I've been using the same woman for years and she has a really good background. Her website is www.centaur-therapies.co.uk Never heard of a lady called Anne Dee though. She has also got a column in Equi Ads.
I've been using this person for years www.centaur-therapies.co.uk shes got a really good background as well as she has brought out a CD has written a course for a college in animal communication and writes a animal communication column for horse problems in a horse magazine.
Sorry didn't realize I had replied before! I've met margrit Coates and found her to be a bit of an odd one. I found her to be good with horses but seems to have serious issue with interacting with people.
