Daniel has been so amazing and up front with his structural engineering advice. I came looking for a second opinion on whether or not a kitchen pantry wall could be safely removed. I haven't begun construction yet so i wasn't able to provide drywall-less photos and was looking for a quick online opinion. Daniel graciously offered his professional expertise through photos and videos i provided versus immediately trying to schedule me for an in-person consultation. He even stated he'd prefer to see videos/photos before scheduling an in person consultation to see if it was even necessary. I will definitely be seeking his services when time comes for construction. 10/10 initial impression and will definitely hire for services as needed. read more

Working with Daniel was a great experience. He helped me create custom structural engineered plans for an ADU I am working on in East Los Angeles. After searching around for several quotes, I found Daniel's pricing to be very reasonable. He was responsive, professional, and his sketch work was thorough and detailed. He was always there to answer any questions I had. Crucially, he also helped me navigate the painstaking plan check process with Public Works. Daniel made a difficult process much more pleasant, stepping in to provide policy guidance to the city to ensure my non-negotiables were approved. I couldn't have gotten through this without his expertise. I highly recommend him to family and friends, and I would definitely work with him again for any future plans. read more

We wanted this to work. Daniel was recommended by a building professional we know and trust. Referrals were all good. Initial interview went well. So we signed a contract in April for him to design a new house for us. According to the contract, at the end of two months we would have plans ready to submit for plan check. Somewhere around the end of July he evidently lost interest in the job. Responses to emails and phone calls was very slow, and there was evidently no progress on our plans. So here it is, mid-December. He has our money, isn't responding to messages, and we don't even have a floor plan. Extremely disappointed doesn't begin to describe it. read more

There were questions along the way because my client and I am not familiar with the process. Daniel was always quick to respond and explained things in a way we could understand. Due to the pandemic, the building department is not accessible resulting in longer approval times.

We recently needed to get a permit for some work done to our garage by the previous homeowners and the city needed a letter from an licensed engineer stating that the window put in the garage was structurally sound. I contacted a few places I found on Yelp but Daniel was the most responsive to my questions. He explained everything in a clear and detailed manner. After consulting with him through emails, I decided to schedule an inspection because he provided the most reasonable price and seemed very knowledgeable. A few other places responded saying they may need to remove some of the drywall by the window to inspect it but Daniel was able to prove that it was structurally sound using other methods without tearing down a part of the wall. We are very pleased with his service as he is very professional and was punctual during the visit. He provided a letter with 12 pages of very detailed plans that the city was satisfied with. He was just so helpful during the entire process. He definitely exceeded my expectations and I HIGHLY recommend him to others. read more
