Terry Zimsen: A Visionary Leader Transforming Business Success in Australia
In 2001, after holding senior roles and being a partner at one of the country’s leading CPA firms, Terry Zimsen launched his own practice to create a firm built on partnership, mentorship, and lasting client relationships. From humble beginnings, Zimsen Partners has grown into a dynamic firm with over 40 professionals, shaped by Terry’s vision of combining technical excellence with a strong service culture.
