Golden State Seismic And Structural Inc. Construction
My name is Brian Bouchard, I have been in this business for the past 19 years. I was with my previous employer for 18 of those years 10 of those working as the project manager before I decided it was time for me to go out on my own. I am very dedicated, hardworking, and knowledgeable, and treat every project with the same care and attention I would as if it were my own home. I am always available for my clients when they have questions and explain every step of the project with extreme detail so we are always on the same page. Most of my work is located in the Bay Area, but I travel all over. I look forward to working with you in the future.
