I would like to recommend GSS, I have worked with them for several years. The service is fantastic and everyone is so friendly. GSS was able to get me an item that was not on their website and deliver it the next day.

I have worked with Greg Modica and Government Supply Service (GSS) since in inception. This Veteran/Minority owned company has worked diligently to develop prompt, professional and price competitive services, providing a multitude of products. In just a few years they have grown to become not only a company I rely on for products but are now relied on by buyers across the country. GSS is fast becoming the vendor of choice for those companies wanting quality service and products. Thank you Greg for your dedication to excellence.
