Forty years of Cornerstone Interiors—and one evening we will not forget.
In 1986, Barbara Olmstead began the firm that would become Cornerstone Interiors. This summer, we gathered at the Columbia Club with clients, collaborators, friends, and family to celebrate four decades of design, relationships, and trust.
We are deeply grateful to everyone who has welcomed us into their homes, worked alongside us, referred us, encouraged us, and helped shape our story.
Cornerstone has always been committed to excellence and to people. Thank you for allowing us to continue that work for 40 years—and into the next chapter.
