What People Say About Us

The team at NAI Sioux Falls works to provide value to their clients at every stage of their transaction. Read what some of our clients have to say about our approach.

“I had been searching for the right office for my small business for several months and had worked with a few different property management companies without any success. That was until I worked with Marcus [Mahlen]. Marcus took an entirely different approach from other commercial real estate brokers and took the time to precisely understand what our needs were and provided an office solution that exceeded my expectations. What is more, Marcus made the entire process of leasing an office space straight forward and effortless. I could not recommend Marcus and NAI highly enough." 

Nathan Fredrickson
EPI - Director of Investigations & Risk Management

"As a church we have very specific needs, strict budgets, and lots of red tape to get through when it comes to real estate transactions. Marcus and NAI were phenomenal every step of the way - they were patient, easy to work with, and got things done promptly. We couldn't have had a better experience."

"Thank you for your assistance with locating available office space in Sioux Falls for our company. Your local knowledge led us to a great space and negotiations with the landlord were efficient and beneficial to KLJ. We greatly appreciate your services and connections in the community which helped us identify and open an office in less than 60 days!"

"When it comes to real estate deals, my office was small potatoes. Even though the deal was not big, and the negotiations were a little tense, Marcus was cooler than a trillion ton iceberg and got the deal everyone was happy with."

Josh Tordsen
Gigastrand Technologies

"We needed a specific type of warehouse space, Marcus continued searching until he found one that worked for our needs. He is a true professional."

After listing with other commercial realtors, on and off for a couple years, Dale Zomer stopped in the office and visited about listing our property in Sioux Falls, with him and NAI. We decided to give him a shot and see what he could do. Dale produced several offers and a buyer within 60 days. He was very professional and was able to close the deal without a hitch. We would use his services again, in a heartbeat.

"I was very happy with the service Dale provided in the purchase of CBY Storage Units! Dale's expertise and professionalism were great! Dale helped a great deal in this transaction and there were certain aspects of the business that he helped me understand much more clearly! I would recommend Dale Zomer of NAI Sioux Falls to anyone looking to work with a Broker who will go the extra mile, because he will. Thanks again Dale for your professional service."

Dale Zomer recently sold a commercial building for my husband Doug. We were very pleased with the way Dale took control of this sale as we were both nervous and unsure as to whether we were making the right decision. Dale was confident and assured Doug and myself that this would turn out great and he was right! I would recommend Dale to anyone trying to sell a commercial property.

On a more personal note we had a great time at the Rush celebrating the sale and Doug now refers to Dale as "Rookie of the year." It was great working with you and when we are ready to buy again we will be calling NAI because it was great working with you. Thanks again for all you did to make this happen.
