"The owner is a very knowledgeable, professional engineer. He communicates articulately and enthusiastically. He has a lot of experience with varied engineering projects. I recommend him highly."

"Tom at TAS Engineering was professional, friendly, helpful, patient and highly competent and efficient. He did the assessment of my attic structural issue and identified the simplest and most cost-effective solution. He ensured that my contractor did the work to his specifications and provided the certified engineering letter that all had been addressed properly. This was exactly what I needed. I would highly recommend him and would hire him again."

"Zach was very knowledgeable, friendly, and finely a Structural Engineer who pointed out the obvious with our structural problems."

"the project itself was great. Got that taken care of. 2026 i had 2 more projects reached out but i never got a response."

"Structural engineer came by to confirm if wall was non-load bearing as suspected. Confirmed, can now move on with my project."

"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."

"Tony was thorough, friendly, and knowledgeable. He helped us understand why our ceiling was cracking and discussed how to prevent further uneven settling. Highly recommend!"

"Jeremy was extremely professional and efficient and was so amazing to work with!!! He literally called me the very night that I submitted a request for an engineer. Very impressive and would absolutely hire him again or refer him to anyone who needs a structural engineer."

"Chuck did a fantastic job, his plans were very detailed and exactly what we talked about. Through the whole process Chuck has only been a text or a call away and has come to the site through out all the construction to check on the progress. Chuck is very easy to work with and we would for sure recommend him."

"Bryan came out and was very thorough with the inspection. He was very informative and explained things well, I will definitely be using him and his business if the need ever arises. I would highly recommend him!"
