Nabih Youssef founded the firm, Nabih Youssef Structural Engineers (NYA), an internationally recognized structural engineering firm with offices in Los Angeles, Irvine, and San Francisco, in 1989.

Mr. Youssef is a registered Civil and Structural Engineer and is a recognized expert in seismic design. He is one of the world’s leaders in the field of earthquake engineering, development of standards and innovative concepts.

Mr. Youssef has been a leader for the concept of Performance Based Design, base isolation, and the use of steel plate shear-walls in areas of high seismic risk. Nabih’s dedication to his work and collaboration with peers are leading aspects of his character.

Mr. Youssef chaired the Seismic Safety Committee for the Governor’s California Building Standards Commission and the City of Los Angeles’ Mayor's Blue Ribbon Seismic Hazard Reduction Committee, has written numerous technical papers, and taught classes at multiple Universities. Additionally, he currently serves on the University of California Seismic Advisory Board.
