Meaghan Dwyer

Head of Inpatient Care and Barn Manager

Meaghan began riding in Chelmsford, MA at 7 years old and immediately knew this was the road she would travel into and through adulthood. When she turned 10, Meaghan received her first horse, Prince. She worked as a barn hand and sought out knowledge, assisting Dr. Gaby whenever possible. She competed in IEA throughout high school and was the captain of her team in her junior and senior year. As a junior Meaghan competed in the Big Eq as well as the jumpers.

In her amateur years she continued showing jumpers but also enjoyed riding dressage with her mother. Her passion has always been working with young or untrained horses to build their confidence and skill as show horses. She is best known for her ability to train ponies, and her petite build has allowed her love of ponies to continue far past her childhood years. Most recently, Meaghan was the barn/business manager for a 47-horse show facility, where her charges received top-notch care.

Meaghan went through the life-changing event of requiring a kidney transplant. Although most transplant patients are advised to steer clear of farm environments, it was the need for equine contact and their reciprocated compassion that transformed her life to what it is today. In her free time, she enjoys pampering and caring for her mother’s 31-year-old, retired dressage horse!

Ally Govoni

Veterinary Technician

Ally began riding as a young girl and never looked back! Horses have been apart of every aspect of her life since. Ally grew up riding eventing horses until she found her love for reining. Attending college at Colorado State University, Ally continued to pursue her passion for horses and studied Equine Science. Being out in the west, it opened up lots of new opportunities for Ally that she had never dreamed of. After becoming the Breeding Assistant Manager at a 300,000 acre working cattle ranch in Wyoming, Ally’s natural talent for breeding and working with babies began to shine! After 5 very successful years caring for 80+ horses on the ranch and foaling out 30+ mares a year, she made the decision to start the road to becoming a vet.

Leading her back to the east coast of home, she continued her reining career and now has two quarter horses, Marilyn and Slim. You will almost always find Ally with her adorable Australian Shepherd named Wyatt around the barn and out in the field.
