I am a lightweight, 5ft rider. I do not get put off by the size of horse: I have ridden 11.2hh - 18hh. I will listen to what the horse is saying and constantly adapt my riding as I never expect every horse to be ridden the same way. It never worries me when a horse plays up.
I am happy to school, hack, jump and compete.
I have a strong belief that groundwork is the basis of good ridden work and shall sometimes advise that a horse revisit ground work to improve the riding. Therefore I can also work your horse in-hand, lunge, long-rein, free school and any exercise we know will help your horse.
