I teach at Sprout because horses have always been a way for me to live in the moment and forget about my struggles. Horses have inspired me to grow both mentally and physically and I want to be able to facilitate that feeling of pure joy and personal growth for my students.

Lacy Warner

PATH Intl Therapeutic Riding Instructor

Lacy grew up in Upstate, NY in the Hunter/jumper show ring. As a teenager she acquired her first horse, a very difficult off-the-track thoroughbred, who eventually necessitated an introduction to natural horsemanship. After seeing the possibilities this new world of horse training could provide, Lacy began retraining her horse, and herself, via Parelli Natural Horsemanship. She graduated Parelli level 3 in 2011, after spending time at both the Florida and Colorado Parelli campuses, and makes a great effort to attend continuing education courses on a regular basis. Moving to Virginia was the best thing that ever happened to her! For many years now she has taught riding lessons to children and amateur adults with a focus on riding confidently cross country & fox hunting in addition to showing and eventing. She believes good training should be based on proper ground work and flat work.

Lacy’s passion is to show people that they can achieve their riding dreams, whatever they may be and to open their eyes to many different equine disciplines. She also takes great pride in training/re-training and starting/re-starting horses. Lacy can often be seen in the hunt field with a trail of children & adults with her. She has her colors with both Warrenton and Loudoun Fairfax hunts after nearly 15 seasons combined.
