Over that period he led Thomsons through four distinct phases of growth, from a small regional practice, to a respected mid-tier national firm, to a preeminent challenger brand, and now to a major firm operating at top tier level across a growing number of practice areas with greater ambitions.

Under his leadership, Thomsons has risen to represent private and public sector institutions across every mainland State in the country on their most challenging assignments.  Equally important to Adrian has been the development of a firm identity and culture defined by social equity and competitiveness.
