Shelby Dehne

Shelby has been studiously increasing her knowledge as a horseman from an early age and has been following her passions ever since. She has a solid grasp of the biomechanics and skills that separates great riders from the rest. Her diversified experiences have given her a depth of knowledge uncommonly seen in an equestrian so young.

Throughout out grade school, Shelby showed horses in her local 4-H and FFA fair and later went on to compete in the Central Pennsylvania Youth Rodeo Association (CPYRA) for many years. She was a 2008 CPYRA Rodeo Finals Qualifier.

In her collegiate years, she switched her focus from competition to training, particularly in colt starting and the discipline of reining, to better understand how great horses and riders were made. Her thirst for knowledge opened her to a wide network of equestrian professionals. She spent many years training under the supervision of Jason Charles and then went on to complete an apprenticeship under Josh Miller. Miller was a Team Schmersal Trainer at Craig Schmersal Performance Horses for many years before relocating to Pennsylvania. Shelby credits Miller for her refined knowledge and skill in training young horses and riders alike. Shelby was then offered an Assistant Trainer position at Chapman Reining Horses. Due to collegiate constraints, she unfortunately had to turn down the position. Shelby was later employed by Ashcombe Sporthorses at Flower Farm as an Assistant Barn Manager. There, she had the opportunity to work with some of the finest bred KWPN horses on the East Coast.

Since graduating from Towson University in 2016, Shelby has relocated to Delaware. On the weekends, she teaches lessons focusing on skill development. Her unique experiences as a horseman directly correlates to her talent as a riding instructor. Her prerogative is to instruct and inspire confidence, collection, and safety in each one of her students.
