TB Testers and Vet Techs

If you've had a TB test recently, you'll probably recognise these people! They're all Approved TB Testers (ATTs).

We also have a team of Vet Techs. Our Vet Techs work alongside you and our farm vets in a team approach to improve farm health.

She is a local dairy farmers daughter who has worked at home for several years on a new robotic dairy set-up. In her free time she likes to compete her horse and pick up on shoots with her two sprockers, Fig and Meg.
