Mr. Williams is no longer in Delaware and is now closer to the Cleveland area, I understand. My trainer, Leslie McDonald, is in the Cincinnati area and is USDF gold medalist. She is at Full Cry Farm in Batavia Ohio.
There's a few good one's in Cleveland area (eastside). Nancy Lewis Stanton. On FB her farm is Sendonway Farm. Also there is Elena Sokolovskaia, she can also be found on FB. Charlotte Bailey and Nancy Smith are a few other good local trainers. We also have Kate Poulin!!! She's at Fair Weather Farm. Her information can be found on FB under Poulin Dressage. Hope this helps?
Fallon and Kelly Walker outside of Cleveland. Both were selected to ride with Edward Gal and Fallon did. Kelly's horse became ill before the clinic and could not go. They run a great place at Truly dancing dressage and would do a fine job.
