September 11, 2025

After years of dedicated leadership, Tony Carreira is stepping down as President. Tony joined K-Line in 1990, during its early years, and was a pioneer in the development of polymer insulators. Over the course of his career, Tony was instrumental in shaping the company’s direction and success.

“His vision, dedication, and leadership have been key to building K-Line Insulators into the trusted and innovative company we are today, and we are eternally grateful for his contributions,” said K-Line via LinkedIn.

“We are proud to welcome Dalton Kellett as our new President. Dalton represents the third generation of his family’s legacy in the utility sector. His grandfather, Glenn Kellett, founded K-Line Maintenance and Construction in 1967, followed by the establishment of K-Line Insulators in 1983.

Dalton brings a unique blend of engineering expertise and high-performance experience from his background in motorsports. His strategic mindset and collaborative approach have already made a strong impact at K-Line Insulators, and we are confident he will continue to guide us toward operational excellence and long-term growth.”
