David graduated in 1980 from the University of Queensland and spent 20 years in private veterinary practice in Australia and the United Kingdom before deciding to pursue a career in counselling and personal development. He worked initially in mixed practice then mostly in small animal practice. His special interests during his time in practice were emergency medicine, orthopaedics and dermatology.
From 1999 until 2001 David trained and worked in general and crisis counselling with Lifeline and also completed bereavement counselling training at the Bereavement Care Centre in Sydney. During his time in practice David noted the extreme difficulty and lack of support many clients experienced when trying to cope with the death of their pet. He also became aware of the difficulties many veterinarians, from new graduates to seasoned practitioners, experienced when trying to cope with the complex demands and stresses of practice life.
