Mary Motion joined McMahon & Hill Bloodstock in 2025 as Director of Business Development, bringing a strong background in both training and bloodstock to the team. In her role, she oversees marketing, client and partner engagement, and communications across Bourbon Lane Stable and McMahon & Hill’s various racing and ownership ventures, including partnerships, pinhooking LLCs, and single-horse co-ownerships. She is also an active member of the bloodstock team, assisting with research, purchasing, and sales, as well as helping manage horses in training.

​

Originally from Virginia, Mary grew up immersed in the Thoroughbred industry and was a steeplechase jockey throughout her teenage years, developing an early, hands-on understanding of horsemanship. She has since worked for some of the sport’s most respected horsemen, including her uncle, Classic-winning trainer Graham Motion, Christophe Clement, and international bloodstock agent Chad Schumer. She has also gained valuable international experience working for leading trainers and farms in England, Australia, and New Zealand.

​

Most notably, Mary spent time in England with Oliver Sherwood during the training of Grand National winner Many Clouds. In Australia, she worked with Ciaron Maher, where she rode multiple Grade 1 winners in the mornings and played an integral role in helping manage the stable. Alongside her professional experience, Mary has also developed a successful personal record with her own pinhooks. Those investments include purchasing a weanling for $3,000 that she subsequently sold in Ireland for €90,000. Another horse she pinhooked went on to win the G1 Qatar Derby. These results, combined with her international training and bloodstock experience, give Mary a unique understanding of the ownership journey, from identifying and acquiring horses at auction to developing them and ultimately realizing their value on the sales or racetrack.

​

As the main point of contact for current and prospective partners, Mary is dedicated to providing clear communication, hands-on support, and a personalized experience for every client. She also leads the marketing and communications efforts that help tell the story of the stable, its horses, and its partnerships. Her goal is to make Thoroughbred ownership more accessible while upholding the quality, transparency, and results that define McMahon & Hill Bloodstock and Bourbon Lane Stable.
