      “True Professionals”

      DOTec did the final design and engineer stamped drawings for my shipping container house. Based on my interface with them they were responsive to my needs and did a good. I have recommended DOTec to others, and will use them again should the need arise.

      “Great Solar Design”

      They were fantastic to work with. A manufacturer recommended them for my Solar/Structural engineering project. They quoted a fair price, met my difficult schedule and provided a quality set of design documents for the project. I have recommended them often and will work with them again soon.

      “Job Well Done”

      We would be able to use their services on our out of state projects as needed. They would provide us with engineered sealed drawings and calculations quickly. Thank you for a professional job done well.

      “Top Notch Service”

      Been doing business with Dotec for a long time. While we are a regular/repeat company our jobs are small potatoes compared to most but that has never stopped us from receiving top notch service. I have recommended Dotec to many and will continue to when I have the chance.
