GDA Turns 30!

Today, GDA celebrates is 30th birthday. We’ve come a long way since our incorporation on November 21, 1978. What started out as a small 2-man consulting firm has become a full-service geothermal company serving clients around the world with a staff that has over 100 years of combined geothermal experience.

We look forward to continuing to expand and serve the geothermal industry for many more years to come!
