I feel incredibly fortunate to have been recommended this engineering firm. I am more than satisfied with my collaboration with Mr. Allo. The project involved an older building with very complex structural issues, including the removal of load-bearing walls – anything but trivial. Another structural engineer had proposed a significantly more expensive and impractical solution, despite a prior site visit. Mr. Allo, on the other hand, developed a well-thought-out, economical, and technically sound solution. The same was true when reinforcing the roof truss during the roof renovation: Mr. Allo calculates with extreme precision, anticipates needs, and always plans the best possible solution. In addition, he is very friendly, personable, and reliable. Absolutely top-notch both professionally and personally – I wholeheartedly recommend him.

Fast, competent, and fair support. We had a burst pipe in our basement. To replace the damaged pipe, a section of the pipe had to be exposed. To mitigate potential structural risks, we urgently needed a structural engineer's report. I contacted Mr. Allo on a Friday evening – despite the late hour, he answered the phone, which is anything but a given. Due to the urgency, an appointment was arranged quickly. It's particularly commendable that the initial site visit was accommodating and non-binding, allowing Mr. Allo to first gain a professional understanding of the situation. Only after this was the report commissioned and prepared. The entire collaboration was very professional, transparent, and seamless. The report was clear, well-founded, and gave us the necessary confidence for the subsequent work. The pricing was also very fair. I have rarely experienced such a level of service. Thank you very much for the prompt assistance and the pleasant collaboration!

Mr. Allo prepared an expert report for us regarding the planned chases for the partial rewiring of our house. He advised us very transparently, thoughtfully, and competently. The report was also completed very quickly, which was a huge help. We also received prompt answers to our questions. We can absolutely recommend him and are very grateful for his professional and friendly service! :)

I just wanted to give a quick shout-out to Razan Allo (Allo Engineers). He did the structural calculations for a lintel when I was creating a wall opening, and I'm really happy with the results. The whole process was incredibly quick and straightforward. You can tell he knows what he's doing. If you're looking for a competent structural engineer who's easy to work with, he's the one for you. I highly recommend him!

Working with Rezan Allo was perfect at every stage. His ideas for incorporating even complex structural components were implemented brilliantly and made my project truly special. He was always available and provided invaluable advice beyond the scope of his work. I'm already looking forward to many more projects together.
