Charlie the Dog - Dog

Charlie the Dog moved up here from Virginia in April 2009. His big sister Sandy taught him how to bark and walk up and down stairs. He went immediately to work in order to help pay for all the food he consumes. Charlie spent years as an active member of PAWS for People. He enjoyed visiting as a therapy dog and providing smiles. He enjoys relaxing, protecting his home from squirrels, and spending time on the road visiting Hillside customers.

Jim Sellers - Owner/President

My grandfather and grandmother Bill & Maxine Sellers started Hillside in 1952 to service the fuel needs of farmers in Fair Hill, Maryland and Southern Chester County, Pennsylvania. My mother and father Jim & Barbara took over Hillside in 1970. They moved the company to Newark immediately after, and by 1978 Hillside was in our location on Brookhill Drive where we still are today. I was born in 1974 and have known not much more than the workings of Hillside. I was raised in our family business and am happy and proud to continue my family’s name, and provide the best possible customer service and relationships possible.

In my free time I like to make fun of the people I am lucky enough to work with, the outdoors, hiking, camping, biking, and spend time with my wife and dogs. I also like to race toy cars, something I can’t seem to outgrow.

Jerry - Service Manager

Jerry started out with Hillside as a helper eighteen years ago. Along the way he took several courses and earned his Journeyman certification. Jerry is the true American Dream and the full package. He started at Hillside coming from a job as a line cook. He was an extra set of hands. Now after hard work and experience he is one of the most knowledgeable and creative people in our industry.

When he is not working he enjoys snowboarding, hiking, camping, biking and listening to music. He has been spending some time working on his 1986 VW Vanagon in hopes of traveling with it.
