"Dave Cole is one of those professionals who reminds you how productive collaboration can be when the players bring top-tier skill, competence and the ability to execute. What I value most about working with Dave goes past all that. In a way that few people are able, he checks his ego at the door, he listens, he pays attention to others’ insights and goals.  He’s perfectly comfortable with a clean-slate, and he will only apply his considerable expertise after he’s heard and understood everyone else at the table. If you were in a lifeboat at sea with this guy, he’d figure out how to make it faster and safer, where to point it, and give you a pretty good guess when you’d get to shore. Best of all, the trip would somehow be fun."

"I have had the pleasure of knowing Dave for over 10 years as a colleague, friend,

supervisor, and now as a client. At Barosense we collaborated closely to design and develop a reusable articulating stapler handle for use in bariatric procedures.

Dave has extensive knowledge of physics, mechanics, materials and design. With a passion for the highest quality, customer satisfaction, and on-time delivery, Mechanical Advantage LLC in Vermont is a reliable and cost effective source for my prototyping needs.

Currently, Dave and Mechanical Advantage have delivered numerous machined components, jigs and fixtures in a timely manner. Mechanical Advantage LLC is a company I can count on."
