Jon is the founder of Global Alliance Advisory Services (“GAAS”), the leadership support consultancy
uniquely dedicated to serve international accounting networks and associations. The GAAS team
comprises former CEOs and Executives based in the UK, Mainland Europe, and the USA.
GAAS focuses on the development and implementation of growth strategies, facilitating merger
opportunities and assisting across the broadest range of operational issues for central offices. For
networks, GAAS offers an outsourced global quality management, monitoring and inspection service.
Managing global independence reporting effectively is a major issue for the networks and GAAS was
instrumental in the development of the Zenzero Global Alliance Hub which utilises the Microsoft
Power Platform and Microsoft 365 to deliver a cost effective cloud-based solution to fully automate
the process. The module can also be applied to gather and collate information from the global
membership such as the IAB survey requirements.

Jon is best known from his days as CEO of Kreston International which he led for 13 years until 2019
having previously been Managing Partner of a 9 office UK practice. During his long career in the
profession, Jon has managed accounting practices at every level – regional, national, and global.
