After receiving her DVM degree in May 2012, she decided to further her training in the care of our beloved equine species and so completed an internship at Myhre Equine Clinic. She was recently hired on as our Associate Veterinarian for Ambulatory Services and is eager to provide our clients with the variety of veterinary services unique to horses out in the field. When not on the road, she is seen throughout the hospital, where she oversees in-patient care and assists our interns as needed. Her veterinary interests include equine internal medicine and lameness.
