Founded in 1946, what is now known as the Armstrong Group began life as Armstrong County Line Construction, contracting work ... for power and telephone utilities in Western Pennsylvania. In the 1950s we began to own and operate independent local exchange telephone companies. We expanded into the cable television industry in 1963. The 1980s saw us move into the security, restaurant and real estate development industries. And we’ve continued to expand and diversify. Our most recent addition has been Armstrong Comfort Solutions, a full service residential and commercial heating, cooling and plumbing provider. Seven decades old, the Armstrong Group remains a family owned and operated business, now employing over 2,300 people across the nation. Strong management, fiscal responsibility, careful planning and diligent research are hallmarks of the businesses that make up the Armstrong Group of Companies, ensuring the mission statement of our founder; Growth and Perpetuity. read more
