Diamond U Berners

Cassie A.

Breeder of Bernese Mountain Dogs

Meet the breeder

I'm Cassie A., the breeder behind Diamond U Berners located in Nebraska. Alongside my husband and our 5 young kids, we've utilized our rural living and love for Berners to embark on a responsible breeding journey, to hopefully teach our kids a few of life's important lessons. We also hope to better the breed for future generations as well. Thanks for your interest!
