Founder + Principal Designer
From a very young age, Sarita knew that she had an obsession with interior design and beautiful, stylish spaces. In 2014 Sarita launched her design firm – Sarita Simpson Design – and has since completed dozens of projects for both residential and commercial clients in the DC area. For more than seven years before that, Sarita was the lead designer (working with Jason Claire) at Vastu, a high-end furnishings boutique in Washington DC, where she designed residential and commercial spaces, including apartment model units and lobbies as well as custom furniture, rugs, and window treatments for her clients.
Addam joined Interior Matter in November 2022. From a young age, they knew they wanted to work in design, with interior design as the happy mix of their deep love of art and architecture. Graduating from The Art Institute of Washington with a degree in Fine Arts has prepared them for a career in interior design. They enjoy transforming a client’s needs and wants into reality. When Addam is not working, you can find them shopping (housewares and fashion), visiting museums, hiking, biking, and gardening. They and their husband recently bought a house in the Kingman Park area of northeast DC. Their Lemon Beagle, Teagan, sits on the arm of the sofa near a window and pretends to be mayor of their street.
Lindsey has been working in the design field for over 20 years, with completed projects in San Diego, Austin, Brooklyn, and New York City. She moved to the DC Metro area and joined Interior Matter in 2022. Lindsey is driven by a passion to care for people through the spaces they inhabit — honoring what has been entrusted to her while holding to the guiding principle that any work done, in order to be considered an improvement, must result in a space that is less burdensome, more efficient, higher functioning, deeply personal, and of course… beautiful. Although she admires those with diverse interests and balanced lives, her interests are singular – the spaces that humans inhabit and the storied lives we draw on to curate those spaces.
Having worked with Sarita since 2017, Hannah joined Interior Matter at its founding and assists on all projects from concept to construction. She is a graduate of the Corcoran School of the Arts at the George Washington University, with a BFA in Interior Architecture. Hannah has a passion for people; she loves that her work allows her to collaborate directly with clients to create spaces that are a reflection of themselves. A right-brained creative with a left-brained passion for computer science, she uses her dynamic skillset to bring our designs to life through plans, elevations, and 3D renderings. In her free time Hannah enjoys building computers, visiting art museums, and reading ridiculously long sci-fi novels.
