The Four Sixes Ranch offers a paid internship for undergraduate college students looking to advance their knowledge and skill in the equine industry, with the potential for full-time employment if available. Whether you are interested in applying to vet school, or simply learning more of the basics of general care, reproduction, foaling, doctoring, vaccinations and sale prep of horses; this is an internship you should consider. You will get a tremendous amount of hands-on experience and on-the-job training.

The Four Sixes Ranch has a state-of-the-art facility with advanced technology, a surgery suite and diagnostic tools to offer outside clientele and to be used on the nearly 1000+ head of horses currently on the ranch.

We stand approximately 24 stallions for on-site and cooled/shipped semen for artificial insemination, and breed around 1500+ mares annually. We are also a Select Breeders Services (SBS) affiliate lab for stallion freezing, and breed many mares throughout the season with frozen semen. Embryo transfer and embryo freezing are yet another service we routinely perform.

A positive attitude and good work ethic are required and in turn, we will provide a professional working and learning environment. Several positions are available for two different internship options. Depending on your school schedule or work availability, we can evaluate your situation on a case-by-case basis.

Interested applicants should send or e-mail a cover letter, resume and references to:
