks were a common part of family celebrations and were actively encouraged by his mother. Kevin has been quoted saying, “Birthdays, Christmas, Chanukah, the summer solstice, and most days of the week were all celebrated with fireworks in my family.” Kevin is fascinated by Italian shell construction and attributes this to his love of “cut and paste” in kindergarten.
