Matt arrived on time and was courteous. He listened to me when I said to start camera-ing the sewer pipe at the toilet where another plumber pulled tree/shrub roots from my toilet. Matt removed the toilet and camera-ed the pipe starting at the toilet. It turns out the roots entered the toilet from a gap between the slab and toilet flange, which was visible in the camera monitor, and Matt pulled out a root that had ringed itself around the lip of the flange. He then replaced/reinstalled the toilet, complete with a new wax ring and caulking around the base of the toilet. Matt also cleaned everything up when he was done. My task is to completely remove the offending tree and shrubs. I'm very grateful that It wasn't necessary to jack-hammer my post-tension foundation slab, and that my sewer pipes are intact. Additionally, Option One comes to Casa Grande, AZ. Thank you, Matt and Option One Plumbing.
