Our Commitment to Community

Callenor since day one has been invested in our employees and our community. What started as a small family business has turned into a multi facility, independently owned organization. Many of our employees not only become lifelong employees, they become family. Callenor and LCH also have a strong commitment to various charities and non-profit organizations.
