Rob Pressman, ASLA


Over the course of his 35-year-career in landscape architecture, Rob Pressman has worked on five continents, designing a wide range of thoughtful, site-specific projects in Los Angeles and Jerusalem, Shanghai and Shenzhen, Melbourne and Monrovia (Liberia).

After obtaining a Bachelor of Science in the Conservation of Natural Resources from the University of California at Berkeley, and a Master in Landscape Architecture from the Harvard Graduate School of Design, Pressman set off for a decade, working on campus plans in Africa, open-space designs in Australia, and cultural landscapes in Israel, where he won Third Prize in a design competition for a memorial at the Yad Vashem Holocaust Memorial in Jerusalem. Other notable projects in Israel include a Pilgrim’s Way Station along the Via Dolorosa at St. Stephen’s Gate in Jerusalem, and the archaeologically sensitive conversion of Sultan’s Pool, a 2,000-year-old reservoir, into a modern amphitheatre.

Pressman returned to the United States in 1984, where he worked on large-scale urban projects with EDAW, Inc., in Irvine, California, turning his focus to the design of large master-planned communities and residential projects when he joined the L.A. Group, Inc., in 1986, as a Principal.

Pressman opened his own firm, TGP, Inc. in 1994, with a focus on high-density, multi-family residential and mixed-use projects.

Whether designing a residence on a challenging site in Los Angeles, or a large housing development in Shanghai, Mr. Pressman responds to the project’s individual challenges and characteristics, creating a distinctive product that takes into consideration both the setting and the culture.
