More than 20 years of
real estate excellence

Our Beginnings

It all started back in the Summer of 2002 when John Raddatz was called in to assist Coldwell Banker and The Cornerstone Group with sales and marketing for a mixed-use development in Richfield, MN.  Kensington Park would later become a 96-unit, 4-story project, blending residential condos with 27,000 square feet of ground floor retail space.

The experience of being on site at Kensington Park inspired John, who saw the opportunity to provide strategic assistance for companies pursuing their development goals. From sales and marketing to finance, design and build, it would always come down to assembling the right “ingredients” - to create the perfect stir.

Our first “Second Call”

Stir, LLC was officially formed on May 8, 2004, and soon after, received its first “Second Call” - setting our standard of excellence right from the start. The Cornerstone Group selected Stir as their construction coordinator alongside JE Dunn Construction for a new multi-family development called The Mist on Lake Minnetonka. 

Financed by Prudential and designed by Cuningham, this $41M, 116-unit, 3-story project came into turbulent times, marked by declining condo sales. It was an important early test for Stir that paid off in the end, with The Mist on Lake Minnetonka becoming a very successful market rate apartment building.
