Thomas Clark became a student of pedigree and the bloodstock markets at an early age while growing up near Saratoga Springs. His first professional job was with a large commercial breeding operation in Middletown, New York starting with mares and foals where he remained with increasing responsibilities until accepting a position with an established bloodstock agent in Lexington, Kentucky.
Mr. Clark started his own bloodstock agency which he operated until John R. Gaines offered him the position of Bloodstock Consultant during formation of his new venture, John R. Gaines Thoroughbreds, in 1993.
In 1995 Thomas Clark Bloodstock LLC was formed and continues to provide international consultant, brokerage and bloodstock management from offices in downtown Lexington, Kentucky
