Cory Gregory is very good, and has a lot of experience in bringing green ponies along.
I also ride strictly ponies but don't start.
Kelly It is rare to see a rider who is truly passionate about the horse and his training, taking a profound interest in dressage with self-abnegation, and making this extraordinarily subtle work one of the dominant motivations of his life.\"
Siobhan Byrne www.qualiadressage.com , a USDF Silver Medalist, starts ponies and horses under saddle. She is located in Maryland and trains out of my farm. She and I together are currently running a "special" young horse starting package which includes marketing said young horse for sale if desired at the end of the training period.
Teresa Butta in Maryland is also exceptional. She has been working with my pony for the past 4 years & has taken him from just started to winning at 4th level. Feel free to PM me if you'd like more information.
