I use a guy called Robin Harding who actually lives in Cheshire, is EDT/ETD (can't remember which way around it is) registered... I can give you his contact details if you are interested. He travels up to me in Lancashire...
Craig Griffiths 07773064931, lives near Northwich. He is excellent but if you want a yard visit he is usually booked up for 2-3 months! A better option is to meet him at Brown Moss Equine Clinic (Burgess & Graham).
