A new approach to equine care.
Superior care. Premier experience. Unmatched convenience.
At Teton Equine, our ambulatory practice is designed to optimize the patient and client experience. Our veterinary professionals come to you and our mobile clinic is designed with state-of-the-art diagnostics, built-in laboratory equipment and stocked with medications, enabling us to provide unrivaled testing and advanced treatment options for the majority of equine medical and surgical needs. The result is increased convenience for our clients, and the highest quality on-site care for our patients.
Unlike traditional, clinic-centric models that prioritize speed and number of patients seen per day, our protocol is designed to ensure that our clients are given a personal world-class experience tailored to their individual horse. Our ambulatory model maximizes the time we spend with our patients in their home and natural environment, providing them dedicated, individualized care.

When not tending to the horses, she can be found hiking with her dog, playing tennis, or enjoying the great outdoors.

Alisson Young
Veterinary Assistant
Allie grew up in the state of Washington where she fell in love with horses at a young age, as a little girl she participated in 4-H and began showing horses in the Paint Horse Circuit. Her passion didn't stop there, Allie bred and raised quarter horses that she trained and shown within the reined cow horse world. However, over the last couple years horses have taken a back seat as Allie has focused her energy on raising her two amazing sons and creating her own little family. But now that her two sons are older and turning into young gentlemen, Allie plans to return to her lifelong passion and has begun to breed and show Appaloosa horses! Allie has spent many years working in the field of veterinary medicine as a technician for multiple different equine veterinary practices and the horses seem to feel right at home with her! She has a gentle and calming way with horses that puts their nerves at ease! She is excited to continue expanding and developing her knowledge of equine veterinary medicine here at Teton Equine.
When Allie is not working she enjoys spending her time with her family and trail riding in the mountains. She has also fulfilled another lifelong dream of hers- raising Scottish Highland cattle and boy are they adorable!!! Currently, Allie's herd consists of 30 head!!!!! And with the help of her husband, together they ranch and raise several highland calves a year! They plan to continue growing their herd and follow their dreams of living the farm and ranch lifestyle that has become so rare these days! We feel very lucky to have found Allie and are so happy she is now part of the team!
