Jay Em Ess Stable is named for the first initials of Samantha Siegel and her late parents, Jan and Mace. Jan died on April 4, 2002, and Mace passed away on October 26, 2011.

Samantha, a pedigree and conformation expert who is active at many sales throughout the nation, is continuing the family stable with the blue and lime green silks and cleverly-named horses. 

Mace and Jan met on a blind date at Aqueduct in 1962 and bought their first horse in 1964. Samantha was named for the song, “I Love You, Samantha,” a favorite of Jan’s, a former big band singer. Mace was the founder and owner of Macerich Co. of Santa Monica, which develops, owns and manages regional shopping malls. A powerful and respected owner-breeder in California racing, he co-founded Thoroughbred Owners of California.

Include Me Out became the stable’s latest Grade 1 winner in the 2012 Santa Margarita Stakes. Jay Em Ess earned an Eclipse Award with unbeaten champion 2-year-old  male Declan’s Moon in 2004 and won the 2009 Hollywood Gold Cup with Rail Trip.

Jay Em Ess Stable owns two 2016 Breeders' Cup contenders: Pat O'Brien Stakes winner Masochistic (Las Vegas Dirt Mile) and Bed o' Roses Handicap winner By the Moon (Filly and Mare Sprint). Jay Em Ess co-owns Masochistic with Los Pollos Hermanos Racing.
