David Kasinskas

President & CEO

As a pilot and aircraft enthusiast, David landed a dream job as Mechanical Engineer for Cessna Aircraft Company early in his career. His role at Cessna and his previous experience within the automotive and outdoor power industries helped opened his eyes to a need in the marketplace – the lack of product analysis to improve product designs, reduce material costs, and design safer products. Determined to fill that need, David started GSC in 1989. In 1995, David helped to launch the SOLIDWORKS product and GSC remains as one of the only original solutions providers for SOLIDWORKS. Always on the cusp of the latest innovations, David helped GSC become one of the first companies to introduce 3D printers to customers as additive manufacturing solutions. As passionate as ever about computer-aided design and 3D printing technologies, David is committed to assisting customers in implementing new engineering technologies to streamline product development and fuel their success.
