Thomas L. Woltz, Senior Principal of Nelson Byrd Woltz Landscape Architects (NBW), leads his firm in the artful creation and revitalization of public landscapes. Working at the intersection of culture and ecology for the sustainability of the public realm, Thomas has led the expansion of NBW to include scientists and historians as integral contributors to the design of projects ranging from restoration ecology in large urban parks to post-industrial sites and educational campuses. Through this collaborative and cross-disciplinary approach, NBW’s designs reveal lost or erased histories in the landscape. Thomas Woltz led the vision for Olana’s award-winning Olana Strategic Landscape Design Plan, which includes the recently opened Frederic Church Center for Art & Landscape.

Thomas was educated at the University of Virginia and holds master’s degrees in landscape architecture and architecture as well as an honorary Doctor of Science degree from the State University of New York, Environmental Science and Forestry in Syracuse. In 2011, Thomas was invested into the American Society of Landscape Architects Council of Fellows, among the highest honors achieved in the profession and was named the Design Innovator of the Year by the Wall Street Journal Magazine. He was also recognized as one of the most creative people in business by Fast Company and with the Land for People Award by the Trust for Public Land. Woltz currently serves on the Boards of Directors of the Cultural Landscape Foundation.
