The Personal Piece

Why have I dedicated my life to helping you discover and contribute your unique value?
After defying death twice, the way I saw everything – from life and business, to people and perspectives – changed. Give me odds and I’ll show you how to defy them. Show me challenges and I’ll reveal how to transform them. Tell me about your lived experience and I’ll help you use the gold therein as part of your work. Describe the next level in your business and I’ll show you all that it can become.
What is this work all about for me?
I believe in our individual and collective potential and work to shape and support business that moves the world forward into that place of possibility. Working one-to-one is my greatest joy, as we bring forth the best in your potential, clarity, confidence and self-expression.
How do I know what it is to connect with, appreciate and communicate your unique value as a thought leader?
For over two decades, I’ve been supporting hundreds of emerging and established thought leaders, from the globally renowned to those with fascinating new ideas to share. I got here when life-threatening illness struck at age twenty-six and removed me from the financial career and life that I knew at the heart of North America’s financial sector. The universe was clearly redirecting my path. The subtle whisper I had long heard to pursue “something more” had turned into a blunt redirection. It was to a new path of supporting fascinating leaders. I never looked back.
“Life has no meaning. Each of us has meaning and we bring it to life. It is a waste to be asking the question when you are the answer.” - Joseph Campbell
In the throws of debilitating illness, I journeyed through introspection and questions about purpose, human behavior, psychology and spirituality. Through the process of my healing, I came to see the forest for the trees in all aspects of life – the interconnectedness of all things big and small, in any circumstance.
Today, I use that same ability to strategically hone and brilliantly articulate all facets of your thought leadership business – from the big-picture brand and business vision, to the intricacies of how specific positioning and wording will land with your audience. All this while bringing to the table a host of profound knowledge about business, psychology, finance, personal growth, wellbeing, health and mindset.
My clients are status quo shifters – thought leaders, founders and CEOs aiming to redefine the way we live or do business. They believe in merging business, psychology and spirituality in order to maximize impact and their own contribution. To develop unshakable belief in your revolutionary vision or incredible personal story, and create a world-class brand, I hope you join me for a life-changing exploration and dissemination of your ultimate thought leadership.
