Success Stories

“We wanted to make sure our profits were coming back to us, not staying in a private company or head office. After purchasing another yard and moving our buying over to Castle, we found that the rebates and profits that came back to our company actually tripled after the first year.”
Leigh Wilson

“Castle head office runs very efficiently. As an independent, we have all the information and support we need for us to be successful.”
