Very professional and dialed in. Screens the horses really well. Last year I participated in the Diamond in the Desert Sale and bought one of the best horses I have ever owned, and I have owned plenty! The horse was exactly as advertised if not better. MM Auction screened these horses really well and was helpful from the purchase to the delivery. I was not able to attend last year and bought the horse via the internet with no problems whatsoever. This year I will be there. It will be hard to find another horse like the one I bought last year, as he is one of those “once in a lifetime” horses, but if there is another one chances are he will be at the Diamond in the Desert Sale.
