David Longfield

Managing Director

I started Longueville Media because I was passionate about helping to write and publish books that made a difference to people's lives. 

After completing a literature degree, I secured a wonderful start for a publishing career with a position at Oxford University Press, first in Sydney, then in Melbourne as academic marketing manager. That was 26 years ago. I built on this experience as academic commissioning editor, developing new books for the undergraduate and postgraduate law market at ThomsonReuters.

It was time for a different perspective, so I moved to managing corporate magazines for organisations such as The National Trust, Clayton Utz Lawyers, Fujitsu, and Microsoft, in the custom publishing division of Text Media.

I had always wanted to start my own business, so in 2002 I took the step. I love the variety publishing offers. It’s always fantastic getting to know a new subject area when helping authors create their books. Today I always try to spend time all our clients to help in manuscript development and some ghostwriting.
