Company Information

Leonhardt Auction Company, Inc. has been helping buyers and sellers connect since 1980. Founded by Leonard E. Miller, the company was built on honesty, hard work, and a simple belief that auctions should be straightforward and fair. Leonard dedicated nearly four decades to the business before retiring in 2018.

In 2023, his son, Jason Miller, stepped in to carry on the tradition. While times may change, the values that guide our work remain the same—respect for our clients, dedication to the process, and a commitment to making auctions accessible and successful for everyone involved.

We’re licensed in Illinois, Indiana, and Wisconsin and also conduct auctions in Iowa and Missouri. Whether you’re selling real estate, equipment, antiques, or personal property, our goal is to provide a reliable and professional service while keeping the auction process simple and effective.

At Leonhardt Auction Company, Inc., we understand that auctions aren’t just about selling—they’re about people, trust, and finding the right buyer for every item. We’re grateful for the opportunity to serve our community and look forward to helping with your auction needs.

If you’d like to learn more, we’d be happy to talk. Let’s make your next auction a success together.
