About us

John S. Apolis, P.E., President of C, offers over 30+ years of experience in Structural Engineering Design for almost every type of construction project. We have provided design many types of structures. Our design costs are often lower because as a smaller firm, we have lower overhead costs. In addition, our turn-around times often are faster, because of the way we organize our work schedule. We typically provide full structural design for additions and remodel projects for 100 or more satisfied architects and homeowners each year, as well as a similar number of smaller "one day" or even "two hour" projects. We try whenever possible to give you what you need, when you need it. No project is too large or too small. If you are looking for a structural design firm which will stand behind their work, and provide you with timely and cost-effective structural design for your remodel, look no further.

I appreciate John a lot. It was easy to coordinate schedules for the home visit. He sat down and talked to me about how to proceed on a project that was more complicated than I thought it was going to be. He also turned around the calculations that we needed super fast. Highly recommend!

Very responsive and John came out to see our project within 24 hours of our initial contact. We only needed him for less than half an hour, but still paid the full hourly rate which was a little higher than others. We were grateful for his extensive experience, however!

I hired a few structural engineers to evaluate my situation and CSES was by far my favorite. They were pragmatic, realistic and knowledgeable.
