David S. Earles, PLS

Chief of Surveys

As Chief of Surveys, Dave is responsible for all aspects of the firm’s survey practices. And, with over 40 years of experience, Dave has certainly seen the profession evolve.

“I was drawn into the profession by an interest in the history of surveying,” Dave says. “CMT has given me the opportunity to grow and introduce newer, more-advanced technology every step of the way to enhance our services.”

Dave and his crews deploy their surveying and data-collection expertise on all of the various expertise areas and markets we serve.

“I’m grateful that the work we do enhances communities and helps to make it a better place for everyone to live,” Dave says.

For recreation, Dave enjoys snow skiing and visiting different wineries. And, even though it’s part of his job, he also really likes flying the drones.
