Leonard Auction, was founded by auctioneer and appraiser John Leonard in 2006. Our first auction house located in Naperville, Illinois opened May 1, 2006. The business grew rapidly and we quickly outgrew our space. This prompted our September 2007 move to our current auction house located in Addison, Illinois. Our 8,000 square foot auction house features ample display, office and warehouse space to serve our clients, estates and customers alike.
