How Will I Get to Find Drug Rehabs in Lufkin, Texas?

I want to know how I’m going to go about finding drug rehabs here. We’ve only just moved here a year ago, and I haven’t seen any rehabs still. I need to help my son regarding his school project. It’s about drug rehabs and addiction treatments, and we just want to get detailed information as well as a few pictures if they’ll let us. Suggestions would be very much appreciated.
