"Very experienced structural engineer who could analyze our rooftop deck and give us a plan for doing the roof and hotub of our dreams!"

"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"I hired Beginnings Engineering for a structural project on my 45-year-old home and worked with Jonathon Sipe and Nada. I spoke with several other firms in Orange County first. Most of the alternative proposals leaned toward complicated, expensive “perfect” solutions that might make sense on a new build, but didn’t feel grounded in the reality of an older home. Jonathon took a different approach: he listened to what I was trying to accomplish, worked through the constraints with me, and came back with a solution that made sense in the real world—while still being safe and code-compliant. On top of that, the experience was just… easy. Communication was straightforward, follow-through was solid, and they were genuinely friendly people to deal with. They weren’t the lowest engineering quote, but they were the lowest-cost path overall because their design avoided the unnecessary construction scope other firms recommended."

"I recently engaged Nick Engineering for a kitchen remodeling, and I must say, their structural engineering work was exceptional. Their design not only gave our house a stunning makeover but also made sure it is built to last. The teams professionalism, responsiveness, and commitment to meeting our expectations made the entire project a breeze. I highly recommend Sam and his team for anyone in need of outstanding structural engineering services for their home renovation projects"

"Raj is an exceptional engineer with a world view centered on value and helping people. He help me through a tough problem with a roof structure issue quickly and efficiently."

"Working with Jonathan has been a dream. This is the first time I've ever needed and architect and engineering for a home project, and wasn't sure what to expect, but Jonathan was great. He was incredibly patient with the adjustments and revisions that came with the process and pointed out some ideas that I never would have thought of on my own. As a bonus, the plans sailed through the city plan check, getting approved the very next day with no comments. I strongly recommend DesignX."

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"Very knowledgeable. Iâ ve dealt with a lot of Structural Engineers. His ability to relate complex situations into easy to understand explanations clearly shows how knowledgeable he is. His background in construction adds a constructability component that is unmatched. Highly recommended. ."
