We have a very experienced team of veterinary surgeons, many of which have been qualified for more than 14 years. Our vets undertake regular training and development courses to enable them to keep up to date with the latest techniques and medications. It is reassuring to know that there are very few things that someone at Hawthorn Vets hasn't seen before!

He also enjoys soft tissue surgery and is interested in endocrinology and oncology.
