Kelly was very timely and responsive in both scheduling an appointment and following up with a report. His on-site assessment was thorough and specific, knowledgable recommendations were made to address the issue. This was an outstanding experience.

We engaged with TDA to review our property. We had noticed some slightly sloped floors on the top level and wanted to understand the causes and remediation options. They were timely, thorough, and amazingly, performed the assessment for free. When we move forward with other projects down the line, we'll definitely reach out to TDA.

Kelly was very professional, knowledgeable, thorough, and overall great costumer service. Kelly takes the time to patiently explain the cause of your issue and different options you can use to correct the problem. I would recommend him to anyone I knew who needed a structural Engineer.

Called us immediately and came out to our project first thing in the morning. I told him that my wife was up worrying all night because there were lout popping noises in our roof and she wanted to move out to a hotel. He did a thorough inspection and explained what the noises were from and why they were common this time of year, especially in older homes. I tried to pay him but he refused, quite a gentleman, you do not find those kind of people around anymore. I would gladly hire these guys for ANY project I do in the future. Do not go anywhere else for a Structural Engineer....

TDA took on our small remodel project in November of 2009. Our plans were approved by the City with no changes or questions ( unheard of in our city). In mid construction, a short on a lumber order, could have delayed the construction for a week. TDA offered a structural change option with avalible lumber, resulting in no delays and the project was completed on time. Always accessible and great to work with, we will be using TDA on furture projects.

While Mr. Turbin is working on a proposal for the work, therefore he has not been officially hired, has been most engaging in providing an initial evaluation of the structural problem in my home. At this point in time, however, I thoroughly recommend him! Juan Monsanto

Kelly really worked hard to help us with the design of a vaulted ceiling. He knew what was needed from the city department, and understood the challenges we had with our old house. He was responsive, quick, and reasonably priced. His design and all his efforts resulted in quick approval from the city building department. I highly recommend TDA!

I communicated my urgent need for a Retaining Wall Repair Permit because my hillside was slowly moving towards my house. They came out Saturday Morning at 6am to assess my existing wall in my backyard. They completed the site survey on spot & had the finished design with calculations Monday Morning at my doorstep at 8am. We just pulled a Permit at the City and will break ground this afternoon. I did not think we would be able to get started until next week at the earliest. These guys exceeded my expectations. I will recommend them to anyone in need of a Structural Engineer.

These Guys are Great! They exude tremendous energy and drive to meet the needs of all involved. My Architect said he never has worked with an Engineer Like this before & he has been the business for 34 years... TDA delivered the proposal for my requested work & met me on-site the same day. We spent 3 hours brainstorming with my Architect and they finished the Schematic Design the same day. They are the most thorough, friendly, and competent Structural Engineers I have ever worked with. I highly Recommend these guys even if you are currently contracted with Another Engineer. GREAT EXPERIENCE!
