If you are an AQHA/APHA or (gasp) Appy person, I don't think you could find a better instructor within an hour of here. I saw her work with someone on a youngster and I can tell you that when I can start with lessons again...she will be my local trainer as my main trainer is over 2 hours away
I think Donna does a wonderful job, she has been a great help with Turbo. And the barn is ALWAYS neat, clean and organized which I love.
