Testimonials
In my opinion, TSD is “above the many” I have worked with in the last 30 years. They are super people and great engineers.
I have been working with TSD before TSD’s inception! I knew both Casey and Chris when they worked for someone else. I followed them to TSD. I really like their personal touch, their quick response, and flexibility.”
I really appreciate their personal involvement.
I have been working with them for a few years now. I think Walgreen’s recommended them to us. They do a good job.
I work with TSD because they are local and due to the quality of their work. I am very happy with them. In fact, I think that they are one of the top 5 civil engineering firms I have worked with in the last 20 years.
