ThompsonGas Company History

A Long History of Satisfied Customers

Successful propane companies don’t just happen. Success requires nurturing, year after year, to assure that customer expectations not only are met, but also are exceeded. At ThompsonGas, we trace our beginnings back to 1946, the year Lloyd Thompson founded our company in Boonsboro, Maryland. We’ve served that small farming community for over seven decades with a commitment to service and a reputation for strong family values.

Today, ThompsonGas is one of the top 10 propane companies in the US. ThompsonGas provides propane services to residential and commercial customers nationwide, and has delivered fair propane prices consistently.

ThompsonGas is a company founded on the solid family operated business principles of trust and service, old-fashioned values that never grow old.
