I’ve watched the centre grow and further develop with great admiration as an outstanding multidisciplinary referral centre and general practice with the same commitment to excellence that has always been a byword for Willows. I look forward with enthusiasm to be working with such a stellar group of Specialists and superb veterinary and nursing talent to deliver the very best of care for the patients entrusted to our collective expertise by their owners and veterinary practices.”
