The guarantee that I do give is that if, after your first appointment you have not learned or experienced anything of value to you; if having worked with me for that session you think it is all a waste of time, then I will not charge you for the session - I have no wish to take money from anyone who does not feel they are getting value.

Beyond that it is really impossible to say: some cases which 'should' be easy can prove very stubborn while apparently impossible situations can show improvement in seconds. Although there are common symptoms, every situation, the reason for the problems, is different, and every reaction to a line of work is different.

Also, of course, there must be different criteria for success: someone who is three quarters blind need not feel cheated if they end up only half blind and with greater comfort, capability and confidence . . .

In fact, that is why I find the Bates work so interesting - because it is always different. If I wanted to do the same exercises every day in the same way I'd be an aerobics instructor. I would say that the common characteristic of clients who succeed with me is an open miind with a willingness to collaborate and explore, rather than passively expecting to receive treatment.

I am constantly prepared to be surprised, and rarely disappointed!
