Alan Greenberger’s 42-year career has three significant chapters. For 34 years, he was a practicing architect with Mitchell/Giurgola Architects and its successor, MGA Partners, where he was the design lead on many award-winning projects. In 2008, Mr. Greenberger left his practice to join the administration of then-Philadelphia Mayor Michael Nutter as the city’s Chief Planner and then Deputy Mayor for Economic Development. Under his leadership, the City produced a new zoning code and comprehensive plan and continues to experience its most dynamic growth in half a century. Following the end of the Nutter administration, Mr. Greenberger was appointed Distinguished Teaching Professor and Lindy Fellow at Drexel University, where he serves as Department Head to programs in architecture, interior design, urban strategy and research.
As a practicing architect, Mr. Greenberger was the principal designer on several notable projects, among them: The Department of State’s National Foreign Affairs Training Center, West Chester University School of Music and Performing Arts Center, Lehigh University Linderman Library Renovation and the Philadelphia Salvation Army Kroc Corps Community Center.
In his dual role in city government, Mr. Greenberger oversaw the integration of long-range strategic planning with implementation of both business and real estate development goals. Under his leadership, the City of Philadelphia rewrote the Philadelphia Zoning Code and initiated a five-year long comprehensive plan for the city, entitled Philadelphia 2035. Both initiatives are the first of their kind for the city in over 50 years, receiving the American Planning Association’s National Excellence Award for a City Planning Agency in 2016. Mr. Greenberger's office also launched multiple programs to attract and support a burgeoning entrepreneurial community, called StartUpPHL, and was successful in attracting new, technology and venture capital firms to Philadelphia, in addition to expanding business opportunities for small, minority and women-owned businesses throughout the city. In 2015, he was the lead public figure in securing a World Heritage City designation for Philadelphia, the first American city to do so. In recognition of his efforts on behalf of Philadelphia, the American Institute of Architects honored him with its 2017 Thomas Jefferson Award for Public Architecture.
Now at Drexel University, where he was an Adjunct Professor for many years during his time in professional practice, Mr. Greenberger has overseen the expansion of legacy programs in architecture and interior design as well as the creation of new graduate programs in research and urban strategy.
