Dennis K. Burke is available on call 24/7/365 to meet your fuel demands. We run a full schedule of drivers seven days a week, plus additional drivers are always on call for emergency coverage. A non-business-hours answering service pages the on call dispatcher, who responds by sending a driver to your location as swiftly as possible. This is just another service we offer to give you the peace of mind that comes from knowing your fuel will be there, on time, on budget, every time.
