GSE Dynamics was founded by Daniel J. Shybunko in April of 1971. Dan was working as a structural Engineer at Grumman Aerospace at the time and received support from their leadership to open a small manufacturing company on Long Island that could function as a subcontractor for smaller structures. In 1978 Dan departed Grumman after 25 years of service and put all of his efforts into expanding GSE’s capability. GSE has demonstrated steady growth for over 50 years with a broad range of experience on numerous complex structures that support our military applications. Today, GSE is recognized as a national leader in the aerospace industry and has grown to be one of the largest federally certified Woman Owned Small Businesses in the Defense Logistics Agency for Aviation.
