"Marcus did a great job coming up with various options to try to fit our needs and once we zero'd in on an option, he was great at negotiating with the lessor and us for terms that worked for both parties."

“Marcus was informative and kept us in the loop throughout the whole process, which made the transaction that much easier. We couldn’t have asked for a better agent!”

"Our firm, Yankton Area Progressive Growth, Inc., finished construction on a 40,000 square foot spec building in 2013. Soon thereafter we listed the property with a very well known national commercial real estate firm. During the following three years, the aforementioned real estate firm engaged with us on a very limited basis and followed up with only a few referrals. On a couple of potential client visits, the listing firm didn't even send a company representative to assist us in our showings. Needless, to say we were very disappointed and felt we needed better representation with a firm that was more engaged and had a better understanding of our local economic environment.
Yankton Area Progressive Growth was very fortunate to be introduced to Bill Connelly and through that initial meeting, we knew Bill and NAI had the necessary resources and referral network needed to assist us in the sale of our building. Bill was very knowledgeable about Yankton's political and economical dynamic and used that information to market our property to potential clients who were a "good fit" for our community.

Bill Connelly was very active in marketing our building on a local, regional and national level and who referred our site to several prospective clients. I must note that, for each and every client introduction and site showing, Bill was right by our side. In addition, Bill thoroughly researched his clients and provided us with very valuable information on each to assist us in determining how these prospective buyers would impact Yankton from an economical and social perspective.

Yankton Area Progressive Growth executed an agreement with NAI on September 17, 2016 and we were under contract for the sale of our spec building within ten months. It is for the reasons noted herein that I highly recommend Bill Connelly and NAI Commercial Real Estate Services. Bill has proven himself to be a highly effective and involved professional of the highest degree."

"Marcus is a true team player that puts client needs over his own! I had a tight timeline to find an office and not much knowledge of downtown office space and what I actually wanted or needed. However Marcus made himself available immediately and he quickly understood my needs, making them his focus. Even though the properties he was currently responsible for didn't meet my needs, Marcus made sure that NAI did by unselfishly connecting me with another team member who represented a more appropriate space. His market knowledge, willingness to collaborate, and focus on understanding/meeting client needs with urgency really simplified the process for me. I would highly recommend Marcus!"

"Jon is a team player and a pleasure to work with. Finding office space can be daunting, however Jon makes sure he understands/meets your needs in order to 'get it right' before just 'getting it done.' Despite the demanding timeline I had to work with, he was always available and made the whole process easier and more enjoyable. I would highly recommend Jon!"

"Thank you Marcus for your efforts on the sale of our property in Ipswich SD. NAI of Sioux Falls, and yourself, were a great team to help us with this sale. Everything was very professional, and the communication was superb. It is so nice to get answers when needed, and in a timely manner. We will certainly use you in our next need for selling one of our properties. I will not hesitate to refer you to anyone looking for help as well!"
