Jessica wears a lot of hats at Peridot: barn mom, lawyer, HR director, cheerleader, decorator, event planner, graphic designer and branding fanatic, marketing/PR, construction foreman and poop scooper. Some days, she just calls herself a Gladiator who champions this amazing barn family, the horses and our beautiful facility.

Jessica has been passionate about horses since she was 2 years old, and has been riding since her aunt bought her a horse when she was 8 years old and her parents were away on vacation.

She fell in love with Dressage in her 20s, but didn't really get the time to pursue it until her daughter, Kate, decided she loved it too. There are many days that Jessica thanks her lucky stars her daughter didn't prefer a different sport like soccer. It has given Jessica the chance to fully immerse herself into not only her own passion, but her daughter's.

Jessica is also an amateur rider, who dreams of showing at the FEI level and winning a national championship. For now, she is loving every minute of being on a horse farm every day. It is a childhood dream come true.
