Marie Leonard of Marie Lyall Interior Design has been a successful interior designer for over twenty years as a luxury boutique design and décor firm in the world-renowned Napa Valley.


Among many of her aspirations in her interior design firm are the relationships she cultivates and maintains with her clients. Marie enjoys the process and experience with each client and personally guides them through the entire design process from conception to the conclusion. She is a firm believer in virtuous communication for a successful working relationship and for the best outcome in achieving her client's vision through her interpretation and point of view. Marie is mindful of her client's committed investment and project time frame. She has a thorough understanding of keeping the character and integrity of a single room or multiple residential or commercial spaces, whether for an update, renovation, restoration, or new build. Her enthusiasm and affinity for meticulous detail permeate a sophisticated, elegant, sincere space within all her designs.     


As an entrepreneur with a creative and innovative mind, Marie's first endeavor in business was in the world of fashion as a principal owner of boutiques specializing in women's designer apparel for over twenty years. Customer service at a concierge level was of utmost importance, as well as developing long-term relationships with her clientele. Marie designed each location uniquely within the mix of each boutique

in Northern California. With her keen sense of color, selection of decorative surfaces, attention to architectural details, sensible space planning, and an eye for the task and ambient lighting, Marie transformed each boutique with a tasteful bespoke design.


Marie is inspired by her passion for homes and architecture from her earlier years and the surroundings of the local panoramic views within Napa Valley, expelling flavors of Italy, Spain, and France, not to mention California's distinctive architectural offerings. Her design inspirations derive from her incomparable surroundings and different eras, origins, and cultures.


Specializing in residential and small commercial interior design and décor, Marie's boutique firm has grown organically by primarily client referrals. She has had the opportunity to design multiple projects for her clients, such as residences, rentals, second homes, and businesses. These projects have taken Marie from Napa, Sonoma, Marin, and San Francisco to Los Angeles and Palm Desert. While creating cherished relationships with her clients, she also values collaborations with her team of builders, architects, craftsmen, artists, and other creative and talented members of her design community.

“We have worked with Marie on and off for several years, slowly remodeling and updating our home. We recently had some kitchen modifications completed and the look is fabulous. Marie has such a keen eye for color and works with existing colors in home to keep with the theme that suits our taste. We are so grateful to Marie and her team as they are knowledgeable and professional and have come up with some creative alternatives in modernizing our older home. Marie is simply the best in the business!."
