Dean's Bulk Service is a regional distributor in the oil and gas sector, based in Barnesville, Minnesota, and established in 1969. It offers a full range of fuels, propane, and lubricants to its clientele. The business began when founder Dean Tonsfeldt committed to a two-year Amoco route around Comstock, Minnesota, and has grown with his wife Mae and their son Ryan at the helm.

Over time, the company has adapted to industry changes in branding and expanded beyond its original Amoco affiliation to include other major brands such as BP, Tesoro, and Chevron, while phasing out its barrel reconditioning activities. Propane has become part of its product mix. The company emphasizes safe, courteous operation as a core principle and aims to sustain its service for multiple decades into the future.
