Creating The Essence of Home
Welcome to Theo & Co., a boutique interior design studio serving clients in Chevy Chase, Maryland and the Washington DC metro area. Known for our relaxed, yet refined aesthetic, we design spaces that are as warm and inviting as they are sophisticated. We infuse each home with depth and character, incorporating details that reflect your personality and tell your story. It’s the details – collected mementos, meaningful artwork, and family heirlooms – combined with a thoughtful, functional design that creates the essence of home.

"My husband and I have used Theo & Co. Design for several rooms in our house over the last few years. In all instances, Diane was able to quickly understand the aesthetic we were hoping to achieve and presented us with several choices for how to redesign our rooms. We appreciated how stress-free she made the whole process, from presenting us with visuals, providing us with plenty of price points and purchasing options, and completing the look with finishing touches — we couldn’t have been happier with our final rooms. We are already looking forward to working with Theo & Co. again in the future!"

CHARM, CHARACTER & A WALKABLE LIFESTYLE
Chevy Chase is a historic community just north of Washington, DC, where timeless charm meets everyday convenience. Tree-lined streets, many with classic brick sidewalks, create a welcoming sense of place, while beautifully maintained homes (from Craftsman bungalows and Cape Cods to Colonials and thoughtfully updated modern residences) reflect the area’s rich architectural heritage. With nearby shops, cafés, and restaurants all within an easy stroll, Chevy Chase offers a gracious, walkable way of living. Bordering Rock Creek Park and its winding network of trails, the area provides a natural retreat for biking, hiking, picnicking, and quiet afternoons outdoors. It’s a community that balances history with comfort, offering both character and livability. It’s an ideal backdrop for interiors that feel refined, collected, and deeply personal.
From lunch at Clyde’s of Chevy Chase to browsing antiques at Sloans & Kenyon or discovering art at Merritt Gallery, there’s endless design inspiration close at hand. I love spending an afternoon searching for hidden treasures at the nearby Kensington Antique Gallery, and on beautiful spring or summer days, nothing compares to time spent in Rock Creek Park, followed by dinner at La Ferme, where French cuisine is served in an elegant, country-farmhouse setting.
