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 ")."

"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."
