The firm of RMG Associates was established by Mark Mustacato and Frederick F. Grippi, AIA Architects over 30 years ago, after working for years with Pierre Richau.  The majority of our work has been in custom residential design, with projects ranging in size from small additions to large scale homes.


We strive to ensure that each project reflects our clients’ personality and needs in a manner that is unique and graceful, focusing on each projects functionality and harmony with its surroundings.
