Mendelson Group was incorporated in 2003 by its principal, Gideon Mendelson. A graduate of both Columbia University with a degree in Architecture and The New York School of Interior Design, Gideon brings a classically based, yet fresh and modern aesthetic to his projects. Focusing efforts on interior architecture and decoration, Mendelson Group’s goal is to create functional, comfortable spaces that are not only aesthetically pleasing, but also timeless in design, youthful and energetic.


Since its founding, Mendelson Group has been involved in the architecture and interior design of numerous projects in Manhattan, Westchester, Miami and the Hamptons. While our projects are diverse in both scope and design, a single principle is our constant guide: from the initial consultation, through architectural and decorative planning, to construction and installation, the client’s satisfaction is our first priority.
