John Chan is just a simple layman, a cradle catholic who went through the stage of being indifferent and doubtful to being a convicted believer. He has no theological degree to boast about, but would on occasions share his faith as he had experienced and learned throughout his spiritual journey. He credits his conviction to Peter Kreeft, C.S. Lewis and Professor Emeritus Charles Rice, but mostly, to the prayers of his late maternal grandmother, the matriarch of the family's spiritual life.

John is a designated accountant working in the housing industry.
