Pfeiffer Partners evolved from our prior practice as Hardy Holzman Pfeiffer Associates (HHPA), a long-running and successful partnership that first became a force in American architecture in the late 1960’s. The firm produced an award-winning body of work that truly reflects American architecture.

In 1986, HHPA Founder Norman Pfeiffer established a Los Angeles office of HHPA, along with Associate Partner Stephen Johnson, that has been responsible for work with remarkable diversity and civic presence. Beginning with the Robert O. Anderson Building at the Los Angeles County Museum of Art, several projects at Stanford University and the renovation and expansion of the Los Angeles Central Library, the office achieved prestigious national and international commissions such as the DeBartolo Center for the Performing Arts at the University of Notre Dame, the Information Services Building at the University of Otago in New Zealand; Space Odyssey at the Denver Museum of Nature and Science, the new Library at the American University in Cairo, and the renovation and expansion of the landmark Griffith Observatory in Los Angeles.

In 2004, Norman Pfeiffer, seven HHPA Principals, and five HHPA Associates became the leadership of Pfeiffer Partners, an exciting new practice built upon the HHPA foundation and committed to continued exploration of history and context, the creation of invigorating places that celebrate public activity, and a collaborative design process. As nationally recognized experts in cultural and campus planning, restoration and reuse, libraries and theaters, Pfeiffer Partners is poised to be a continued force in architecture in the 21st century.
