    Licensed Veterinary Technicians and Veterinary Assistants

    Our dedicated technicians and veterinary assistants are responsible for a wide range of duties and assist our veterinarians in nearly everything they do. A typical day may include daily rounds and treatment of hospitalized patients, animal husbandry, assisting in radiography, admitting and discharging patients, preparing for and assisting in surgeries, monitoring anesthesia, lab work, dentistry, ICU monitoring, artificial insemination, stallion collection, foal watch as well as supply and inventory control. You may frequently speak with one of our technicians or assistants in absence of a veterinarian to review discharge instructions, lab results and patient progress. Perhaps you’ll meet one of them in person as they will frequently travel and work with the veterinarians in the field.
