Sheri 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 and starting with her first dressage clinic in 1983 with German master Col. Von Sighner and then 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 2 time Oylmpian 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. Sher'i's Grand Prix horse is now retired and she showed her 4 year old year old dutch mare "Champagne and Roses" with consistant high scores and wins at the FEI 4 year old level. She plans to show her this year at 2nd level and continue training with endless possiblities. Sheri continues to bring along her clients and their horses to reach their maximum potential both at home and in the show ring.

Sheri also is a certified life coach who specializes in sports performance enhancement and ways to alieviate anxiety 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 developement and mindset to set them up for a successful future.


Brandi Kingsmill


Brandi was born in Newmarket, Ontario and grew up on a small horse farm.  Horse crazy from an early age, riding English, Western, trail riding and dressage, she had several ponies and horses that taught her so much about riding and the love of the horse kept on growing. Accepting a job at Spruce Meadows, Brandi gained invaluable experience both in riding and breeding.

Moving back to Ontario for a brief period, with her now fiancée, Rob, Brandi worked on a Fjord breeding farm getting more experience with breeding and dressage.  Brandi has also groomed for several  well known jumper riders, gaining greater experience in the equine industry  and equine management.

In 2012 Brandi and Rob moved back to Alberta where she worked for a large breeding/cross country training facility but she soon realized her heart was in dressage and she chose to seek out a dressage barn to further her career.

Coming to Horizon in April 2014, Brandi has partnered with a wonderful Canadian Warmblood gelding named Hesston.  At their first show in 2014, Brandi and Hesston won both their classes with impressive scores of 69%.  Currently schooling second level, Brandi and Hesston continue on their path together to learn and grow. 

Brandi also has her certificate in Equine Massage and the horses love that part of her skill set. She is also an accomplished photographer.

Brandi is the perfect fit for Horizon. She loves the people, both students  and clients and  adds a wonderful  knowledge base of care and management of our horses,  as well as having a genuine interest in learning and advancing her riding career. She also has a love of teaching and helping others grow as riders.

Brandi runs our beginner/Intermediate level riding program as well as grooming for head trainer, Sheri Dumonceaux.
