My name is Ethen Waterman, and I’m the founder of Tristate Fleet Solutions — a company built from the ground up to serve a critical need in the heavy-duty repair industry: dependable, skilled, and honest diesel service that keeps commercial fleets operating without disruption.

With nearly a decade of experience turning wrenches in the diesel repair world, and a background in the broader service industry, I’ve seen the frustration that fleet managers face when service providers overpromise, underdeliver, and fail to show up when it matters most. That’s why I created Tristate Fleet Solutions — to set a new standard in fleet service across southern New Hampshire, Vermont, and Massachusetts.

We offer comprehensive on-site maintenance, light to moderate repairs, diagnostics, and customized fleet service contracts tailored to the unique needs of each client. Our focus is not just to fix what’s broken, but to prevent downtime before it happens — with proactive maintenance strategies, streamlined communication, and a commitment to craftsmanship that shows in every detail.

At Tristate, we believe integrity, professionalism, and technical expertise aren’t optional — they’re the foundation. When we say we’ll be there, we mean it. When we fix something, it stays fixed. And when we partner with a fleet, we treat that responsibility like our own business depends on it — because it does.
