KATIE KIERNAN
She represents buyers — sourcing on-market, off-market, and pre-market opportunities, and underwriting each property before a bid: construction quality, replacement cost, and what an asset is genuinely worth. She weighs what is rare, what will hold its value, and what a discerning buyer will pay for it years from now.
Aspen and Snowmass are among the most sought-after markets in the world, and the best property often trades quietly — here, representation is less about choice than about access. From ski-in/ski-out estates to contemporary retreats, Katie works with a few buyers at a time and stays close to every detail of the acquisition.

A lifelong Aspen local, Katie co-founded O2 Aspen in 2002, building one of the community's enduring wellness brands while developing deep relationships throughout the valley's business and philanthropic communities. Those longstanding local connections continue to provide clients with nuanced insight into Aspen's neighborhoods, lifestyle, and evolving market.
In 2005, Katie co-founded 212GALLERY, an internationally recognized contemporary art gallery that worked with leading institutions and artists, including Christie’s, The Andy Warhol Foundation for the Visual Arts, and Shepard Fairey. The gallery attracted prominent collectors from around the world and was recognized by publications including Art+Auction and The New Yorker. That experience cultivated trusted relationships within the global collector community and refined her understanding of discretion, provenance, valuation, and the expectations of high-net-worth clientele—qualities that naturally translate to luxury real estate advisory.
In 2007, Katie co-founded Aspen Luxury Brokers with her husband, combining her extensive local network with a personalized, relationship-driven approach to representing discerning clients entering the Aspen market. Her experience working alongside investors, wealth advisors, entrepreneurs, collectors, and business leaders enables her to navigate complex transactions while helping clients identify long-term real estate opportunities aligned with their broader investment goals.
Katie further expanded her expertise in 2014 as co-founder of TWYLA, an online art marketplace that raised $19 million from premier venture capital firms including GV (Google Ventures), IVP, and Redpoint. Successfully raising institutional venture capital and building a technology company sharpened her capabilities in high-stakes negotiations, capital formation, strategic marketing, and investor relations—experience that directly benefits clients making significant real estate investments.
For Katie, Aspen is more than a market—it is home. Having grown up in Aspen and chosen to raise her family there, she offers clients an authentic perspective on the community, its lifestyle, and the long-term value of owning property in one of the world's premier luxury destinations.
Katie also remains actively involved in the Aspen community through organizations including the Aspen Education Foundation, Aspen Aviation Club, Aspen Art Museum, and Anderson Ranch, reinforcing the local relationships and community knowledge that continue to serve her clients.
