Dr Jamie Lines was raised on a farm in Victoria, Australia. He earned his Veterinary Science degree from the University of Melbourne in 1994. His first job was in an dairy oriented practice for two years, followed by some locum work in Australia and the UK. He returned to Australia where he and his wife purchased a dairy farm while he continued to work for local veterinary practices.

Jamie then made a career shift and trained as a mortgage broker, earning a Graduate Diploma in Applied Finance and Investment. He founded a financial planning business on the Gold Coast, which dissolved during the financial crisis a few years later.

He found his way back to veterinary medicine, doing locum work and also traveling in Southeast Asia with his family. He and his wife founded a veterinary clinic in Alice Springs in the Australian outback, while Jamie completed CIVT’s Graduate Diploma of Veterinary Chinese Herbal Medicine course and an introductory Western herbal course. His latest professional activity has been offering integrative therapies from two small animal clinics on Australia's East Coast.
