Mark Wasserman

Mark Wasserman – Owner and Founder of Equi-Stem LLC

Mark Wasserman has been an active owner of Standardbreds for more than forty years. Currently, he races and breeds his Standardbreds under the stable name of Fiddler’s Creek Stables LLC, and is stabled in New York.

Inspired by a conversation with his daughter after his grandson’s birth about the benefits of preserving umbilical stem cells for current and future uses in regenerative medicine, Mark created Equi-Stem to bring these same benefits to the equine industry. After opening Equi-Stem LLC in 2014, the company has quickly become the leader in equine stem cell preservation of umbilical cord tissue and is proud to have the country’s most prominent professionals in regenerative medicine on its staff.
