Philip C. Steiner, P.E.

Principal, Managing Director

Philip Steiner has been in practice for almost 40 years, and with Altieri since 1989. He received his Master of Business Administration from Pace University in 1990 and his Bachelor of Science in Mechanical Engineering from Rensselaer Polytechnic Institute in 1980. His expertise is in the design of special systems serving highly controlled, architecturally challenging environments with a particular focus on conservation environments. Phil has directed many of the Altieri’s signature projects including design of the central plant for The Getty Center and mechanical systems for the Getty Museum, total systems design and engineering for the renovation and expansion of the Museum of Modern Art, and the recently unveiled Gehry-designed renovation and expansion of the Philadelphia Museum of Art.

For many years, Phil lectured in Systems Integration at Yale University’s Graduate School of Architecture and on building systems as part of the AIA Connecticut Architect Registration Examination (ARE) review. He has taught Environmental Design at Yale, served as a panelist on the New York State Council of the Arts grant committee, and is a past director and Building Committee member at both the Darien YMCA and the Neighborhood Music School in New Haven, CT. He is a member of the Strategic Advisory Council for the Department of Mechanical, Aeronautical, and Nuclear Engineering (MANE) at Rensselaer Polytechnic Institute.
