Originally from Winnetka, Illinois, just outside Chicago, James Stewart-Moore is a broker with Aspen Snowmass Sotheby’s International Realty who brings a thoughtful, development-informed perspective to real estate in Aspen and Snowmass Village. James earned both his bachelor’s and master’s degrees from the University of Colorado Boulder before building a career at the intersection of real estate, design, engineering, and development.

Before transitioning into brokerage, James spent nearly a decade as a partner at an engineering firm in coastal California, where he worked closely with leading architects and design teams in Laguna Beach, Newport Beach, Pacific Palisades, and Malibu to plan and deliver high-end residential homes. That experience gives him a uniquely practical lens on property - helping clients understand not just what a home is today, but what it can become.

In 2025, James contributed to more than $119M in residential sales while working alongside one of Aspen Snowmass Sotheby’s leading teams. Today, he works with families, investors, and developers throughout the Roaring Fork Valley, advising on purchases, sales, and long-term strategy across residential, commercial, and development-driven opportunities.

In addition to brokerage, James actively works on development projects within the valley as a partner, giving him a current, practical understanding of land use, construction feasibility, entitlement considerations, and long-term investment strategy. His background allows him to guide clients through important decisions with clarity - whether evaluating a home for livability, understanding renovation potential, or assessing future value.

James believes real estate in Aspen and Snowmass is deeply personal as well as financial. Whether helping a family find the right home base in the mountains or advising on a development-focused acquisition, he approaches every relationship with discretion, care, and a long-term perspective. His goal is simple: to provide thoughtful guidance, strong advocacy, and a level of service that earns lasting trust.
