Founded in 1996 as Kaufman Segal Design, our firm has been shaping elegant, functional, and enduring interiors for nearly three decades. In 2025, we proudly became Kaufman Segal Angyus Design to reflect a new chapter in our story—when longtime team member Lindsay Angyus was named Principal and CEO, joining founders David Kaufman and Tom Segal in leading the firm into its next generation. In 2026, the firm rebranded as KSA Design Group to better represent its dynamic future while honoring its longstanding legacy of design excellence.

Over the years, we’ve witnessed a remarkable transformation in the design industry. Today’s clients have unparalleled access to resources—from once-exclusive showrooms and design publications to countless online vendors. But with so many choices, the challenge isn’t finding options—it’s knowing which ones are right.

That’s where we come in.

At KSA Design Group, we guide our clients through the overwhelming abundance of design possibilities to create interiors that are distinctly personal, effortlessly functional, and timelessly elegant. Whether designing a family home, a corporate office, or a hospitality space, our work is grounded in thoughtful listening, deep expertise, and a shared passion for beautiful, livable environments.

We proudly serve clients in our hometown of Chicago and across the globe.

Great design should look beautiful—and feel right. Each space should express the personality of the people who live or work there, while functioning seamlessly for their needs.

Our signature approach blends classic sophistication with modern versatility. A traditional living room might feature iconic mid-century furnishings paired with bold color and antique accents. A law firm’s office may incorporate art that reflects its creative clientele. Every design choice—whether a custom-crafted cabinet, hand-scraped floor, or ready-made furnishing—is guided by purpose, comfort, and authenticity.

We’ve refined our collaborative process into ten clear steps, ensuring transparency, creativity, and precision from the first conversation to the final installation. To learn more about our design process for both commercial and residential spaces, go to Our Approach page.

“Each room and its pieces should be beautiful—but if they don’t work for how people live, entertain, or work there, none of the choices are right,” says Tom Segal.

Working with a design professional should feel liberating, not intimidating. At KSA Design Group, we make the process enjoyable, stylish, and efficient—helping you make confident decisions and create a home or workplace that truly reflects you.

Whether it’s a single room, a complete residence, or a commercial space, we’ll help you bring all the pieces together into a cohesive, timeless whole.
