Interior Designers & Decorators

About Us

There is no doubt that creative design is in Keith Mazzei's DNA. Having graduated from the Metropolitan Institute of Design, one of the country's oldest and most established accredited interior design schools, Keith rewed up his creative engine in the field of retail design and interior design with other firms before deciding to devote his energy to his own design enterprise. Since then, Keith has burnished his two-decade career as a sought-after designer working in close concert with architects, builders and contractors, quite often from the infancy of the project by carefully learning every personal, lifestyle and structural requirement of his clients' interiors - including space planning, selection and installation of fixtures, finishes, furnishings and custom built-ins - all the way to each project's timely and stunning completion. Specializing in both modern and traditional interior design styles, Keith loves ground-up construction, home renovations and home design. He explains his professional style very simply - he is often the first person into a project and the last person out, after taking care to adorn each space with just the right art and accessories. And he does all of this with a very critical eye and a highly effective managerial style that is attuned to all contingencies. With residences in both Long Island and South Florida, Keith handles projects from Manhattan to Montauk (NY) and Miami to Manalapan (FL). He is a member of ASID and recently joined the Designers + Builders Alliance of Long Island. He may be reached at 516-729-2858 or at
