Ryan Joyce Structural Design is a growing San Francisco firm whose partners have over 50 years of combined experience providing consulting structural engineering services in the San Francisco Bay Area.

Founded in 2017, RJSD specializes in structural design of new buildings and seismic retrofits of existing ones. We focus on doing great structural design work, producing clear and thorough documents, and providing exceptional service to our clients.

Located in downtown San Francisco, RJSD believes in being active in both the Bay Area and in the structural engineering community. Much of our work is for public agencies, and it is deeply satisfying to help improve our community around us. We also believe passionately in mentoring our staff and the structural community outside of our office, through day-to-day interactions, more formal educational opportunities, and SEAONC mentoring programs.
