Report
Public works GC with token offices in Costa Mesa and Redwood Shores.. In my opinion, SJA is essentially a small company with minimal office structure; they also struggle with quality recruitment in the LA/LB market (this is based on seeing multiple recurring ads on employment sites as well as fresh grads being on-boarded in PE/marketing roles). After putting in solo 10+ hr workdays I came to realize other firms have more efficient & quality operations, value relationships, and provide streamlined access to upper management
Pros: The Costa Mesa office is in a nice location right next to JWA; PW

S.J. Amoroso demonstrates the epitome of professionalism and high quality construction day in and day out consistently. They listen to both their subcontractors and clients and are extremely fair in even the most difficult of situations. I have been working with them as a subcontractor for over two years on a multi-million dollar hospital project, and have nothing but great things to say about their knowledgably, ability, quality, and customer service. If you are looking for a top tier contractor, I highly recommend giving these guys a call.

Our company has been doing consistent business with SJ Amoroso for more than 20 years. We've found their management, administrative and operational staff to prefer a partnership approach to doing business. SJ Amoroso seems to place value on fostering relationships with their subcontractors and treating them in a fair, equitable and consistent manner. I would not hesitate to recommend doing business with Amoroso to others.
