Our Beginnings……
The company was started by John and Gwen Brennan in the late 1980’s and gradually grew into one of Western Australia’s most trusted and reliable investigation firms on the back of the hard work and dedication of its founders. Our company quickly earned a reputation for producing high quality, cost effective investigations for our clients, many of whom we still have strong relationships with today .
Mark joins the business…..
In 1996, John’s son Mark joined the business and under the guidance of John, he quickly developed into a senior factual investigator and leading figure in the business . The business continues to grow and develop new clientele.
Ady joins the team……
In 2004, Mark takes over the daily operations of the business. It was also around this time that Ady Claxton joined the organisation as a factual investigator and he quickly rose to the position of senior investigator, specialising in complex and psychological injury claims.
A new era……
Mark takes ownership of the business and implements a strategy that would see the company grow from a small team of 4 investigators to a team of 25 investigators, servicing a growing clientele. Under the management of Ady Claxton, the business starts up a new surveillance division which is a key step in the company moving forward and remaining competitive in a national market. The company also starts its public liability division with Senior Liability Adjuster Angela Anson joining the team.
Building on our strengths……
The company has continued to grow steadily, securing a number of major contracts with insurers including Allianz and QBE, providing a solid platform from which to build on moving forward.
Company Expanding
The company continued its growth by formally expanding into the General Insurance Investigations sector. Throughout ‘Covid 19’, the business remained focused on providing reliable professional service to our valued clients.
Paul Woodfield formally commenced in the role of Factual Investigations Manager in 2023 and became a director and part owner in late 2024. Paul was instrumental in researching and implementing a new company case file management system, which has streamlined our processes and provided significant benefits in terms of our cyber security environment.
After 8 years at our Rivervale offices, it was time to say goodbye….. and in August 2025 the business moves into our brand new office in Burswood.
