"I run an industry association in a fast changing environment, and needed help with board evolution and my own role as Company Secretary. I was fortunate to have been acquainted with Quentin as he was starting Vanguard and he has been a trusted advisor to me for several years now. He is flexible to fill the gaps as required and then rigorous and precise in his delivery. I would highly recommend Quentin to anyone seeking governance advice, company secretariat support, or simply a reliable expert for second opinions. I have already recommended him to others who have benefited from his expertise, and they have, in turn, recommended Quentin’s support to their contacts, so get into his books if you can. Quentin is the most reliable partner for your business that you could find."
