Our philosophy is that successful projects require strong design and effective execution.

Many firms are skilled in either creative design or project management, but few excel in both. That’s where we differ. In other words, the MADGI team believes that product and process are equally important. Through every phase of a project, we integrate aesthetics into the practical demands of budget and schedule, providing a comprehensive service that connects ideas to results.


Montroy Andersen DeMarco (MADGI) was founded in 1990 by Dan Montroy, AIA and Steven Andersen, who first met in Italy during a study program at the American University of Rome. In the late ’80s, Dan offered Steven the opportunity to join him in creating a new firm. Steven agreed, and Montroy Andersen was born.

In 2005, with demand for the firm’s style of service growing, Dan and Steven joined forces with fellow NYIT graduate Richard J. DeMarco, AIA who became the third principal. A veteran architect who was then an associate partner at SLCE Architects, Richard enabled the studio to expand its new buildings practice.

Today, as Montroy Andersen DeMarco, the firm employs over 35 person staff and continues to expand. But the early days have had a lasting effect on the firm’s operations. “As principals, we don’t view ourselves as figureheads,” says Steven. “We started from the bottom and did everything ourselves, and we’re still intimately involved in each project. That just happens to be the way we do business, and it’s also why our clients come back to us again and again.”


As WELL Accredited Professionals and a member of the U.S. Green Building Council, Montroy Andersen DeMarco is a strong supporter of the organization’s mission:   “To transform the way buildings and communities are designed, built and operated, enabling an environmentally and socially responsible, healthy and prosperous environment that improves the quality of life.” 

In keeping with this objective, we offer a wide range of services related to sustainability in general and specifically to WELL and LEED (Leadership in Energy and Environmental Design), the Council’s green building rating system.  These services include guidance for and achievement of LEED CI (LEED for Commercial Interiors) and LEED NC (LEED for New Construction) certifications; recommendations on green materials, furniture, finishes and lighting; and consultancy on and creation of sustainable designs.    We continuously focus on creating buildings and workplace environments that advance and improve the health and human experience through design.

Principal Involvement

First-hand principal attention to each commission is still a key element of the process. This attention has enabled the firm to develop a group of legacy clients who speak for the firm.

After studying in Italy at the American University of Rome and receiving his Bachelors of Architecture degree from the New York Institute of Technology, Dan was employed only a few years in the architectural industry before he became inspired to start his own business. Working closely with his friend and fellow NYIT graduate, Steven Andersen, he has since built a legacy in MADGI. Dan’s love of the industry remains evident in his continued desire to improve both his company and himself.

Certified by the National Council of Architectural Registration Boards (NCARB) and a Registered Architect in New York, Connecticut, Florida, Georgia, Massachusetts and Washington D.C., he encourages his employees to continually enhance their skills through learning. With more than 25 years of experience, Dan specializes in the design and management of office, entertainment, residential and mixed-use projects and in turn, cultivates this ability in his firm.

Steven Andersen
Born into a construction family, Steven has nurtured a love and knowledge of design throughout his life. It is this love that led him to study the art of architecture in Italy, at the American University of Rome, to receive his Bachelors of Architecture degree from the New York Institute of Technology, and ultimately to create an architectural and design firm with his long-time friend, Dan Montroy. He has spent 29 years honing his abilities in the corporate interiors world, with a particular affinity for fragrance and cosmetics office, laboratory and showroom space. Steven harbors a deep respect for all things creative, and nurtures this passion in his firm – not only in sharing his love for music, art, architecture and design with those that he works with, but through his innate ability to encourage a curiosity that pushes the limits of creative thought.

After studying abroad at the University of Milan and obtaining his Bachelors of Architecture degree magna cum laude from the New York Institute of Technology, Richard proceeded to earn his more than 32 years of architectural experience, spending 20 of these working to become an associate principal at SLCE Architects.

A Registered Architect in both New York and New Jersey, Richard’s great attention to detail has buttressed his passion for building and honed his specialization in the design and construction of new and altered buildings of all types. In 2005, when approached by two of his NYIT friends and fellow graduates, Richard left SLCE and brought his attention to detail and his new building practice to Montroy Andersen DeMarco. His work has since continued to span the gamut of the architectural practice, elevating his firm to a full-spectrum practice.

Dedicated Team

The principals are listeners and focus on achieving a client’s vision. Those qualities have penetrated the firm at all levels, creating a client focused group of professionals.
