The success of renovation work relies heavily on collaborative and creative structural engineering in order to realize interior and exterior architecture goals. Tolga instinctively understood my design goals and in a very professional manner he crafted solutions to bring them to reality. Many thanks Tolga. I look forward to our next collaboration."

David came up with comprehensive blueprints for the entire remodeling project, and he also generated a great 3D renderings of the addition for us. He also got for us all the permits from the city."

"I had used Conrad's company in the past and knew he had good, experienced employees and that the work would be done properly.  This job from the beginning was going to be sizable and was to involve just the back yard and side yard areas with the patio flagstone work to be the biggest part of the job.  When I saw how good Gonzalo, one of the excellent masons Conrad used, I decided to enlarge the flagstone work to include the backyard sidewalk area done in the same style as the patio.  Conrad was able to give me a good price and we added that job to the project.  As the work progressed, I was able to see the quality of the work being done and I decided to included the front yard in the overall renovation and I did not regret my decision.  And once again Conrad gave me good, competitive pricing and it made my decision the expand the job easier.  I had many opportunities to see his employees at work and Phillip, working the irrigation and various plumbing jobs, was excellent and fantastic work was done by the brothers Gilbert and Able who worked long and hard, in the heat and on Saturdays to ensure I was pleased with the outcome of all the projects I had going at one time.  I changed plants and trees and locations, added flagstone for steps, adjusted irrigation lines and generally made several major changes to my original idea and never once did Conrad balk at giving me what I wanted. Conrad and his employees were always pleasant to be around, always answered my questions and showed me what they were doing or intended to do, all the time.  If I requested a special activiity or option I could be certain it would be done.  The finished landscaping is terrific and I'm very happy I had it done and happier even that Conrad was given the job.  I especially remember one email we exchanged near job's end when I made reference to a tree which to be changed out.  I don't know what I expected, but Conrad told me he would work to make me happy "until the end".  He did all of that and more.  Thank you , Conrad and Gilbert and Able and Phillip and Gonzalo and all the rest of the crew  who worked so hard giving me the yard I have wanted for decades.
