A third-generation equestrian from a polo family in Wellington, Florida, Mimi was raised on her family’s property with horses as her foundation. Influenced by her father’s work in breeding and starting young horses, she built a deep early education in horsemanship, groundwork, and individualized training.

Specializing in hunters, jumpers, and equitation, Mimi competed successfully on the Winter Equestrian Festival circuit and earned qualifications to the Medal and Maclay Finals. She gained valuable experience as a catch rider for top professionals, a working student at Fox Meadow Farm, and through competition at prestigious shows including Capital Challenge, Pennsylvania National, and Washington International. She credits mentors Kelly and Tim Goguen (Boggs Hill) and Havens Schatt (Milestone) for shaping her thoughtful, adaptable style.

Mimi is known for her exceptional feel and intuition with horses. Her greatest strength lies in reading each horse as an individual and crafting programs that develop them mentally and physically. She excels with sensitive horses, polished hunters, and hot or quirky jumpers, while thriving on transforming horses that need the right program to reach their potential. She is deeply hands-on with daily care, turnout, and management, and brings extensive experience importing and starting young warmbloods.

With a competitive background, comprehensive horsemanship, and a true horse-first approach, Mimi is dedicated to developing confident partnerships between riders and horses at every level. She is actively pursuing her USEF Small “r” judging credentials to further expand her expertise and contribution to the sport.
