Client Feedback

Having in the past had vets who had very poor communication skills and getting information was like pulling teeth! We now have vets who have very good people skills, they give information freely and keep us informed at all times. We have an excellent relationship with all of our vets, this comes when your practice is not too big and your customers have names not numbers. We are very grateful we made the move to The Cow Vets.

staff profiles

Mark O'Callaghan BVSc DipEnvAgSci DipHRM

Mark graduated from Massey in 1994 and has worked in dairy cattle practice in the Waikato ever since, apart from 4 years out for an OE. He purchased the Cambridge Pet vet & Cow vet clinic in May 2005, rebranding it and expanding the business to include 2 more clinics.

Patrick Taylor BVSc

A farmer’s son from Gordonton, Patrick graduated from Massey in 2015 and went straight into dairy practice in Canterbury. 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! Patrick enjoys working with farmers to improve cow performance and has a particular passion for surgery and condition scoring. In his spare time Patrick enjoys paragliding – he is currently having lessons with the aim being to offer a ‘fly in fly out’ veterinary service to suitable farms! He also has a passion for baking bread and training his new kitten Arcus.
