Preferred Traffic Control is a family-owned business founded by Cole Hamlin, Chuck Hamlin, and Josh Greene. Drawing on years of telecommunications experience, we identified a requirement for superior traffic control services in the region and decided to establish our own company, beginning with a single truck and two employees.
