From the very 1st time we talked with Aaron, we knew we picked the right auctioneer.  He listened to all our questions and concerns. He was so positive and he kept in touch with us thru the whole process.  Aaron and his staff went above and beyond our expectations!  They are awesome and we highly recommend Zielsdorf Auctions.  Thank you Aaron for a great job well done!

Dale & Debra Wussow



We couldn't have been happier with the service we received from Brandon and the entire staff at Zielsdorfs. Brandon was very accommodating with all our questions and concerns and even helped to haul some of our equipment to town! He gave us tips and pointers on how to best present the items to be auctioned off. The auction was successful and handled with extreme professionalism.

Lois & Joseph McGeary



From the beginning to the end, the entire Zielsdorf Team was exceptional.  Not only were they knowledgeable and professional but friendly and helpful.  They worked hard to make our sale successful.  We look forward to using them again for our next sale.

I was very satisfied with the service that Zielsdorf Auction provided for me in 2018. Their service was complete from the time that Aaron and I first had contact about a consignment sale through his follow-up after the sale. Aaron and Matt were respectful of me as the farm owner as well as respectful in how they handled the machinery and equipment that was to be sold. When I questioned if certain items would sell, they encouraged me to put them on the auction. I was very pleased with the financial outcome of the consignment auction. I will look to Zielsdorf Auction for selling more machinery and miscellaneous equipment in the future.

Vernon Vergin

Very professional from the day I entered the office until we finished the closing.

Adam Foslien

Excellent experience working with Aaron both selling and buying our homes. We will give him our highest recommendation.

Butch Berens

I very highly recommend Zielsdorf Auctions and Real Estate. They handled my online auction very, very well. I enjoyed working with them and watching the bidding online.

Heidi and David Lipps

Aaron was just taking over for Bob when we were closer to the auction time and getting ready so there was a transition for everyone. Aaron & Matt did a fantastic job of helping us through the process of getting things lined up for the sale. They are very hard workers! The pick up days went very smoothly and the rented dumpster was almost empty. With the load out assistance, junk was not left behind. They can be a fun group to work with as well as being professional.

Russ Barkeim, Kruger Farms

Aaron has a great team working with him, they did a fantastic job from start to finish. Great communication throughout. I was very surprised by the attention our auctions received and from many states around show their advertising program really works. The way they set it up and the quality detailed pictures gave everyone confidence in there bidding. Couldn’t be happier!

Patrick and Lacey Wersinger

Aaron was Amazing – Transaction went smoothy. Very helpful and pleasant to deal with.

Adam and Holly Kolander

Aaron was above and beyond helpful. The experience was positive because he helped walk through every step of the process. We can not thank him enough for finding us our new home.

Janice Braun

We, the family were selling our mother’s house and wanted to do so before winter. We hesitantly chose the route of an auction. I researched the services available in the area. I called Zielsdorf first and Aaron took the time to explain the process. He then answered every question I had. We agreed to meet at mom’s house with one of my brothers also. He was very professional as he toured the home and lot. Again he answered our questions and concerns. We signed there and then. He aggressively went to work advertising the house, holding multiple open houses. He also called multiple investors prior to the auction. The day of the auction many people showed up with SIX active bidders. We are very pleased with their every effort resulting in a price we are thrilled with. The closing paperwork is presently in process and will be completed before the end of the month. Our expectations were exceeded by their efforts. Thank you to Bob and a huge thank you to Aaron, your knowledge and expertise came through for us.

Ron and Jeannie Klimek

Aaron Olson and Bob Zielsdorf and the whole auction crew including the fabulous lunch wagon did an excellent job with our farm and real estate auction held on Nov.12, 2016. They not only have excellent knowledge and skills of the auction business but they also are the most compassionate friendly team to work alongside. Selling the farm or business is never an easy task emotional as well as physically they stood beside us all the way and were always available to answer questions and concerns. They really are number one in the business.

I was very pleased with not only the outcome of the auction but the overall process.  There were many things that I appreciated and I’m not sure if I’ll
remember to list them all. Aaron is very responsive and replied to all questions quickly. I felt I had a very good idea of the plan and what was happening throughout the entire process because of this. All of the workers that came to Montevideo were very professional and polite, many of them introduced themselves to me and shook my hand. It was clear that both Aaron and Brandon are educated about many of the items that were sold. I really can’t state enough how much I respect Aaron Olson and his work ethic. Overall I had a good experience with Zielsdorf Auctions.

Jon and Sara Reich

Selling our home of 14 years wasn’t an easy decision, but Aaron and Zielsdorf Auction and Real Estate made the process easy and helped us find the perfect home for our family. We definitely recommend Aaron and Zielsdorf’s to everyone for buying and selling. 


Riaz and Mary Aziz

Working with Aaron was a positive experience. He is professional, yet friendly. He kept us informed of what was happening with our property. He gave us good advice on our behalf. We would highly recommend him.

Tom and Christi Ahrndt

Aaron is professional, very personable and genuinely cares about the people he is working with. Aaron and the Zielsdorf Real Estate went above and beyond our expectations. We would not work with anyone else when it comes to our family’s real estate needs. Three generations of our family have worked with Aaron and Zielsdorf Real Estate over the past few years and we couldn’t be more pleased.

Rodger and Martha Molde

My wife and I chose Zielsdorf Auctions first for our business liquidation auction and then for our farm retirement auction after a recommendation from a friend. We were very happy and satisfied with the outcomes. The Zielsdorf team worked hard and fast to advertise, organizing, set up and sell our inventory and equipment at both auctions. We highly recommend them.

Ron and Rosemary Mills

Very courteous and kind! We liked the way our online only auction was handled. They showed our items in a very professional way.

Zielsdorf Crew, I can’t Thank You enough for such an excellent job with the Henry Ruter Estate. You have such a wonderful team and we appreciated all your nice help with our auction. I most certainly will highly recomment you to our family and friends. Thanks again.

Debbie Manske

Zielsdorf Auction agreed to do everything needed to prepare for the auction. They kept their promises and took care of everything. We didn’t have to do anything other than taking items that we wanted to keep. They made me feel at ease about the whole process. They cleaned the house and made it look spectacular. They cleared out the garage and sorted through hundreds and hundreds of tools and equipment. Then even
sorted through items in an old barn that was overflowing with stuff that I called junk. If they found something of value, or something they considered a “keepsake item”, they set it aside for us. Aaron and Bob were very friendly and kind. They treated everything as if it was their own, and this was their family they were taking care of.

Great job Aaron!!! I appreciate all your hard work.

Derek Nibbe

"We want to express our thanks to Zielsdorf Auction & Real Estate Services for all their advice and help in conducting our farm retirement auction. Thank you to Talon, Lane, Matt, and Brandon for all your work in washing equipment, organizing all the lots, and gathering information. You were great to work with, and we appreciated all of your work. Thank you to Aaron and Bob for your guidance and advice on putting the auction together. A
farm auction is something we had no experience with and will only do once in our careers so it was great to have your experience and expertise so that we could get it done right. We were very happy with how the auction was set up and conducted. Thank you very much!"

"We appreciated Aaron’s enthusiasm from day one. He helped us feel more confident in our decision to purchase a new home especially since we were moving from 2 hours away and needed to rely on him to keep his finger on the pulse of home availability in Benson. His knowledge of the area and community gave us an edge. We were able to find and work with a seller before they even put their house on the market in part because of the positive relationship he already had with them. He made it clear that he was our advocate and explained everything in terms we could understand. Aaron was extremely Receptive when I emailed, texted, or called which we greatly appreciated. Aaron was always one step ahead of me and 3 steps ahead of our mortgage broker. While we did have some slowness and timing hiccups with the mortgage company Aaron was assertive in his communications with them and relayed any information to us no matter how small right to the day of closing. Even with the issues, we had with the mortgage company Aaron was right there to the end to make sure that we were handed those keys on the closing date we wanted. I would not hesitate to work with Aaron Olson again as a home’ buyer and if we decide to sell in the future, I will also give him a call. Aaron’s enthusiasm, hardworking ethics, and knowledge of the surrounding communities is bar none. His realty knowledge and experience shone through. I will recommend him anytime someone is looking to buy or sell in the area."

Aaron Ringgenberg

"Zielsdorf Auction & Real Estate, particularly Aaron Olson, made our home sale, and relocation to Benson an enjoyable experience. Aaron is knowledgeable, patient,  and confident. His advice led us to the right home for us. I’d trust him and his team again in a heartbeat."
