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 ")."

"We have used Simonson Design as we went through an earlier design phase several years ago on our yet-to-be built new home, which we put on the back burner for several years. Presently, with a new design approach, we have "reset" the project back to the start and are excited to have the Simonson Design team once again by our side as our dream home design and plans come to fruition. We regularly recommend Simonson Design to others that are about to build but don't know where to start."
