Randy Godier
Head of Sales, Dotec Engineering
Randy Godier has been in the sales game for over 30 years—which either makes him incredibly experienced or just really good at avoiding retirement. As Head of Sales at Dotec Engineering, he leads with a mix of old-school know-how, customer-first instincts, and just enough charm to keep meetings interesting.
Randy’s superpowers include solving problems before they even fully exist, communicating like a seasoned diplomat (or at least like someone who’s had a lot of coffee), and making sure clients feel heard, valued, and not just sold to.
When he’s not closing deals or coaching his team, you’ll likely find Randy enjoying a long walk on the beach, a crisp glass of chardonnay in hand, pondering life’s big questions—like what was Diddy doing with all that baby oil?

Client Testimonials
“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.
