VSS grew rapidly in the first 5 years. The practice at Compton Road encompassed a 400sqm floor space, with another room across the car park that contained a CT machine and underwater treadmill. The CT was the second CT machine in veterinary clinical practice in the southern hemisphere.
Dr Terry King joined the practice as a partner from the University of Queensland teaching hospital in July 2002 (small animal medicine/emergency and critical care), followed by Dr Jason Mouatt in 2006 (Small Animal Surgery), when he returned to Queensland from Melbourne. Both Terry and Jason retired as partners but remained involved in the practice and profession for many years.
Lindsey Connell joined VSS and established an Animal Physiotherapy practice in 2003. Dr Peter Barron joined the internal medicine team as a registrar and subsequently sat his Fellowship exams. The nursing ranks also swelled with Anita Parkin (now Employee Engagement Officer), and the two Karens (Kemp and Kelly), along with Linda Coad joining VSS. Fiona van de Linde and Sue Moore also joined VSS in this period.Dr Brad Gavaghan offered a mobile cardiology and imaging service in Brisbane, and his relationship with VSS began in 2001. Dr Gavaghan has performed interventional cardiology procedures since the early days of the practice.
The Compton Road site had rapidly outgrown its footprint, and new premises were sought in Brisbane and the Gold Coast. The VSS intern program started in 2006 with Dr Kisa Baldwin and, in 2007, Dr's David Cook and Wendy Agnew were part of the intern cohort and are still with the practice today. VSS has had more than 125 interns since the program began. The intern program blossomed into a residency system and many VSS interns have gone on to achieve success in general practice, specialist qualifications and further studies (such as PhD qualifications), or become zoo veterinarians and senior government veterinarians, among many other paths.
As of December 2020, more than 35 veterinarians have been through specialist training while working at VSS, or entered a training program after being a VSS intern. Anita Parkin has pioneered specialist nurse/technician training in Queensland, achieving multiple Veterinary Technician Specialist qualifications and inspiring a number of current team members to pursue this. During this time, the AEC was bought by Drs Rob Webster and Simon Lemin, and the successful business that is now the AES has partnered with VSS Underwood, Carrara and Jindalee.
