Owning a business is NOT about working yourself into the ground for the sake of trying to squeeze out a living. It is NOT about making tons of money at the expense of losing tons of life. It IS about maximizing life, bettering your life and the lives of others, which, not so ironically, fattens your purse."

Mike Michalowicz, Author of Profit First and The Toilet Paper Entrepreneur

I am an entrepreneur and the Principal of McDermott Business Strategy & Coaching. I have built a successful international coaching firm from scratch and co-founded two other businesses.


Whether you’re looking to start a new business or to continue to grow an established one, my business coaching will help you get clear on what kind of business you want to run, develop a strategic plan that matches your vision, and implement the plan with ongoing accountability to ensure your dreams become real projects with results you can measure.  


I work with both small and large organisations. I take a service-based approach that places the customer at the centre of all business design work, ensuring your business flourishes and is a pleasure to run.


My approach includes cutting-edge marketing and sales strategies, a focus on delighting the customer beyond industry standard, understanding how to nurture your team so they perform at an optimum and want to stay in your business for the long-term, and implementing sound money management systems.  

There is no perfect recipe for being a good leader and manager, which is why I tailor my approach to each business I work with, based on their unique context and team.


After a business coaching journey with us, you will:

  • Know how to set goals that stretch your team but are also achievable; 

  • Have influence as a leader and understand how to be an inspirational manager;

  • Be able to present with impact and clarity to your Board, your Executive Leadership Team, and the team/s you lead; 

  • Be incredibly clear about your strategic objective (why your business exists!) and the pathway to achieve your strategy; 

  • Create performance management conversations that genuinely develop your people;

  • Be confident in your ability to build and maintain a truly successful business;

  • Increase your profit by addressing the systems of your business that are not running at optimum, and revealing the areas that contain unrealised potential;

  • Get clear on the best business model that suits your business, and redesign your current model as needed; 

  • Have learnt swift and effective innovation strategies to run your business more smoothly;

  • Develop stronger business leadership and interpersonal skills; and

  • Create a work life balance that you really enjoy, that pays you well, and that provides you with the freedom to enjoy a high quality lifestyle.

I help you successfully address your business challenges by walking alongside you in a private coaching relationship that is personalised to your business. I get to know you and your business deeply using my proven business coaching tools and methodologies.


With some businesses, I dive deeper and coach and consult to other leaders in your business if that is required to achieve your strategic objectives. This can be in both a one-to-one and/or group format depending on context. 

My clients have included Nespresso, Visionstream, Charter Hall, Emerald Coaches, Key Commerce, Salmat, Port Waratah, The Port Of Newcastle, The NSW Department Of Communities & Justice, and The NSW Department Of Transport.

“David worked with me to provide some business coaching for my consultancy which was hugely valuable. He really helped me to separate issues into distinct buckets and then helped me to identify the core problems that needed addressing under each business category.”
