Mindy Coretz

Mindy Coretz

Owner & Trainer

A lifelong horse lover, Mindy began riding at 7 years old. 

As an amateur, Mindy established Eighteen Acres Farm, LLC through which she purchased, developed, and sold quality young horses. While balancing her sales business and college, she also sought out opportunities to ride under different top professionals. As an amateur, some of Mindy's accomplishments include wins and circuit championships at the Winter Equestrian Festival, National Hunter Derby wins, a class win in the AOs at Devon, and countless quality horses sold into homes where they continue to thrive. 

Since turning professional in December of 2016, Mindy has continued to seek out opportunities to learn and grow as a horse-person. Her diverse background of riding under and working for various professionals, her interest in managing the whole horse (including training and conditioning, veterinary and farrier care, feed and grooming, turnout, and so much more) set the tone for the horse-centric atmosphere at EAF. Mindy's love for horses is apparent and contagious through her program, which sets a precedent of putting the horses first at every turn. Since turning professional, Mindy has been successful in both the Grand Prix and International Hunter Derby arenas and shares her love and passion for both hunters and jumpers with her students. 

As a coach, Mindy loves working with people from all walks of life and is well practiced at helping students accentuate their strengths and work through their weaknesses in a positive and encouraging environment.

There, she double majored earning a bachelor’s degree in both Management and Marketing, along with a minor in Business Sustainability.

Over her years competing on the team, Hannah played a crucial role in winning three BIG IIX Conference Championships in a row, guiding her team to a record-setting season, and ultimately winning the university’s first NCEA National Championship.

Hannah was selected by both her teammates and coaches, as “Horsewoman of the Year”, five years in a row, an award that is given to one rider on the team that goes above and beyond, putting the care, health, and happiness of the horses first. Outside of horses, Hannah has a passion for the outdoors. Occupying her free time with hiking, fishing, and being a plant mom of her 25+ houseplants!
