It All Started in 1994
Butte, Montana
Propane Services Innovated was founded in 1994 by Sharon Quinn, Louie Laird, and The Town Pump Corporation. In 2001, Town Pump purchased the shares of both Sharon and Louie; Louie moved out of state, while Sharon remained as manager, providing leadership and continuity. In 2018, Timberline acquired the business and rebranded it as Propane Services Innovated, carrying forward its strong reputation for propane expertise. In 2021, ThompsonGas purchased the propane assets of Timberline Gas which included PSI Propane. PSI Propane has been a proud member of the ThompsonGas Family for almost 5 years!
