Meet Kerith

Kerith Flynn

Kerith Flynn is the founder and visionary behind Margali & Flynn Designs, with decades of experience and a degree in interior design and interior architecture from the Academy of Art. Her passion for design deepened while studying art history and design in Florence, Italy, where she developed a lifelong appreciation for timeless beauty and craftsmanship.

After co-founding the firm and leading it for over a decade, Kerith took sole ownership, expanding beyond traditional interior design into ground-up luxury home building and full-scale renovations. She has personally taken homes from concept to completion, as well as purchased and transformed multiple homes in need of restoration into stunning, high-value properties. This experience gives her a unique understanding of the importance of protecting a client’s investment.

Kerith knows that taking on a home project can feel overwhelming. With empathy, expertise, and a hands-on approach, she and her team bring clarity and confidence to every step of the process. The result? Beautiful, functional homes that reflect each client’s vision and stand the test of time.

“Everyone at Margali and Flynn is a pleasure to work with. They are knowledgeable, experienced and professional. We are doing a major renovation and the benefits of the cumulative years of experience is priceless. Keri and team are respectful of your budget and offer alternatives when you might veer off! They spend countless hours preparing for a meeting and since they take time to understand your style and preferences your time is well spent.”
