"Pedro is a very professional Structural Engineer. Very knowledgeable."

"We started working with Mr. O'Brien a few weeks backs for our first custom home building project. Working with the Mr. O'Brien is an absolute pleasure for so many reasons: His experience is unparalleled, he has an abundance of patience, he is highly professional and quickly developed a shared vision for the project with us. He listened to our ideas and worked on them develop a coherent design for the house to the vision we had in mind. We went through a few versions but Mr. O'Brien worked very efficiently through the process and in turning the drafts around. We were given personal attention and value the input and experience that has helped shape our end product. Thank you for all that you have done for us. You were the Big Starting block ")."

"He was very professional and insightful about the foundation and the slight slope I did not notice until he pointed it out will use him again."

"Great people to work with from the owner to the designers."

"I am general contractor They did three different job for me. Their work was good. The price was reasonable and on time."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."
