Why Sentinel?

A Track Record of Success


Two Decades: Sentinel’s 20-Year Track Record of Success

Why has Sentinel continued to thrive where other fleets have failed? The credit goes to our employees. Our people are our number-one asset and the reason we’re widely regarded as one of the top fleets in the tank truck industry today.

We were founded in 1996 as a private tank fleet to provide transportation services for our parent companies at the time, Conoco and DuPont. Today, as a wholly owned subsidiary of Phillips 66, we’re known as the go-to company for handling the hardest-to-haul tanker loads. We are a leader in providing the safest, highest quality transportation services for crude oil, fuel, petroleum coke, lube oil and more.

Our professional drivers deliver quality service throughout North America logging over 30 million miles annually. Our strength and dedication to superior customer service begins at our headquarters in Wilmington, Delaware and continues throughout our nationwide network of over 30 terminals.
