We pride ourselves on giving partners first-rate expertise and service — both on and off the racetrack — while maintaining a boutique, familial character.

Eclipse Thoroughbred Partners is led by Aron Wellman, a licensed attorney in the State of California and lifelong horseman, and Brian Spearman, a 32-year PepsiCo Executive and lifelong horse racing fan turned professional. Aron’s professional experience and hands-on horsemanship skills, combined with Brian’s business acumen and enthusiasm for the game create a unique synergy for the partnership.

Kelsey Marshall Hughes wears many hats as the only other member of the team (along with Aron) who has been with Eclipse since the company’s inception. Kelsey has been characterized by many Eclipse partners as “the glue that holds the operation together” and her many talents are appreciated by all partners who work with her on a frequent basis.

In 2012, we had the great honor of being selected by Cot Campbell, the legendary pioneer of racing partnerships, to merge with his iconic Dogwood Stable and serve their clientele upon Mr. Campbell’s retirement. The merger not only conferred on Eclipse the ultimate endorsement — it brought Jack Sadler and Bill Victor onto the Team.

Jack Sadler served as Mr. Campbell’s right-hand man for nearly 3 decades, and is a brilliant horseman and legitimate “Jack of all trades.” He serves as Eclipse’s Vice President of Operations.

Bill Victor essentially invented racing-partnership accounting, bookkeeping and tax compliance during his 20+ year tenure as Dogwood’s Treasurer. As Eclipse’s Chief Financial Officer, Bill is an invaluable asset to the operation and its partners.

In 2022, we added a key player to our team, Sean Tugel. Sean brings to Eclipse a vast depth of experience, having worked in various capacities for some of the most esteemed operations in the industry while learning from some of the smartest players in the game at Hill N Dale, WinStar and Gainesway Farm. Sean serves as Eclipse’s V.P of Bloodstock and will be based in Lexington, Kentucky, which will complement Eclipse’s offices in New York, California and South Carolina.


Our model is designed to be efficient while maintaining the unparalleled service and quality our partners deserve.
