The practice at 69 Grantham Street began in 1923, over a century ago.
It was run by solo GPs, Dr. Davies for 33 years, followed by Dr. Tom Walshe for 23 years. The premises served as both a clinic and a residence for the doctors and their families.
In 1991, Dr. John Stanton acquired it, relocating his practice from Nicholson Street, Carlton, where he worked with Dr. Joanna Flynn, who also moved to GSGP. After many years at the practice, Drs. Li-Hsia Neoh and Debra Wilson joined Dr. John Stanton as practice principals in 2016.
In 2021, they became joint principals when John Stanton stopped managing the practice and retired in August 2022 after 31 years.
