Head Groom

Shannon Maverick


Courtney hails from Charlottesville, VA, where she has been riding since the age of 5. She joined Pony Club shortly thereafter and is currently a C3 member. She started eventing at the age of 10 and has loved it ever since. After graduating from Liberty University in 2016 with a degree in sports management, she was a working student for Ellen Doughty-Hume for 6 months during the fall/winter of 2016. When she is not riding, Courtney enjoys watching baseball and college basketball, cooking, and hanging out with her dog, Riley. We are very happy to have Courtney back at Rockwall Hills Equestrian Center as the Assistant Trainer.
