Animals and livestock are an asset to land and soil health when treated holistically. We offer services and a philosophy that complement these management techniques.

When livestock are managed in a way that regenerates soil and plant health, all will benefit. Our veterinary and livestock management consulting services complement this approach.

We take into account a multitude of factors when treating animals, as they are part of a larger system that includes and impacts the land they live on, their herd dynamics,

and their caretakers.


We strive to make genetic improvement tools accessible, allowing us to improve genetics built for our environment. We can maximize our genetic potential and achieve a phenotype

that truly thrives in our micro-environment

and management situation.
