Mark Kentwell



Mark knows accolades aren’t everything; but being named Principal of the Year in the 2020 Australian Real Estate Business awards sure would be to most.

Pulling engineering, trades, events and band management, Mark (or Kenny K as some call him in music circles) is able to create a system that has the consumer at the centre and optimisation top of mind. Not just a thought leader, but a coach to those around him, he uses calculated strategy and a wealth of experience to help others play better, and win. Here to develop a dynasty, Mark’s mission for Henderson can be summed up in one word: growth. Game on.

Mark knows: quality over quantity pays, which is why his favourite drink is an Old Pulteney 21 Year Whisky. And that’s exactly what Henderson Advocacy delivers: a top-shelf kind of service. Because your standards are high, and we only serve premium.
