NorthstarMLS is among the best operated regional MLSs in America. At the helm has been John Mosey, one of the finest executives you can find. Mosey’s passion for the work drove his desire to work much longer than his wonderful wife, Honor, preferred (although I am sure that she enjoyed sending him off to the office at times).

The Council of MLS has honored Mosey for his many accomplishments – far too many to list – but I have a very special place in my heart for the work that John Mosey has done on two fronts; one at home and one nationwide. At home, NorthstarMLS worked with fellow MLS executives across Minnesota and neighboring states to create a regional data share. It is an elegant and effective solution that provides practitioners with access to MLS records to better serve their clients without consolidation or mergers. The second is the work that Mosey did with Merle Whitehead. This team of MLS Executive + Broker Executive refined the Broker Public Portal and invested countless hours in making the BPP a success.

Standing on the shoulder of this giant will be Tim Dain. Tim and John have enjoyed a great relationship over the years whereby I witnessed Mosey coaching Dain, and Dain challenging Mosey on some issues. They have respected each other for many years and the participants and subscribers who will rely upon Dain’s leadership moving forward will find a kindred soul.

Thank you, John, and good luck Tim! We are certain that the passing of the baton will be flawless.
