Our Story

"I'm Sold"

At Coldwell Banker Mason Morse Real Estate, we have reason to reflect on our past and focus on our future. When Bill Mason and Edward “Wendy” Morse opened the doors of their entrepreneurial real estate office on the corner of Hyman and Galena in downtown Aspen, Colorado, they aspired to establish a company founded on the principles of enthusiasm, integrity and service. Following that tradition, Ajax Holdings led by CEO Brooke Peterson, continues to build upon these enduring principals. Today, over a half century later, Coldwell Banker Mason Morse has grown to include more than 100 agents in six offices up and down the Roaring Fork Valley. We strive to fulfill our mission by working together in a climate of trust, dedicated to the people and communities we serve.


Coldwell Banker Mason Morse is the top-ranking real estate company in the Roaring Fork Valleywith a solid reputation as “The Source” for your real estate needs.
