I had a very difficult (So I Thought) problem I was dealing with at one of our locations. Tony showed up and within minutes he made me feel at ease as he explained to me the problem was not as monumental as I had thought. Moving forward, RES will be the ONLY place I go to for my Structural Engineering needs!

Tony is a knowledgeable professional and unlike others, he actually answers his phone calls. Very few do that these days. My experience tells me that all his 5 star reviews are real.

Tony was incredible, very responsive and answered our questions even after our appointment date. The information he gave us was extremely valuable at a time where my husband and I were very stressed. He was kind and thorough. I would highly recommend him. Our neighbor used his services and was very satisfied as well.

Tony was very responsive and helped me to determine the scope of my problem on very short notice. He recommended a flood mitigation plan which is yet to be installed (waiting on contractors) but I am confident will alleviate the issues at my property. Both knowledgeable and professional - canâ t recommend enough.

Tony was excellent with managing the project. I travel a lot for business and my wife was the one in charge. She has an has a moderate grasp of construction and he made everything very simple and understandable for her to feel comfortable with the design and construction process!!.
