Mack Energy was founded by Frederick J. McCorry – “Mr. Mack” in 1931. He followed in the footsteps of his father, an oil man from western Pennsylvania, and purchased a small company in rural Berwyn.

Serving the Main Line & Chester County

The Rhoads Energy Family of Companies
share several values and key characteristics:

True to Our Roots. We work where we live, so we’ve gotten to know our customers – often through several generations. It’s no secret that people in our region value personal relationships. Our customers appreciate that they can have a real conversation with anyone on our team – even our CEO. That personal touch sets us apart.

Focus on Service. Our core business involves energy. But we recognize our real impact centers on the comfort of our customers. To succeed, we emphasize strong service and the development of programs that actually make it easier to do business with us.

Value Our Team. We learned decades ago that our employees are the key to continuity and longevity, so we hire and keep good people. Our team has responded with loyalty; average staff tenure is longer than 10 years, and we’ve been honored as one of the Best Places to Work in PA.

Involved in the Community. For decades, we've placed a premium on giving back. We support a range of charitable initiatives, from United Way to local youth sports. We’re even prouder to support our own team members who volunteer their own time and talents for community-building efforts.

Our shared philosophy has helped us build valuable relationships with our customers and our communities — relationships that have fueled the success of the Rhoads Energy Family of Companies.
