Founded 1946

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 six decades with a commitment to service and a reputation for strong family values.
