I'm in N.Devon, already go to clinics with PH at TT's but need something a bit more regular + maybe, I feel, a new set of eyes!! willing to travel anywhere north of the moor! getting to the south is a bit of a trek for us!!
I have watched Sarah Cheetham and she trains CCJ's boss, and she always seems to get low dressage scores!
If she is coming near to you worth a try.
Chris Dannan is good with hot horses but not sure she is in your area, she tends to be Mid devon and southwards.
Or how about Alison Abbey at Duchy?
Lakefield equestrian have visiting trainers too, and I am pretty sure Adam Kemp comes down to Devon/Cornwall every two or three weeks.
Husband and daughter used to go to TT for PH, but husband's horse got a crack in it's foot and was off for 18 months and daughter went to local yard to train, so stopped going.
I'm in N. Devon and I have someone who lives in the same village as me and who has been my trainer for over 12 years. He is also at Grand Prix level himself.
I am going to be doing some clinics in October & November near Exeter and I visit a yard near Barnstaple every couple of weeks or so. Have a look at my website (on my profile) www.dressage.me.uk and get in touch if you think I could help.
Alison Abbey is lovely I have seen her lessons which are brilliant and she is very in the know about horses and her dressage. I truely recommend her she is a fantastic trainer ans a brilliant horse women.
