Martzall’s clients have included equine athletes competing in world-class events such as the Land Rover Kentucky Three-Day Event, the Maryland 3/5, Fair Hill International, and England’s MARS Badminton Horse Trials and Burghley Horse Trials. He is an active member of the AFA, and his work spans a range of disciplines, including three-day eventing, dressage, hunters, and jumpers.
Martzall’s appointment advances New Bolton Center’s commitment to delivering exceptional veterinary and farrier services for all horses, from elite competitors and working horses to breeding stock and pleasure horses.
“Penn Vet’s New Bolton Center has long been recognized for setting the highest standards in equine veterinary medicine,” said Martzall. “I am proud to join New Bolton Center’s dedicated clinical team, where farrier services are an integral part of a holistic approach to keeping horses healthy, sound, and performing at their best.”
