Nathan Campbell
Nathan runs St Eutychus. He loves Jesus. His wife. His daughter. His son. His other daughter. His dog. Coffee. And the Internet. He is the campus pastor at Creek Road South Bank, a graduate of Queensland Theological College (M. Div) and the Queensland University of Technology (B. Journ). He spent a significant portion of his pre-ministry-as-a-full-time-job life working in Public Relations, and now loves promoting Jesus in Brisbane and online. He can't believe how great it is that people pay him to talk and think about Jesus.
