About Us

David Longfield

Founder & Managing Director

David began his publishing career at Oxford University Press. He went on to commission academic and professional texts at Thomson Reuters — then known as The Law Book Company — developing titles for the undergraduate and postgraduate law market. He then applied that editorial discipline to corporate publishing, managing magazines and content programmes for organisations including Microsoft, Fujitsu, the National Trust, and Clayton Utz.

In 2002, he founded Longueville Media. In the years since, he has worked with federal and state governments, universities, major corporations, cultural institutions and private authors to produce publications that have won international recognition and, more importantly, that his clients are proud of.

He is still closely involved in the editorial and strategic development of every Longueville project and cares about the outcome. Clients who come to Longueville Media are working directly with the person who has been doing this for nearly twenty-five years.

Siobhan Gallagher

Senior editor

Siobhan brings an unusual combination of precision and range to her editing. Her background spans science and corporate finance — disciplines that demand accuracy, rigour and the ability to follow a complex argument — and she has applied that discipline to editorial work for more almost twenty years.

She edits across Australian, UK and US conventions and has worked on publications ranging from government histories and commemorative books to expert-led non-fiction and academic research. Her attention to detail is matched by her sensitivity to voice: she improves manuscripts without erasing what is distinctive about how the author writes.
