Over the past year, my professional relationship with Guillaume Oberholster has proven to be one of the most valuable investments I have made in my roles as a business owner, practising attorney, founder, chairperson, and CEO. Guillaume’s patience stands out as a defining quality, and it is a business value from which I continue to learn and benefit.”
Coaching and Advisory Impact
What has been most remarkable, from my direct experience, is Guillaume’s exceptional skill in coaching and collaborating with executives and teams, regardless of their stage of development. In his capacity as an advisor to Donnelly-Bornman Law Inc. and as our fractional CFO, he has consistently delivered tangible value to our organisation. Thanks to his experienced guidance and foresight, we have advanced swiftly as a business and law firm, reaching our goals and targets, and making progress at twice the speed we previously achieved.
Professionalism and Character
Despite a wealth of experience and a history of achievement—as a partner of one of the most well-known and recognised nationwide accounting practices, a senior chartered accountant, business owner, CEO, and international advisor and investor—Guillaume remains grounded and purposeful. Years of playing tennis have shaped his core philosophy, evident in his commitment, agility, patience, foresight, humility, discipline, perception, focus, and health. He knows when to step back to recharge and return with renewed dedication. Guillaume teaches the same principles in his approach to others’ success.

I just want to take a moment and thank you for all that you have done for me.
I started TAB out of curiosity to see what it was about. Wow, I was in for a treat. This was not your average business coaching. TAB is so easily interchangeable with your personal life and I found that the more I worked on one, so the other side of my life would improve too. What really impressed me about TAB was that it was so simple, easy to navigate and easy to see at a glance and get a global picture of where I was going, what needed work and I could update it without any effort.
I loved the board meetings and getting to see other business owners who have similar struggles or be stimulated by new and interesting challenges. I formed long lasting friendships and was really challenged to think out of the box when discussing business challenges.
Guillaume, your constant support, checking in on me and making sure I was coping was so appreciated and valued. Through the TAB system and your compassionate counselling and guidance I feel that Snappy and I both benefited in may ways. I have grown and feel so much more in control of my destiny thanks to TAB. I would encourage any business owner to do TAB for at least a year and have their life changed.

I am pleased to write this testimonial for Mr Guillaume Oberholster, with whom I also have had the pleasure of working for three years as a co-trustee of Tredenham Valley Estate Body Corporate. As a chairman of the body corporate, he consistently demonstrates exceptional qualities, e.g. leadership, creativity, etc.
One of his most notable achievements was turning around the financial position of the estate from being in the red to having surplus. His accounting experience contributed to this success.
He is a studious person of fine character and the highest integrity.
Mr Oberholster is a joy to work with and a team player and always brings a positive attitude. In his new career (TAB), he mentors business owners, and I personally found his guidance relevant and practical.
I wholeheartedly recommend him for any opportunity that comes his way.
