Seeds of Success

From practice to business

Sterling Harrison Law evolves from a founder-led practice into a collaborative, multi-adviser organisation as George hands over the leadership to Peter Nurcombe-Thorne. This ensures leadership continuity and guides the business into its next chapter as it transitions from a one-man band, to a team united in its philosophy.

2025

Leadership Continuity

Bernard takes over as CEO of the business, having been with RWG since 2012. This change further emphasises RWG’s broad leadership base and the firm’s long-term commitment to serving clients across generations. Having previously served as COO, Bernard has been deeply involved in the firm’s ongoing evolution — making for a seamless leadership transition.

TODAY

Sustainable Growth, Global Reach

Sterling Harrison Law now employs 20 individuals and manages a diverse, global client base. The business continues to evolve while holding fast to its values—offering independent, carefully considered advice rooted in genuine care for each client.

TOMORROW

Clients First. Always.
