Ann Wood Gregg, AIA, Partner

Before forming StudioGregg Architects, Ann established her own design and architecture firm with a focus on both historic and contemporary residences. Prior to this, she was a project designer with architects French & Crane, and Ann Ledger, renovating and enhancing local residences.  Ann also served as a consultant architect for Stenton, the historic Germantown home of colonist James Logan, and for the Center City Philadelphia headquarters of the NSCDA, a prominent women's organization.


Ann established her career designing corporate interiors in Manhattan after her graduation from Duke University.  As a project designer at Swanke Hayden Connell Architects, she completed large office interiors for Shearson/American Express, Salomon/Lehman Brothers, and Marsh & McLennan.  Upon returning to the Philadelphia area, Ann expanded her architectural expertise to include residential and institutional design.  Ann combines her strong background in interiors with an interest in restoring, upgrading and enlarging older buildings and homes.


In addition to a Bachelor of Architecture cum laude from Temple University, Ann holds a Bachelor of Arts from Duke, and an Associates in Interior Design from Parsons School of Design.  She has been a visiting design critic at Moore College of Art and is a Registered Architect in the Commonwealth of Pennsylvania.
