I'm glad you liked the concept. Here, I am taking it a step further. This logo comments on the process of therapy, represented by the orange line as well as the "shift" that occurs in successful therapy represented by the chaotic half-sphere and the calm half-sphere.
Great, thanks. I think I'll let this stand. It looks like you extended the contest. I'll revisit the design in a few days to see if I can improve. In the meantime, if you can think of anything you'd like to see in the design, let me know. I took a look at your website and think this logo can be incorporated easily.
