About Us


Leaving Our Mark

The Cornerstone Group is an award-winning real estate development team founded in 1993 by Colleen Carey in response to the Twin Cities community’s need for a variety of high-quality housing options.

Since its inception, The Cornerstone Group has specialized in urban redevelopment projects, as well as historic renovations of significant properties, creating over $200 million in housing and mixed-use development initiatives.

Here’s a quick look at some of the projects we’ve been fortunate enough to work on over the past 20+ years. If you’d like more details on any project, just ask.
