William's educational presentations and articles are wide ranging, covering all equestrian disciplines and coach education for all sports. In particular his innovative structures for improving performance,
The GO! Rules and The Winning EDGE, have received wide praise. His book, The Complete Horse Riding Manual (Dorling Kindersley - 11 languages) is the best selling riding manual in the world, and his more humane Micklem Bridle is the best selling bridle in the world.
He found Karen and David O'Connor's three Olympic horses, Biko, Custom Made and Gilt Edge, and is the breeder of two other Olympic horses, Mandiba and High Kingdom. He also bred their full brother,
the stallion Jackaroo. He is a Fellow of the British Horse Society. He has received lifetime achievement awards for his breeding successes from Horse Sport Ireland and for his coaching from Eventing Ireland.
"In the proverbial 101 ways, William Micklem has made huge contributions to the manner in which we ride, train, equip, breed, and think about horses. His positive impact spans oceans, disciplines and breeds of horses. If William speaks or writes about it, go listen or read it." Denny Emerson USA event Team Gold medallist, USEA Hall of Fame, best selling author, and chair of breeders committee of AHSA.
"William Micklem is one of the best minds in the horse world today. He has a unique mixture of practical experience at the highest levels and thorough knowledge of classical principles of horsemanship. Anything William says is worth hearing." Jimmy Wofford USA double Olympian, leading Coach and Author
"I first met William when I was thirteen years old. It was exciting for me to learn classical dressage from someone whose passion was eventing, and it was apparent, even then, that William's teaching philosophies were ahead of their time. William has studied horse and human behaviour all his life and has mastered the relationship between the two. His teachings became the foundation for my riding and his horsemanship continues to be the flagship of our training programme." Karen O'Connor Five time Olympian and nine time USA Female rider of the year. From her introduction to William's book, The Complete Horse Riding Manual.
