What Our Clients Say

Some of the recommendation reviews by our satisfied clients with our wonderful services

Essam was the structural engineer for the remodeling of our home; he designed the plans and supervised the work until completion. As first time homebuyers, we felt that Essam was able to empathize with us by understanding our needs and executing the plans. While other engineers told us that things could not be done, Essam was able to find solutions that were designed well and ensured safety. A trustworthy and reliable professional, Essam truly cares for his clients.
Sanaz Y. - 2013
Sam was an integral part, not only in the execution of our beautiful sunroom addition, but also in helping us develop a concept that greatly exceeded our original vision, with a dramatic roof line that allowed for more windows to make our sunroom addition light and bright. Sam is very competent and also a really nice guy.
Brian F. - 2015
Sammy is an entrusted engineer that is well skilled and extremely competent. With his expertise and knowledge, he led the project executing from start to finish in a reliable and timely manner. His professional referrals were also welcomed and just as honorable. We are grateful and very pleased with the completed work.
