Jessica Black grew up riding and showing Morgan horses. She was introduced to Spanish doma and rode pure Spanish-bred and Lusitano horses while studying in Spain. Later, she spent several years training, galloping, and racing Thoroughbreds and Arabians as an amateur in Spain, and galloped Thoroughbreds and Quarter Horses in Mexico and Panama. She earned an MA in Psychology from Humboldt State University and is currently pursuing her Doctorate at the University of Oklahoma. Her research is focused on the intersection of narrative and morality.

Eitan and Debbie Beth-Halachmy founded Cowboy Dressage and have devoted their lives, their Morgan horses, and their Wolf Creek Ranch in Grass Valley, California, to spreading the movement's ideals of lightness and kindness as reward in training.

Photographer Lesley Deutsch is a lifelong horseperson. She operates Blue Mountain Farm, just a few miles from Wolf Creek Ranch.
