Kevin Colleton - Managing Partner

I take the ‘roll up your sleeves’ approach with my clients to dive deep into how their business operates. It is all about knowing the right questions to ask to help solve real problems. Often what seems like the cause of the problem, is actually a result of another issue, which is why I keep researching until I find the real issue. When that happens, there’s a real excitement, because it means we can create the right solution specific to that client.

Joshua Jackson – Partner

  • BA Accounting

  • Member of Chartered Accountants Australia & New Zealand since 2013

  • Registered Tax Agent

  • Justice of the Peace

  • Partner at CBG Partners since 2017

I am the small and medium enterprise specialist in our CBG team, and I take great pride in fostering client relationships to help clients grow financially and to achieve their business goals. Everyone talks about scaling up, but what if we take the tools that create success for big business and down-scale them so that they also work for small business? You could say my speciality is in reverse engineering for success.
