Mark Gubser and Jamie Schnakenberg have over 50 years combined experience providing both wireless and wired communication products and designing comprehensive communication solutions. Both men were instrumental in the development of the coaches intercom systems used by every FBS school and wanted to take that experience to help more athletic organizations. In 2010, Gubser & Schnakenberg, LLC (GSC) was founded. 

The National Football League was looking for a solution for safe, secure and efficient coach-to-player communications. They approached GSC to design, supply and support the systems which are currently being used on game day and at the individual team practice facilities.

GSC also provides wired and wireless intercom solutions for a variety of organizations and venues: whether integrating new products with existing systems or engineering completely new systems. Mark and Jamie continue to lend their expertise to every product and system design, including customer service and support.
