Jill Jones
Jill JonesChief Operating Officer
Jill co-founded the company with Warren Rogers in 1979. She is a true pioneer in this industry, having developed the first reliable means of predicting when underground steel fuel storage tanks would fail. That method is so reliable, it’s used in more than 25,000 gas stations in the United States, Canada, the United Kingdom, Japan, Central America and Australia. Jill’s expertise, combined with advances in automation and communication technology, led to the creation of our Continual Reconciliation Analysis to monitor and analyze fuel inventories at some of the most active fuel sites in North America.
