Slater & Gordon hopes the acquisition, which is expected to be completed by mid-August, will allow the firm to grow its personal injury market share in Queensland.

"Trilby Misso delivers growth that would have taken us a number of years and a heavy investment to achieve organically," said Slater & Gordon managing director Andrew Grech. "It also gives us a fantastic revenue base and highly skilled and experienced practitioners."

Trilby Misso's chief executive officer Graeme McFadyen welcomed the opportunity to be part of a larger team. "For clients and staff there will be no apparent difference after the merger is complete," he said. "But the benefit of being able to draw on the resources and expertise of Slater & Gordon is a very exciting prospect."

Trilby Misso employs 150 people across its five offices in south-east Queensland with over half of its practice in motor vehicle accident claims and 40 per cent in workers compensation. The firm will continue to operate as a stand alone business under the Trilby Misso name.
