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

"We are planning on removing some walls in our house. I contacted Crosstown Engineering to see if they could help. Their engineer, Angel, came out to take a look. Angel was very professional, right on time, and did an awesome job explaining everything to me. He pointed out the changes we would need to make, helped me to understand the process to tear down our walls, and provided an excellent written report for us. If I need structural work or any other type of engineering, I am coming back to Crosstown Engineering."

"Dave was absolutely great to work with. This is the first time for us to build a house. We met with Dave at our lot, which has quite a challenging slope, and immediately liked him. We gave him an idea of what kind of house we wanted and he ran with it. He has great ideas and imagination when starting from scratch. He was very patient with us as we made changes to the original plans. Even more important, he was straightforward when an idea of ours just couldn’t work and he explained why in layman’s terms. Likewise, he was forthright when comparing different ideas with cost in mind. When it was all said and done, we got fantastic plans for the exact house we wanted and we are very excited to see it completed. His price was very reasonable and more cost effective than a couple other designers we checked with. We HIGHLY recommend Dave O’Brien to anyone wanting to design/build a custom home."

"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."

"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."

"Nick and Doug, two really great guys. Nick provided honest feedback and gave a really strong bid, I was impressed with his sales acumen and direct communication. Doug was punctual, communicative, and motivating for his crew, and really seemed to go out of his way to make sure the job was done right. Doug's crew worked their butts off and did an outstanding job, it was probably the most frustrating job the crew has done, a very hard excavating pier and beam job. I really appreciate them, especially in knowing the fact that my home and it's foundation is properly repaired and safe for my family."

"They had to do the soil test before they could decide how to design the structure. The thing that stands out is the knowledge that they have of structural engineering and honesty. By honesty I mean they don't lie by admission or position, in other words they are very straightforward and knowledgeable."
