Mark Cunningham established his eponymous design firm in 2005, following a fifteen-year tenure at Ralph Lauren. Today, the firm's curriculum vitae is diverse in scope and scale, comprising luxury residential interior projects, hotel design, architectural consulting, and commercial concepts domestically and abroad. Soft-spoken yet meticulous, Mark has come to be known for his masterfully layered interior compositions and singular approach to space and style. Mark and Mark Cunningham, Inc. are honored to be routinely included in the yearly lists of America's top designers by Elle Decor, Architectural Digest, Luxe Magazine, and others.

In 2019, Mark launched MARKED. Now available to the design community, MARKED is a furniture line of select favorites from Mark's archival portfolio of custom-designed pieces, a project-minded textile collection, and a curated selection of vintage and found objects and art. The MARKED showroom shares an open and airy, sun-drenched space in midtown Manhattan with the Mark Cunningham, Inc. offices and is available to visit by appointment. The textile collection is available at Alt for Living in New York City and Los Angeles.
