Sullivan Expertise.
Trusted Since 1979.
Sullivan Auctioneers was founded in 1979 in Hamilton, Illinois — built on the principle that selling land requires honesty, local knowledge, and an unwavering commitment to the seller's best outcome.
Over four decades, that same commitment has guided every auction we've conducted. We expanded from Hancock County to cover auctions across Illinois, Iowa, Missouri, and beyond — always putting the seller first.
Today, the Sullivan team conducts 250+ auctions a year, selling thousands of acres of farmland plus farm machinery and collector cars. Sullivan Auctioneers, a Ritchie Bros. solution combines decades of local expertise with the reach and resources of a world-class auction network.
