Our companies

Welcome to GDT Advantage, we are businesses owned and run by the members of the Gonser family from Minnesota and Florida.

About GDT Companies

The Gonser family began with industrialists Tom and Valerie Gonser, some of the country’s first pioneers in the solar industry who enjoy working to preserve the quality of the planet. They have since passed on this entrepreneurial eco spirit to their sons John, Michael, and Jim Gonser. Michael and Jim Gonser of GDT Marketing have worked with industry leading waste management companies for many years, expanding their bottom line through creative customer acquisition solutions. The Gonser family continues to grow companies venturing into carbon offset services and footprint reduction solutions, trash, and valet services for apartments, HOAs, and real estate ventures. Through this, they intend to improve the quality of life for all of their customers while continuing to pursue cutting-edge, environmentally friendly initiatives. The Gonsers currently operates in Minnesota, Colorado, Kansas City, and Southwest Florida.
