We have a client who bought through Emma, he is one of the nicest horses I have ever met.
He made his debut in H&H last week - he is not your typical dressage horse to look at but he is very correct and incredibley trainable and regularly scores 70%+ in BD comeptitions.
She has a very good reputation and I did ring when we were looking but found something in the meantime. She was really helpful and very honest.
Only ever heard good things about them. Search reviews for sandalls farm as well if you want reviews, as that was what they used to trade under before changing personal situation.
