ThompsonGas Continues to Grow


Successful propane companies don’t just happen. Success requires nurturing, year after year, to assure that customer expectations not only are met, but also exceeded. At ThompsonGas, we trace our beginnings back to 1946, the year Lloyd Thompson founded the 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.

ThompsonGas is one of the top 19 propane companies in the US. Family owned and operated since 1946, ThompsonGas provides propane services to residential and commercial customers across ten states in the East and Southeast. ThompsonGas has delivered fair propane prices consistently.

ThompsonGas is a company founded on the solid family operated business principles of trust and service, and deep-rooted values.

Today, 71 years later, we are proud to announce that ThompsonGas continues to grow, we have acquired the assets of Dallas County Propane, of Buffalo, Missouri from owners Lee and Monica Garrett, and Garrett’s Propane of Rogersville, based in Rogersville, Missouri from owners Mark and Shellena Garrett. Not leaving his business behind, we are thrilled to announce that Mark Garrett has joined ThompsonGas as manager of both operations!

ThompsonGas now serves more than 95,000 customers in 17 states (MD, VA, PA, WV, NC, SC, TN, KY, GA, AL, MS, FL, MN, WI, MO, WA, OR).

ThompsonGas COO, George Koloroutis: “These are our second and third acquisitions in the State of Missouri since 2016 and we are encouraged by the quality of the businesses that Lee and Monica and Mark and Shellena have built. Both transactions will provide an immediate contribution to our business and we are very proud to welcome their customers and employees to the ThompsonGas family.”
