Horse first. Always.
Our mission is to develop sound, confident sport horses through relationship-based training, biomechanical correctness, and uncompromising care—prioritizing longevity, trust, and excellence in every partnership.
Performance
and Soundness
for the Modern Sport Horse
At the heart of our work is a belief that true equine wellness comes from supporting the whole sport horse—body, mind, training history, and environment. For over a decade, we have helped jumper and dressage horses regain soundness, confidence, and clarity through thoughtful, individualized care.
Our approach blends biomechanics, evolving veterinary science, and rider expertise, with an intuitive understanding of how posture, movement, and the nervous system affect performance. We specialize in horses often labeled as “difficult,” “sensitive,” or struggling with so-called mystery or body lameness—many of whom arrive as last-resort cases and go on to return to successful work and competition.
By restoring balance and correct movement, we help create resiliant, willing sport horses and partnerships built on trust, longevity, and harmony—allowing horses to thrive in both the show ring and their everyday work.
Located on a quiet country road in East Chatham, NY, Pine Hill Farm is surrounded by rolling hills in the hamlet of New Concord. The farm offers everything you need to further your training and enjoy your horse in a peaceful setting—free from the hustle of busy lesson facilities or public barns. Conveniently close to Albany, Chatham, Ghent, Hudson, and the Berkshires, top veterinary care, bodywork, and major shows are all within easy reach. Family-run and owned by Katrin and her husband Paul-Ivan since 2022, Pine Hill Farm is thoughtfully managed with sustainability and a healthy ecosystem at its core. Here, horses are allowed to be horses and reach their full potential as sport horses.
Our Story…
Where horses live naturally, thrive as athletes, and develop their full potential. A serene, private setting for horse-first training, boarding and high-level sport.
