Sally Haddon is the beginner instructor extraordinaire! She loves the little ones and has a great deal of fun teaching them as they learn how to ride. She rode and showed western as a child and then became involved in hunter/jumpers when her two boys decided to jump ponies as well as dirt bikes. Her boys grew up at Chestnut Hills, and she began teaching to offset their expenses, and she loves it so much, she won't give it up. She also helps manage the daily projects and upkeep around the barn and she runs the summer camps each year.
