"Eran quickly responded to my inquiry regarding a load bearing structure of my home. He sent his structural engineer to determine if the structure was a load bearing problem. The engineer was able to determine 100% that it was not a load bearing structure. I would definitely recommend them to anyone who needs structural engineering solutions."

"-It was about 2 weeks ago that I met Mr Sal and he cam to see the project site as well to take the measurements required next day later he immediately scheduled an appointment with my local city of Westminster to find out what was exactly requested soon after he left it took only 3 days for him to develop all the structural calculations for the mother-in low quarter and the 2 car garage I was extremely pleased for his professionalism and fast expedited work. The quotes that I was provided from him were by far quite fair than the other I had interviewed prior of meeting him. Mr Sal truthfully went the extra mile to make it happen for what I was looking for. I therefore would Highly recommend to anyone in need of such works to look for Mr. Sal from AAA Engineering Design, you will never be disappointed. I want everyone to know that he is truly a great asset to our community. Thank you John Trimarco"

"I have known Steven for almost twenty-five years, we have worked together on various projects in the Film/Television industry. Steven is a good designer who is versed in many styles and has a full knowledge of period details. He has a sound understanding of architecture and knows how to create useful and attractive spaces; heâ s also a genius when it comes to problem-solving. Heâ s up to date on all available materials and how best to use them. Steven has a strong work ethic and is very conscientious, and his sense of humor and light disposition puts anyone at ease; he gets along well with people. Recently, I had Steven draw up a ramp and a flight of stairs for the front entrance to our condo building, and as expected, he did a splendid job. We worked on the design together, and he prepared the working drawings and documentation. Then, he saw it through the local authorities here in Redondo Beach. I highly recommend him to solve any design requirements you might have."
