Here are a few of our most amazing instructors.

Mackenzie Parks

Justin Haefner

Justin Haefner, partner and trainer of Riding Far, LLC, specializes in the training and handling of young performance horses.

He rode his first horse at 2 years old and has committed his life to horses since. He is passionate about studying classical dressage and the teachings passed on by students of Ray Hunt and Tom Torrance. This combination has led to the belief that it is essential to understand how horses’ function physically, as well as how they think and feel, in order to effectively communicate with them.

Justin committed to transforming the experiences of horses and their riders through his work with his business partner and father, psychologist Dr. Paul Haefner. Justin’s knowledge of horses in combination with Paul’s knowledge of humans provides a basis to create powerful opportunities for riders to transform their relationships with themselves and their horse in large and small ways.

Lisa Barry

Lisa Barry is a 5 star event rider who has been riding since her mom was pregnant with her. She’s been through pony club and young riders and has trained under Karen O’Connor for 30 years. I’ve produced 35+ horses that started from homebreds to OTTBs to difficult rides and everything in between. She loves all horses and enjoys being able to share her compendium of knowledge she’s been lucky enough to learn along the way. She teaches in a very positive and progressive way no matter what your goals.

Woods Baughman

Woods Baughman is a 4 star rider and assistant trainer at Last Frontier Farm with Sharon White.   From Lexington, KY, he started riding at age 6 with Maggie Wright at her Champagne Run Farm.

Suzanne Liscouski

Suzanne Liscouski, owner and trainer of Briar Creek Farm, grew up in the horse world the traditional way; pony club as a child and competing in local, state and regional equine events in her home state of Connecticut.

Given her passion for horses, she attended Sweet Briar College in Virginia, renowned for their Hunter Jumper program. A horse owner since the age of 10, Suzanne’s life forever changed when she started her first colt with Ray Hunt in 1999. From that moment forward, her methods and riding philosophy have been focused on giving the horse a “better deal,” as Ray taught. At Briar Creek Farm, Suzanne can now focus on linking these principles to any and all disciplines, such as English Hunters, Dressage, Western, Western Dressage, jumping, trails/obstacles and Working Equitation. With her methodology, you will be able to link the skills taught by horsemen with whom Suzanne has studied over the decades to your specific equine goals. Hence, the business name was born for Briar Creek, “The Foundation Link.”

The concept of The Foundation Link means doing more with less, making your horse a willing partner, and approaching training in a way that builds confidence in the horse and in the rider. You do not have to be a cowboy to adapt these foundational methods to your discipline; rather, this holistic approach provides a solid foundation to develop confidence, safety, and a true connection with your horse.
