    I had them perform a few projects, and all of them were completed on time! Very professional and cost efficient.

    I found Sam through Yelp. At first, we were both not sure whether we will work together because he…read morelives more than 20 miles away from where I live, and I'm the type of person who is always skeptical about what I read on the internet. But now I'm very happy that Sam decided to take on the job and develop the structural calculations and drawings for removing a load bearing and shear wall at my Condo. The Project started in September 2025 with initial submittal of permit application package to the City. It went into construction about four (4) weeks ago and was successfully completed today (5/8). During the process, we developed trust for each other. I contacted Sam numerous times for questions, problems and consultations and he was always responsive. He and my architect friend worked together to develop the initial design but had to modify it to overcome a major obstacle that came up during the construction. He came over for construction observations and gave instructions to the contractor how to strap the beams together for maintaining structural integrity of loading and shearing. His fees were much lower than another builder whom I also got a bid from, and his approach to things was much simpler and yet conservative to that from the other firm. I told Sam, whether it is good or bad, I don't usually do reviews for others. But for him, I will do one. I'm thankful to have a great team of Sam (the engineer), my architect friend, and excellent construction crew to help me complete this project.

    I am a homeowner and have only good things to say about working with Sam. He was recommended by…read moreour architect to do the structural drawings and observations for our renovation project. Sam is easy to work with, responsive and explains things very well - even to someone like me who doesn't have an engineering or construction background. He gave me a time frame that he needed to complete the drawings and stuck to it, which I really appreciate. He communicated well with my contractor and considered different options for how to approach the structural challenges. I've worked with other structural engineers over the years, and I found Sam to be the most professional. I've had engineers disappear mid-project, deliver weeks/months after they said they would, and/or bill more than initially agreed upon - not Sam. He does what he says. Definitely would use him again.

    I can't recommend Ben enough for any architectural needs, especially if you're navigating the…read morecomplex permit process in Malibu. From the very beginning, Ben has been incredibly professional, attentive, and proactive. What truly sets him apart, however, is his genuine heart and empathy for his clients. My mother's business had to be put on hold during this process, which was an unexpected and stressful time for our family. Ben didn't just treat us like another project; he truly understood our situation. He worked tirelessly to resubmit plans and handle corrections as fast as possible because he genuinely wanted my mom to be able to get back to work and reopen her shop. It's rare to find someone who takes your personal success so personally. Beyond his expertise, Ben's pricing is very reasonable and fair, he is not overpriced at all, which is hard to find in this area. He was also incredibly helpful and understanding by allowing us to pay in installments while the business was closed. This financial flexibility was a lifesaver for us and showed his true character as someone who wants to help, not just make a profit. If you want an architect who is highly skilled, honest, and truly cares about your family and business, Ben is the one to call. We are so grateful for everything he's done. Thank you Ben!

Due to circumstances outside of our control, our original plan checker was replaced, which caused delays and additional review. Ben stepped in and handled everything professionally, working directly with the city to resolve the issues and keep our project moving forward. His knowledge of the process and persistence made a huge difference. On top of that, his pricing is very competitive, especially considering the level of service and support he provides. Overall, a 5-star experience--I would absolutely work with him again.

    Ok first off let me say that Joseph is not only competent and highly professional but a great guy…read more I met him when I had a potential building code violation on one of my restaurants. It was absolute nonsense from the get go. However, the city had told me to close down until I could resolve the "structural problem with the roofing system". A neighbor who didn't like my business being there reported me and had influence over someone. I was in a word desperate. Joseph dropped what he was doing, came out looked at the issue (which he agreed with me was ridiculous). Ran calculations that evening. Drew up the calculations and a quick brief study which I took to the building department the next day. After about 40 minutes with the supervisor they realized the error on the part of the inspector and we re opened the next day. Now over 10 years later I think, there are no issues and all is well. Just the same way there were no issues for the last 40 years or so the building had been in existence. Joseph saved me...! Most engineers are highly reticent to step into someone else's problem, let alone sign off on a condition that existed before they were on the project at all. I honestly don't know how I found Joseph but it was blind luck. He is honest, reliable and best of all affordable. He only charged me about $1,000 dollars for what I described above. I was a stranger to him and he literally saved me thousands of dollars and several employees their livelihoods. The least I can do is to take my time and share what a wonderful thing this was to do.

    As a licensed Architect, I have worked with Joseph Mina and JN Engineering for the past 7 years…read more We collaborated on several difficult structures on complicated sites. Joseph has always been a wonderful consultant, attentive, creative and truly dedicated to finding the best solutions. In addition to being a great Structural Engineer, Joseph is also a true gentleman and an outstanding human being.
