Founded on a simple idea: offices should work as hard as you do.
Jeff started Sumner Furniture & Design in 2013, trading financial advising for a more creative path. Today the company serves businesses across DC, Maryland, and Virginia with new and pre-owned furniture, installation, and full design services.
