Looking for Dressage Lessons in Indiana

I've been thinking for a while that I would like to take some Dressage lessons. I've been riding for 11 years and I started taking lessons(western mostly) again last year but I don't feel that I am progressing anymore and I need a new challenge. I know it's a long shot but I was wondering if anyone on here knows of any Dressage trainers or instructors in the Indianapolis, Indiana area. Thank you
