I grew up within the accounting firm culture as my father and grandfather were accountants. Following in their footsteps, I joined our family business in 2013, after qualifying as a CA(SA) in 2009. During my time at the family business, I developed a passion for proactive tax planning, and making use of trusts and proper estate planning to protect family wealth. In 2017 I decided to broaden my tax knowledge and skills. I completed a postgraduate diploma in Tax Law at the US in 2019. 

I enjoy applying these respective disciplines to suit family-owned farms and businesses. Apart from being a passionate businessman, I am also a dedicated husband to my wife and father of three beautiful children.

After qualifying as a lawyer, specialising in Tax and Business Law, I moved into banking. With more than 25 years of experience in various senior and executive leadership positions across multiple market segments, my focus in recent years shifted towards tax disputes and the legal aspects of a business strategy. With a comprehensive knowledge of the dynamics of business, I specialise in taxation and dispute resolution - assisting business owners to navigate complex tax law.  

Having worked with business owners, I have seen the successes and the failures. Resolving complex tax issues and building personal client relationships are key to keeping me enthusiastic about our enterprise. 

Outside of the office, I am a family man who enjoys the outdoors and loves animals.

After obtaining my Professional Accountant (SA) designation, I decided to specialise in taxation and business / trust advisory. My postgraduate diploma in tax law has also aided in my ability to provide sound and meaningful advice. I mainly specialise in taxation and truly enjoy being able to assist clients efficiently and effectively by helping them manage their tax affairs and resolving tax disputes. 

My enthusiasm for problem solving and dispute resolution truly has turned my career choice into a passion, and I look forward to being able to continue building meaningful relationships with existing and future clients.
