Early Career
Katie’s career spans luxury real estate, blue-chip art advisory, and entrepreneurship, giving her a rare cross-disciplinary perspective valued by sophisticated collectors and investors.
She co-founded O2Aspen, a long-standing wellness destination in Aspen, and later established 212GALLERY, where she built a dedicated team of advisors working with collectors and artists from around the world.
