Janet Naylor

Janet got her first horse when she was 13 year old. Since moving to her family’s farm in 1982, Janet has been an avid dressage rider and competitor and breeder of Warmblood sport horses. In 1991, Janet graduated from the University of Guelph with an honours Bachelor of Science in Biology. In 1996 Janet was married to her husband John, and an indoor arena was built at the farm. The emphasis at the farm was then switched from a breeding operation to a boarding operation where Janet started coaching dressage, and has coached dressage for the past 20 years. Janet has coached many students at the trillium (silver) level of dressage and has shown and trained horses at the Prix St. Georges level.


Janet has always been interested in veterinary medicine and in 2014, she successfully completed one full year of the Veterinary Technology program at the University of Guelph, Ridgetown. Janet then worked for a year at a small animal veterinary hospital as a veterinary assistant. We are pleased to have her join our team.
