Our Story

For almost a century Hi-Ho has built a reputation as a local company synonymous with success. The foundation of this success has always been and remains a commitment to the communities we serve and an unwavering dedication to enhancing the customer experience.

Today the Hi-Ho D’Addario entrepreneurial spirit continues to thrive. Asphalt plants, fuel storage facilities, sand and gravel plants, cell transmission towers, and billboards throughout Fairfield County are just a few of the industries the Hi-Ho D’Addario empire touches. Add to this a portfolio of various real estate holdings throughout Connecticut and technology companies with offices throughout the U.S. Hi-Ho D’Addario truly has become a company with a national reach yet one that has always maintained a local focus.

Hi-Ho Energy Services is the quintessential example of that local focus. Built on a single mission of delivering a best in class customer experience is what drives us every day. Through a combination of fair pricing and industry leading service, we continue to build  our impressive market share of commercial and home heating oil customers in Fairfield County and lower New Haven County. We are extremely proud of our past, but we aren’t stuck in it. Rather we view almost a hundred years of experience as a foundation on which to build a brighter future. As a direct result of this experience, we have crafted an industry leading customer service-first culture.  This culture is firmly built on doing the right thing, the right way, every time.  Our sincere hope is that you will join our family, experience this first hand, and that we can establish a relationship with you as our valued customer that will last for years to come.
