Leon graduated from Massey University in 1975, and has worked and lived in Howick for most of his professional career. In particular, a love of cats led him to study cat medicine further, and gain Membership of the Australia and New Zealand College of Veterinary Scientists in Feline Medicine. His greatest pleasure in vet practice has been the health and happiness of the human-pet bond, and the importance of pets in the family unit. Apart from feline medicine, Leon enjoys urinary tract medicine, canine medicine and general surgery.
Leon and Sue's children grew up locally and have now fled the nest. The eldest, a daughter, is a geography teacher in Melbourne, the older son a horticultural researcher in Sydney, and the younger son a production animal vet in the Waikato. Sue and Leon have a spoilt miniature poodle and similarly spoilt siamese cat. When not at work, Leon is a keen road cyclist, gardener and bush walker.
