Our Team


Sarah Low dvm

Director, President

Sarah Low is a veterinarian with a passion for improving equine welfare.  Prior to receiving her Doctorate of Veterinary Medicine from the Virginia-Maryland College of Veterinary Medicine, she earned a Bachelor of Science from the Massachusetts Institute of Technology in 2003 and spent several years working in the film and television industry as well as training horses and teaching riding lessons.  In 2006 her special interest in wild horse welfare and behavior began when she spent time in Hawaii trapping and handling feral horses on a large cattle ranch. This experience was the catalyst for becoming a veterinarian and has heavily influenced Dr. Low’s desire to improve ways wild and feral horses are gathered, handled and managed. After graduating from veterinary school in 2015, Dr. Low completed a research training fellowship in equine behavior and welfare at the Equine Behavior Lab at University of Pennsylvania, New Bolton Center. During this fellowship Dr. Low designed and tested an equine handling welfare audit system for use at BLM wild horse and burro adoptions.  In October of 2018, Dr. Low purchased two sales authority mustangs from the BLM and began gentling and training them using protected contact and positive reinforcement.  Dr. Low uses photo and video documentation of her training and handling process with these mustangs to share and teach positive methods for handling any horse, even wild ones. She believes education is vital to improving equine welfare as well as handler safety.

Sue Mcdonnell phd

Director, Secretary

Sue’s interest in low-stress handling of animals goes way back to when she grew up on her family dairy farm.  Her father was adamant about quiet, respectful, non-confrontational handling of livestock.  Her 4-H activity was training and showing dairy cattle. 

Sue’s undergraduate and graduate studies included human psychology and then animal physiology and behavior.  She holds Animal Behavior Society Board Certification as an Applied Animal Behaviorist. 

Sue’s professional career has been based at Penn Vet's New Bolton Center, where she is Founding Head of the Havemeyer Equine Behavior Program.  There her work includes clinical, research, and teaching in equine reproduction and behavior, with particular expertise in stallion reproductive physiology and behavior.  She also teaches horse handling and safety, equine welfare, as well as basic and clinical horse behavior for veterinary students, staff, and veterinary continuing education.  For over 25 years, her research program has maintained a semi-feral herd of ponies living under natural social organization, as a model herd for study of natural horse behavior. 

All of this experience together with her knowledge in ethology, animal learning and cognition, has fueled her fervent interest in promoting state-of-the-art low-stress, safe, and efficient handling and training of horses, domestic or otherwise.“When it comes to the capture and handling of wild horses and burros we need to support and celebrate every little step in the direction of low-fear, positive human-animal interactions.”
