Allison Houston did a remarkable job of taking the concepts of Charles Wilhelm's foundation training and making it clear, concise, and easily understandable for a wide range of equine enthusiasts. Riders from any discipline can benefit from the training concepts/methods presented in this book. I hope to hear more from Ms. Houston in the future!
