Rev. C. P. Schwieger, known as Percy, was vicar at Holy Trinity from October 1934 to 1953. Many Children in Surrey Hills were baptised by him as there was a population explosion following WW2. There is a stained glass window of Mary and Martha with Jesus that he donated to the church in memory of his wife Mary, obit. 6.4.1949. He oversaw many improvements to the church properties over the time when the parish was extending to St Augustine in Balwyn and land was obtained for the church at Wattle Park, now closed.
