"GS engineering, and Sim Singh in particular have been fantastic to work with. I am a general contractor and have had to hire a number of structural firms over time. Sim offers a very rare combination of a high level of skill in a highly technical field (specifically engineering) a high level of professionalism, and an overall pleasant personality/demeanor. As long as he has the time to take my calls, it is doubtful that I would ever call a different structural engineer than Sim."

"Before buying I needed a specialist to look deeper into a potential issue, Greg was very knowledgable, friends and as it turns out just the guy for the job. He exposed all the issues and made my choice of not buying a house an easy one. Great to work with, has pest and structural qualification and was very reasonable. I'd highly recommend him and will be calling him again soon when I find another house."
