Bill Jetton grew up in a small town on the gulf coast of Texas.  He earned his BA in economics from the University of Houston in 1973. He left for California shortly after graduation and began apprenticing as a carpenter in Mendocino. “As a young man, I was drawn to carpentry because I liked working with my hands and being part of a team.  Building my company has been exciting and fulfilling in both respects.  Once I started building I never wanted to stop.”
