David's art career officially began after his formal training from the Pilchuck glass school, for the first time in 1999. There he studied the art of shaping and polishing under Mark Taylor. From this experience and work in the class David developed a unique style of cutting crystal based on his observations of crystal and ice and strived to exemplify their characteristics and enhance light in his creations. While attending college he began showing his work in local galleries and evolving his style. In 2004 after graduation, David attended Pilchuck again and continued to improve his sculpture techniques. His style became more detailed and precise. In 2004, David was commissioned to construct a five-foot sculpture of the Google logo out of his crystalline style. This helped him him to move to San Diego and to set up his own studio.
Now in San Diego, David started to focus on smaller sculptures. At a farmers market in May 2005, a young lady asked David to transform one of the custom paperweights into a pendant, and that was it, David found his calling. He began to focus his unique signature techniques into the creation of his LeightWorks Crystal Jewelry line, which he continues today.
