George Zambelli Sr. attended Duquesne University and joined his family upon graduation. With his business and educational experience, he developed an infrastructure with a number of family and young non-family members (some who would remain with the company for 40+ years).
With the support of his wife Constance, matriarch of the family, George Sr. became an icon in the pyrotechnic industry and the envy of his competitors, increasing the number of displays from 8 the week of the 4th of July to over 800 that week at the turn of the century and over 2200 displays per year.
George reviews annual Washington Mall display with National Park Service.
