You should, he is an amazing person and one of the most gofted riders and trainers out there. I learned a lot from a few lessons with him. Greg Best and Frank mMadden are some good ones to if u get the chance.
I don't know of Greg's. I took both clinics at Cindy Taylor's farm in Annandale NJ. Greg has also been hosting his clinic at Hidden Valley Riding Center in Cape May NJ
