Learn More About Our Business

The Centurion Tree story began in 1978...

… when John Miley built his first home in Perry Hall and installed a wood-burning furnace. Removing dead trees on weekends with a friend for firewood quickly grew into a business. It wasn’t long before John retired from Bethlehem Steel and Centurion Tree Experts became his full-time job.

John’s wife, Dianne, started managing the office and through the years has given our customers confidence in our services and always finds pleasure in assisting them.
John’s son, Tim, has been active in the company since he was 10 years old. Starting as the “gopher,” Tim has excelled in all positions, from dealing directly with customers to operating our 28-ton crane.

Meet Tim

John’s son Tim joined the team at just ten years old, acting as the “gopher”. Tim has since developed into a second-to-none climber and equipment operator. His speed, excellent judgement, and precision ensures that projects are completed quickly yet safely. Our customers often compliment Tim’s ability to manage difficult, dangerous trees – “He makes it look easy!”
