  • Ever since my first consult with Nathan 5 years ago I have been able to focus on the very reason I opened my small business, people. Nathan and Michael have both proven to me that they are in their business for the exact same reason, people. In a time where I have felt too often to count the times I have been treated just like a number it is refreshing to be treated as a person, thank you Griffin O’Dea Bowler.

  • I value Steve’s ability to rapidly establish my life goals and work with me to help achieve them. He considers all aspects including asset allocation, investment, insurance and tax planning.
  • Michael and the staff at Griffin O’Dea Bowler have been helping us with our financial affairs, including our taxation and our Family Trust matters for many years. Michael’s professionalism and the level of service have always been second to none. The staff return queries promptly and are always approachable and helpful. I heartily recommend Michael Ng and Griffin O’Dea Bowler.

  • Griffin O’Dea Bowler has been looking after my personal tax advice and the running of my family trust for over 6 years. I have found them to be very reliable in providing an excellent accounting service. Mr. Michael Ng is very professional, knowledgeable and practical in his job as our advisor. Michael and his team help me run my business effectively without consuming too much of my own energy in the accounting and financial side of my business.

  • Dealing with Michael Ng and his team has been a pleasure and a privilege. Michael has a great intellectual mind coupled with a caring attitude which makes him outstanding as an accountant and a person. He has high moral and ethical standards and comes highly recommended. Griffin O’Dea Bowler as a team cannot be faulted with their efficient handling of their clients and Andrew Phillis deserves a special mention as he is prompt in sorting out accountancy and those annoying enquiries regarding the Australian Tax Office in Michael’s absence.

  • I am grateful to Nathan for his natural ability to understand my business and bring my systems and structures to life. I trust he has my best interests at heart, knowing that to this accountant I am not just another number.
