Giuseppe and his team did the structural drawings for a new spec home my company is building in Oakland. His team is thorough, responsive, and accurate. What's more they produce only what you need and no more, saving you time and money. They were also able and very willing to create the design that met the structural requirements at the lowest cost. I highly recommend them.

Like many other reviewers, I met Giuseppe Sircana after I had to do a seismic upgrade for my six unit building in San Francisco.  After interviewing several architects, I selected Giuseppe because he was prompt, knowledgeable and honest.  He easily guided me through the complex and bureaucratic rules of the building department.  Having dealt with many professionals in my career, I can honestly say that Giuseppe is one of the best.  He gets my highest recommendation.
