Sean’s key interest is advising families of substantial wealth on the role of the family office in achieving family harmony and wealth preservation across the generations.

Sean has worked with a number of prominent families, locally and overseas, on matters of family governance and structures, including the design and implementation of family office infrastructure. He is a recognized thought leader in the family office arena and regularly writes and presents on topics that are challenging for families.

Sean has been an active volunteer in the philanthropic sector for many years, having co-founded the Chapman Eastway Charitable Foundation and serving as Chair of Epilepsy Action Australia from 2016 to 2018.

Sean is a fellow of the Institute of Chartered Accountants in Australia and New Zealand, a Chartered Tax Advisor and has received TEP designation from the Society of Tax and Estate Practitioners for his experience as a tax and estate practitioner. He has a Bachelor of Commerce in Accounting from The University of New South Wales and has also been awarded a certificate in Fiduciary Governance from the Thunderbird School of Global Management.
