Vice President of Sales

Learn More

Chad Hawkins is a successful professional with an extensive background in technical sales operations and management. As the VP of Sales, he leads a team of talented sales experts by developing and implementing sales strategy, plus forging lasting relationships with key accounts and partners.

Chad obtained a BS in Industrial Engineering at Clemson University (go Tigers!).  His career progressed through the ranks of technical sales and sales management, working for a variety of organization types, including market leaders.  Chad participated in several sales and sales management training courses, including the Advanced Leadership Program at the Center for Creative Leadership in Greensboro, NC which helps leaders unlock their potential, clarify challenges, and strengthen their ability to achieve results.

A person who inspires Chad is Jeff Bezos. Chad said that there isn’t anyone else who has more successfully demonstrated success by prioritizing the customer experience. As Bezos said, “We see our customers as invited guests to a party, and we are the hosts.”

A recent project that Chad appreciates was a larger skid system that seemed risky on the surface as it was quite different than anything the team attempted in the past. Through collaboration and insight from many staff members, Hydro-Thermal was able to successfully build and deliver a product that solved customer pain points.

On a personal level, Chad enjoys pending time with family, golfing, reading and being outdoors. A fun fact about Chad is that he lived in Germany and speaks fluent German. Prost!
