Joseph Phan & Associates is not a company. He works out of his home on 15182 Summerwood St. Westminster, Ca. 92683. He works on his own time and not yours. Very incompetent of his work and knows nothing about city codes. His associates(Yaghi Shucri Consulting Engi Irvine, CA) is even worst when it comes to measurements. They waste 10 months of my time and 12,000 dollars and there works is not accepted by the county. Now I have to hire another company to finish there Kindergarden works. My best advice is don’t hire these people even if they were doing it for free.
