I am very disappointed with the level of service provided. The week prior, we had a detailed…read moreconversation regarding a resolution for an existing structure on our 5-acre property, and the engineer agreed to schedule an in-person consultation. We confirmed an appointment from 12:00 PM to 1:00 PM in the Temescal area of Corona. Despite his office being located in Corona, he stated he was unable to find the property, even after I provided clear directions. My elderly parents were present at the property to assist, and I had arranged to meet him during my lunch break from work. Upon arrival, I found no issues accessing the property there were no "large rocks" blocking the entrance as he claimed. Unfortunately, he had already left before the scheduled time without proper communication. Instead, he states that we send photos of the structure. This experience was a significant waste of time and demonstrated a lack of professionalism, reliability, and respect for our schedule. I would not recommend this service based on our experience.

When he came out to take measurements, he offered smart suggestions that made our project more cost-effective while also adding long-term value to our home. Ramy delivered the plans ahead of schedule and took the time to walk us through everything in person. The city of Claremont's permit requirements are very strict, and it was clear that Ramy knew what the city would require. When the city had requests we didn't agree with, he communicated directly with the city planner on our behalf and guided us through the process with confidence and clarity. You get what you pay for with Ramy--his work is high quality, detailed, and thoughtful. His expertise, responsiveness, and professionalism made a stressful process feel smooth and manageable. We highly recommend him for any home or ADU project. He is absolutely worth it.

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.
