Easy 5 stars from me…read more Hired Artoo Design to help with plans for a renovation project in my home. Because of the structural and electrical scope, I decided to build fully permitted and up to code. I hired Artoo twice. About 18 months ago I bought a one-time consultation. The consult fee is not cheap, but it's totally worth it. I got a full preview of everything that would be required for my project - sizing of structural members, ratings for materials, and what would (and wouldn't) fly with city inspectors. I also got a handful of solutions for things I didn't know how to handle. The meeting really streamlined my planning and thinking about design tradeoffs. The second time I hired Artoo (December) was to do the full construction plans. I met with Ramy to do an updated plan review and for him to take some measurements. I really felt like he was taking my input and we were working together on the final details. Then the quality of the drawings themselves are impeccable. In a previous life I did heavy AutoCAD drafting, so I'm very picky about drawings being accurate and complete. They were also turned around really fast. Much faster than I could have drawn in my prime. Next was probably the best part - Ramy said he would help with any notes from the city plan review process. I was worried how that would go. We had to do some revisions, but it was totally painless thanks to hiring the right company. I felt unstoppable with Ramy as a partner, and I got everything I wanted approved by the city. I'm writing this review today (August) because I had another small question about the plans, and Ramy basically answered my email immediately. Super tight customer service. I don't always have the budget or time to build things right. Artoo Design is one of those companies you should hire when quality and time is important. When you have a project that needs the best, this is the group to go to.

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.

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.

These 5 star reviews have to be from friends and family. 1. I couldn't get the staff to answer emails in a timely manner. 2. The engineer made changes that I never agreed to. 3. The engineer could not understand simple concepts. He would ask me a question. I would answer it then here we are 6 weeks later going over the same questions. 4. The engineer made a request. I honored the request. I reference the request in an email and he tells me he never made the request. I attach his emails with the request! He then sticks to he didn't make the request. I have at least 15 total complaints but I will stop here. This was by far the worst engineer I have ever done business with. Its hard to believe businesses like this are still operational.
