About TME

As an owner, trainer, and breeder for over 44 years, I know horses and I love them. I currently own 41 head. They are my passion and a part of my family’s everyday life.

That’s why I created Thunder Mountain Equine. Anything similarly named is a counterfeit and a rip-off. My “Sandy’s Formula” is the original developed over the course of many years of painstaking research and trials. My horses are my laboratory.

I’m a lifetime member of AQHA and APHA and have competed or worked in barrel racing, reining, cutting, western pleasure, team penning, reined cowhorse, sorting, ranch work. jumping, racing, dressage (years of lessons in Europe), and as a vet tech. I’ve been around riders and owners who have witnessed firsthand the results of the original Thunder Mountain Equine (TME) essential minerals supplement.

Owner and Outfitter - West Jordan, UT

"Thunder Mountain Equine has done a fantastic job of increasing my paint's hoof growth and the speed at which he grows his feet. He can build his heel better and he's sound and stable. TME has taken a 20-year-old and what could have been useless horse, and turned him into a 20-year-old fantastic, sound horse."
