Worst customer experience possible. Incompetence surpassed by arrogance. Took over 2.5 years to have plans that could be built on a 100 sq ft addition. Multiple reviews due to incorrect assumptions or lack of detail. Catastrophic flaw designed into the first attempted "plans". Was forced to bring in a 3rd party engineer to resolve flagrant issues with the design. Complete lack of understanding of residential roof design. Causing massive delay and over design. Would not recommend them to build an outhouse.

After a nightmarish experience with a crooked contractor, I was left on my own to obtain plans and a permit for my unfinished deck. I reached out to ISTA - their structural engineer Pedram has been nothing short of amazing. He came to my property to verify measurements to make sure the drawings would meet code, spent a great deal of time observing all structures and pointing out in great detail everything that needed to be fixed for safety reasons (things that were missed by my city inspector), offered alternatives to costly fixes, then worked very quickly to draw plans as he empathized with my situation. He even called the city's building department and got everything resolved on the spot. Five minutes after his call, my permit was approved!! And through all this, Pedram was so friendly and empathetic. Everyone in that office I spoke to has been very nice as well. I will definitely use ISTA again for all my future projects.

I needed an ongoing project assessed immediately. Pedram was great, he was able to meet with me within a day. He took his time to make sure he had all the information needed to write an Inspection of the addition plan and the construction. Very thorough and professional. I would highly recommend this company.

Pedram arrived at the time that he promised and was thorough with his assessment. Addressing the issues but also looking at all the evidence or information available to make a decision. I recommend him as a solid engineer, capable in this field of work.

Pedram was great. He did a thorough job for a fair price, and quickly. He even rescheduled other plans to make a more cenvenient appointment for me. I would definitely recommend him and will likely be going with him for future projects.

Pedram provided us with great service at an exceptional value. He completed the necessary drawings for our structural wall removal, and we were able to get a permit with no comments from the city. I would recommend to anyone looking for a structural engineer.

I called ISTA Engineers on a Sunday to set up a last minute foundation inspection before we invested in some concrete work scheduled for the following Tuesday. Pedram made time in his schedule and came to my home the next day. He was courteous, professional, and thorough in his analysis. He gave me several recommendations and his follow up report was detailed and helpful. I highly recommend ISTA Engineers!

They got back to us very quickly and Pedram, the Ista Structural Engineer, came to our house that evening. Extremely professional and knowledgeable. A week later, we have plans to pass along to a contractor for removal of a load bearing wall. I recommend them highly and will use them again.
