Creative thinkers and opportunity spotters

Adam Dierselhuis

Adam Dierselhuis

Director

Adam grew up working in his family’s service station – the old style station where you got fuel in the tank, your windscreen washed and your tyres checked all while you were sitting in your car. It was here that he found his passion for business, and just like any other business owner / operator, his dislike of tax.

That passion and energy for helping business owners create better businesses and minimising the amount of tax they pay resulted in Adam’s decision to study a Bachelor of Business at university and pursue a career as a Chartered Accountant. Adam has a talent for spotting opportunities and enjoys challenging the status quo to get the best results for his clients.

Adam has had the enriching experience of being the Queensland Regional Council Chair for the Institute of Chartered Accountants (now Chartered Accountants – Australia & New Zealand), leading the council in a series of regional tours around Queensland and driving actions on behalf of members. Adam is passionate about giving back to the community in endeavours such as this, as well as presenting back to lectures in universities and being involved in The Executive Connection (TEC) and other business forums.
