Two longtime friends and Steamboat Springs residents, Sierra Fallon and Katie Thornton, have teamed up to open a shared retail space in a historic building on Oak Street. The property at 434 Oak Street was recently listed for sale, and the pair saw it as an opportunity to combine their entrepreneurial dreams and deepen their decades-long friendship.

Why it matters

The opening of Fallon and Thornton's new shared retail space represents the continued revitalization of Steamboat's downtown core, as local business owners invest in the community's iconic architecture and collaborate to create unique shopping and dining experiences. Their story also highlights the power of long-standing friendships to fuel new ventures and contribute to the fabric of a small mountain town.

The details

Fallon plans to open a home goods and lifestyle store, while Thornton will operate a specialty coffee shop in the same building. The duo worked closely with local contractors to preserve the historic character of the structure while modernizing the interior to suit their needs.
