Our Mission

The mission of the Rocky Mountain Employee Ownership Center (RMEOC) is to build a more just and sustainable economy through employee ownership.

We believe that a just economy is one that works for everyone, that is built upon inclusive and sustainable systems, and that provides equitable opportunity to build wealth.  Our current economy benefits too few, at the expense of too many.  But employee ownership is a powerful tool to change that.

RMEOC’s founders understood the power of employee ownership when they launched the organization as a 501(3) nonprofit in 2012 – and we see growing evidence of it every day as we help more and more businesses become employee owned, creating wealth for working people, helping to close race and gender wealth gaps, and building more sustainable, resilient, and profitable businesses that provide long-term benefit to our communities.
