Our story

The Cow Vets was established in a Cambridge garage in 1998 by husband and wife team, Chris & Kim Jolley, who understood the advantages that a small owner operated business could have on the ability to build relationships with farming clients. Dealing with the decision makers of the practice on a daily basis allowed for a more personal service and a better understanding of their clients needs. Chris & Kim grew the farm animal practice into a thriving business and started a small animal clinic as well. In 2005 another couple with a young family, Mark & Cathy O'Callaghan, brought the business. They have continued to grow both the pet and farm side of the practice, expanding farm services to Matamata and Morrinsville, and building a pet hospital in the centre of Cambridge. Their focus has always been on treating the business like family, with staff and clients often becoming friends and part of their lives. The original vision of a vet clinic that offers a caring personal service still drives us today.

He then spent two years locuming in England and travelling Europe with his partner Eleanor. In 2019 he returned to his home turf in the Waikato and a temporary calving job quickly became a permanent one, as he remembered how much he loved calving cows!
