Fluent in both interior design and construction, Sims Mackenzie Design Group is trusted by high-performing executives, entrepreneurial families, and industry leaders to design high-end family homes that offer rest and reprieve.
At the helm are co-founders Toni Sims and Kelsey Mackenzie, two distinct yet deeply aligned voices in the world of high-end residential design. Toni, a respected industry force with over two decades of experience, is known for her deep construction knowledge and long-standing relationships with Florida’s top builders and architects. Kelsey represents the next generation of design leadership—fresh, strategic, and deeply personal.
Together, they offer a rare blend of vision, precision, and leadership that few firms can match. Their nationwide portfolio spans custom new builds, large-scale renovations, and legacy vacation homes —each a seamless expression of their clients. Over the years, they have been quoted, interviewed, and featured in The New York Times, The Wall Street Journal, and Luxury Home Quarterly.
