Through his visionary work as the leader of Liberty’s urban development team, John Gattuso has changed the face of Philadelphia’s skyline and helped the city to reimagine its limitless possibilities.

The Comcast Technology Center, the Comcast Center, the ongoing redevelopment of the Philadelphia Navy Yard and the Camden Waterfront; all of these iconic projects were developed under John’s guidance during his 30-year tenure at Liberty Property Trust, one of the nation’s largest real estate investment trusts.

During that time, John was responsible for the development of over 50 projects in Philadelphia and across the nation, representing almost $3 billion in investment. His projects include the TJX Distribution center in Northeast Philadelphia, recognized as a “Smart Growth” development by the Sierra Club; the Plaza at PPL Center in Allentown; and the spectacular Comcast Center that became Comcast’s international headquarters upon completion in 2008, both recipients of the Urban Land Institute’s Award of Excellence.

His most recent work consists of the 1,121’ tall, 1.8 million square foot Comcast Technology Center which features a five-star Four Seasons Hotel, the tallest hotel in North America; as well as the new waterfront headquarters for American Water.
