Sandy Glynn was raised in Connecticut surrounded by horses and horse people. Her father, Thomas B. Glynn, a lifelong horseman and polo enthusiast, is recognized in the Polo Hall of Fame.

Thomas Glynn went to look at Seabiscuit as a polo pony prospect before the small bay thoroughbred began his famous racing career and rejected him because of "a bad set of knees"...

Renowned artist and illustrator Paul Brown was an early artistic advisor to Sandy Glynn, but Sandy was drawn to the actual horses and became a professional rider at eighteen. She rode for many of the leading hunter jumper stables, developed a friendship with the five-time Olympian rider Bill Steinkraus, and was on the staff of the Moore County Hounds for many years.

Eventually she left the horse show world and foxhunting behind for the racetrack and became a successful trainer at the New York Racing Association tracks for several years.

Her art has evolved from these life experiences. Sandy Glynn and her husband, who is also an artist, breed thoroughbreds on their farm in South Carolina.
