About Us


Kathy Marshall has been designing bespoke kitchens, baths and interiors for over 25 years. Her extensive product and design knowledge have been accumulated by working on projects all over the globe. In the early ’90s Kathy started a successful outerwear company, Mountain Ingenuity, where she designed and produced products for iconic brands such as Ralph Lauren, Brooks Brothers, and L.L Bean. Always a student of design and architecture Kathy and her father, Ed MacDonald, started a very successful Kitchen and Bath design firm on the South Shore of Boston, MA.


When her father retired, she decided it was time to blend her love of old homes, antiques, textiles, travel, and architecture into her own firm, Kathy Marshall Design, Inc., on the North Shore, in Wenham, MA. A critical eye for detail and depth of knowledge of renovation and restoration has earned her frequent spots on the acclaimed PBS show, “This Old House.” Recently she was featured on an episode on New England Living TV, CBS. Kathy has been featured on numerous publications regarding design and recently was featured in House & Garden UK. From the distinctive, traditional designs of the Northeast to the open, rustic beauty of some of the finest homes and kitchens in the West, Kathy has been commissioned to design consult on homes across the globe. Her innovative and family-focused designs and use of custom cabinetry, furniture, tile, textiles, and antiques have not gone unnoticed by national publications and design awards.
