Why not just ask him? Leave a message on his voice mail. Maybe he can't come out and tell you since he works for the place where you see him, but I'm sure if you brought it up he would have no problem telling you if it might be a possibility for you to see him at the place that operates on a sliding scale. Or go ahead and call there - even if you can't see him, it would be a way for you to continue getting therapy.
Good Luck!
