About Us

Horizon Equestrian CenterSheri Dumonceaux has been involved with horses her whole life. She started riding when she was 10 and spent the next 12 years riding hunters and jumpers in Ontario. Her first glimpse of dressage captured her attention. Starting her first dressage clinic in 1983 with German master Col. Von Sighner, she was hooked! “A major transformation took place,” she remembers, “I saw how horses could be ridden, happier and more supple. He made them dance and I wanted to ride like that!”

Sheri began to train with Betty Jean Hutton, a well-known dressage trainer in Ontario and became an avid student of the sport. Following a move to Calgary in 1989, Sheri continued to study with Betty Briggs in Edmonton, who she considers a mentor and guiding light. “Betty is a fabulous rider and a huge help to me because she really understands the technical side of dressage and explains it so well.”

Sheri then started training with Canadian Olympic team member Tom Dvorak in 1997. Working with Tom has been a wonderful experience for Sheri. “I feel he has added a new dimension to my riding and improved my focus”. Tom Dvorak comes to Horizon 4-5 times a year to give clinics.

A two-time Olympian and a recent Silver medalist at the Pan Am games in Mexico, he is an excellent teacher and trainer who compliments the program at Horizon so well. Sheri’s Grand Prix horse is now retired and she showed her 6 year old year old Dutch mare “Champagne and Roses” with consistent high scores and wins at the FEI 8 year old level. She plans to show her this year at her PSG show in 2016. Sheri continues to bring along her clients and their horses to reach their maximum potential both at home and in the show ring.

Sheri is a certified life coach who specializes in sports performance enhancement and ways to maximize success in the show ring.

Sheri also starts many young horses for the sport of dressage in a correct manner that gives the horses the correct muscle development and mindset to set them up for a successful future.
