my experience with this company was absolutely horrible!…read morefirst of all to survey a property isn't the cheapest investment so you'd expect the service to be half way descent. This company took several hours to respond back to me to schedule appointment, that alone should have been a red flag but I still gave them another opportunity. Appointment time frame was 7:00am-7:30am, when he hadn't arrived by 8:30am I called them to see if he was late, they gave me BS that he was at the county getting info on my property. Then stated he'd arrive by 12:30-1:30pm again DID NOT SHOW! (keep in mind they already had my $1,500.00 deposit) Basically this went on all day didn't show up until 4:30 pm and the man that showed up had no idea what he was there for instead wanted to chat about his kids instead of getting the job done! I contacted there office and told them to just have him leave my property. waiting 9 hours is ridiculous. save your money and time stay away from this company!! unprofessional and unreliable, how people run there business like this is insane!

I had the pleasure of working with an exceptional engineer Hamid who drafted the plans to convert…read moreour kitchen into an open-concept layout, which required removing a previously load-bearing wall. From start to finish, the level of professionalism, expertise, and attention to detail was truly outstanding. The engineer demonstrated a deep understanding of structural integrity while also respecting the design vision for the space. He carefully evaluated the existing structure and developed precise plans to safely support the load while allowing us to achieve the open, modern kitchen we wanted. His calculations and documentation were thorough and well-organized, which made the permitting and construction process much smoother. What impressed me most was his ability to balance technical precision with practical solutions. He communicated clearly, answered all questions patiently, and ensured the plans were easy for the contractor to follow. The result was a seamless transformation--our kitchen now feels bright, spacious, and beautifully integrated with the rest of the home. If you need an engineer for structural modifications, especially for projects involving load-bearing walls, I highly recommend his services. His expertise, reliability, and commitment to quality truly set him apart.

I had a roofer tell me that my entire roof support structure was in danger of failing and they had…read moretheir structural engineer come out. The estimate was astronomical and would take months to complete. I brought in Distinguished Structural Engineers to give me a second opinion. They give me a written analysis with lots of pictures pointing out some issues, but they gave us peace of mind that the structure was fundamentally sound and only needed attention in a few areas. We used one of their recommended roofers and spent a tiny fraction of the first roofer's estimate to correct the issues. I highly recommend Distinguished Structural Engineers for any work you're considering.
