A friend of mine has had some trouble with Sally. The biggest problem is lack of communication, but I've also seen her sell a saddle which in my own opinion fitted neither the horse not the rider, and which she had to make a refund on.
I used sally a few months ago, i really liked her and she knew her job, she reflocked my saddle, watched me ride and commented how i ride with my pelvis tilted, which i never realised i did, but i could feel it.
I thought see went beyond being just a saddle fitter.
I have used her for years and been very happy, she seems to have phone trouble half the time but once I've got her I love her!
When I'd had kids she immediately spotted how I had changed my everyday posture and how it has impacted my riding.
My transactions with her have been a bit mixed. Some good, some bad. I understand she has now made improvements in her communications so at least you can get hold of her, which was a major issue before. Feel free to PM me for more detail.
