Tammie worked at several stables in England, and eventually worked her way up to managing the yard at "The Manor" where she trained polo ponies, competition horses and oversaw the breeding program. In 1997 she moved to Canada to be with her husband David, and started working with Unicorn Stables as the barn/facility manager and coach. Since 2011 she has been living her childhood dream as the proud owner of this ever improving, first class facility. Tammie competes her horses in both Canada and the US,and enjoys coaching at events as well. Unicorn Stables is home to a few of Tammie's past competitive mounts, and they now help to teach the next generation of riders.

Since then she has enjoyed volunteering her time with summer camps, birthdays, and many other events. Kasandra has competed locally in a variety of horse shows, as well as participating in Pony Club up to her C1 level.

Cassidy Kerfoot

Cassidy began riding when she was 5 years old at a Hunter/jumper barn before moving to Unicorn and discovering her love for Eventing. Here she leased and competed different horses over the years, including her first horse Sugar, who she leased when Sugar was a school horse before purchasing her. Together they competed successfully at training level in both Canada and the USA. While moving up to Preliminary level, Sugar sustained an injury, and is now retired happily in a field, but she will remain with Cass for the rest of her life! At the end of 2018, she got a new horse named Beckham, who she hopes will take her to the upper levels of Eventing in the future. Cassidy was a part of Pony Club for many years where she obtained her B level. She also took courses in Equine Studies with the University of Guelph in equine management and behaviour. Cass is excited to continue her journey with horses and to be on the Unicorn team to help teach upcoming riders!
