The Most Progressive, Results Driven,
Business Coaching Firm

When David Guest first started up this coaching firm 15 years ago, he had a vision to transform the lives of thousands of business owners across the country; starting with his local community.

What he discovered in the marketplace was very different to what he was expecting…

When David Guest started his firm 15 years ago, business coaching was a very new field and there were all sorts of different people in the industry… it was un-regulated and still is.

David grew up in a family business and started working from the age of 5. He watched his parents MAKE a lot of money and LOSE a lot of money and wanted to know why.

He started looking for business opportunities himself… and he failed… a lot. It wasn’t all a loss though as it lead him on a journey of discovery – Now before you go all Zen on us, and start re-arranging the furniture, it was simpler than that.

He started reading books… as many as he could get his hands on. From psychology to sales, and it was hundreds of books down that he realised there was a formula.

Business isn’t about knowing everything, it’s about learning. It’s about evolution and innovation and being creative with the skills and knowledge that you have. With this, he has become one of the most successful business coaches in Australia and leads a team that continues to change the lives of business owners every day

Why do we do it?

When I watch a business owner who has been in business 5 – 10 years and they are doing ok – they are making money but they are working hard… and watching the look on their face when all of a sudden money starts coming in to the bank account, or they can book that holiday they have been trying to book for the past 5 to 10 years, or they can go and spend more time with their family… those sorts of things are really what drives me to get up in the morning

Meet The Team...

David Guest

Director/Head Coach

I am a perpetual learner. I discovered from a young age that “the more you learn the more you earn” and I have been actively educating myself ever since (over 30 years). I have been coaching businesses for 15 years; prior to that I was in sales and marketing for 10 years.

When I’m not in the office, I like to mix it up – spending time with family and friends is a must, but I also love to go out into the elements. From Kite surfing and skiing, to motorbike riding and car racing (and YES, I built my own Elfin), If there is fun to be had, you’ll find me there.

My favorite part of what we do is seeing the look on the business owners face when they start making more money than they had ever anticipated. That’s why I do it. There is nothing quite like it.

Annette Guest

Admin & Office Manager

I keep the office together. My role is a hybrid of Office Manager, Administrator & Client Relations… I am also the Chief Cocktail Maker in the Office (A Very Important Role)

Outside of work, I love to spend time at the beach and catching up with family and friends.

Being a bit of a foodie.. Dinners out accompanied by an exotic cocktail spells perfection for me.

What I love the best about what we do is when I hear the amazing stories of all the successes our clients have. I believe passionately about what we teach and this is confirmed to me everyday when I see the smile on people’s faces after they finish a session.
