Here's what our clients say about us......
David - Managing Director at 3D Live Pty Ltd

Like the old saying your business is only as good as your accountant... we are lucky we came across Mike as our accountant. He has been instrumental in the success of our start up business. His advice is always on the money. He spells out the pro's and con's of any given situation and lets you make an easy, informed decision of what action to take. He is a personable, down to earth bloke. I can't recommend his services high enough.

Mike is a great Accountant to deal with.
He knows his stuff and always goes out of his way to accommodate early or late appointments.
I would highly recommend him to anyone looking for an Accountant.

Jeff - Talent Acquisition Specialist - Schneider Electric

I have been using Mike for a couple of years now after a friend recommended him when I lived in Sydney. When we relocated to Brisbane I wanted to keep Mike as my accountant because of the trust I have in him and his staff. Mike has really helped me with clearly defining the options available to my wife and me with regards to a family partnership consultancy we operate. Mike is extremely skilled and diligent in what he does successfully reducing my liabilities. Mike also liaised directly with my mortgage broker to provide relevant paperwork to secure a mortgage. Mike is extremely patient spending extensive time to understand his client’s needs responding very quickly when my submissions are potentially running late! I have also found that whenever I call his office the staffs are friendly and effective. I very highly recommend him.less
