Arrived on time, was very polite, and very detailed in going over his assessment of our home and even the proposals the other contractors sent us. For significantly less money than the work proposed, he was able to put us on the right track and avoid costly work that wouldn't have addressed our principal concerns. Will definitely be calling Jeff again if we need any future structural work.

After pointing out the areas of concern to him, Ken offered a couple non-serious possibilities for the phenomenon, and was able to assure me there was no threat to either the structural integrity of the house or the cement slab foundation - and pretty much bottom-lined it, saying there's really nothing to worry about. I really appreciated Ken's easy-going demeanor, and sensed zero interest in him trying to sell me a repair service that wasn't needed. Ken is just an honest guy offering his experienced opinion - in no doubt, putting yet another homeowners' unwarranted concerns to rest. Would be nice If all companies sent inspectors who operated the same way as Ken.

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.
