What People Are Saying About Marcus

"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."  

Keith Auch
Reclamation Technologies, Inc

"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

"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."

“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

“Our Church made a difficult decision to not build a new building but rather look for an existing building or space to remodel instead.  Finding an existing building or space to fit a church can be extremely difficult.  Marcus took the time to listen to the specific needs and wants of the church before attempting to locate properties.  That approached help narrow the search for him and helped us keep an open mind on the options presented.  In the end we found the right fit and Marcus made it happen.  We are very appreciative of Marcus’ thorough approach and professionalism.”
