I’m so appreciative for John and Karen. I had a horse with a major wound that I’d been told there was nothing that could be done for. Dr. Marcotte took the horse in way after hours and had him taken care of in no time. The gelding stayed there for a few days and was treated as one of their own. I am so thankful for the professionalism and expertise of this clinic.

I have been looking for answers regarding old injuries and new lameness in my roping horse and after coming to this clinic I finally have answers! The staff here is very knowledgeable and kind, they didn’t rush and put up with all of my questions despite running behind schedule.
