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?
