Gary Henderson founded Premier Geothermal in 2005. Geothermal Products was originally a sub-company under the Premier Geothermal Brand. In 2006, though, Geothermal Products became the sole company due to DIYer and small- to mid-size contractor needs. We focused our services to include the top sales, consulting and customer service of geothermal heating and cooling products. We stay closely involved with the National Ground Water Association (NGWA) to keep up-to-date on the latest technologies and industry best practices and to share our insights with the geothermal community as well.
Gary Henderson, founder of Geothermal Products, first became involved in the geothermal industry in 2001. He got involved because he saw a need in a new industry. Since, Gary has progressed through his career with lots of factory training and hard work. Gary became the National Ground Water Associations first-ever Certified Vertical Closed Loop Driller (CVCLD) in the nation. He also served as chairman of the NGWA’s geothermal committee for two terms.

Geothermal Products headquarters is in Ankeny, Iowa, but we have nation-wide reach. Being located in Iowa, we put geothermal heating and cooling to work around the year in some of the coldest and some of the warmest temperatures.
