Geosco began in 1937 by Mr. Wolff and was located in Houston, TX. In the late 1950s, Geosco moved to downtown Houston. After 50+ years of growth, on November 1, 1993, the Hartzog family purchased Geosco from the Wolff family with an eye on the future.
In order to better serve our customers and expand the warehouse space, in 1998, we made a move to our current location at 12021 Brittmoore Park Dr but we haven’t rested on our past accomplishments. In 2011, more space was added to accommodate increased inventory, and allow for a new electronics assembly area and a chemical storage room. Our warehouse now boasts over 20,000 square feet of space.
