  • Catalyst

As a leader in my 15 year banking career I ran a multi million pound P&L, weathered the Global Financial Crisis and led highly engaged teams.

As the Founder of leadership development company High Definition You, I have spent almost a decade working with executive leaders & teams on their resilience, emotional intelligence and high performance.

I am on a mission to liberate that 3 lbs of flesh inside your head from overthinking, so you can not just start seeing the possibilities but act on them with confidence and courage.

Female Inspirational Speaker and Chief Possiblist

I’m a coach, trainer, mentor, actress, former financial executive and neuroscience nerd dedicated to helping you to liberate yourself by seeing the possibilities.

My coaching programs have already helped tens of thousands of people, just like you, overcome the obstacles that are holding them back, and commit to a life they love. 

I bring three things from of my three different lives – the creative, the commercial and the cognitive. 

As a former actress, I bring creative thought and innovation to my programs, masterclasses and one to one coaching. 

Managing a multi-million pound PNL for a global investment bank  – I have a deep insight into the commercial challenges that people face in their corporate careers.

I’m also a neuroscience nerd. I’m trained in the neuroscience of decision making, trust, connection and change – which I bring to my work to support a deep understanding of the cognitive, the science behind your thought-processes

Why is being a Possiblistso important to you and your business?

Being a Possiblistgives you more; more extraordinary results, more high performance, more excellence, more sales, more engagement, more resilience, more confidence, more trust, more connection, more innovation, more accountability.

My love affair with human behaviour began at age 6 when I attended my first play. Who, I wondered, couldn’t be fascinated with the inner workings of the human being and how we portray ourselves and how we are perceived?! Understanding what makes humans tick and what forms ‘character’ developed over the decades from a fascination to an occupation.  An unexpected passion and study into applied neuroscience now informs my approach..

I continue to be dedicated to the inner working of people, and liberating them from the thoughts that are holding them back…

After leaving my 15-year banking career, a friend suggested that I would be incredibly effective as a leadership and communication skills trainer. 

With curiosity, I trained as an executive coach.

I also qualified in the Herrmann Brain Dominance Instrument, known as HBDI or Whole Brain® Thinking, a psychometric profiling tool which was a game-changer in terms of learning how our brains work. This helped me truly accept my new passion and trust myself as a qualified coach, ready to deliver real tangible value to those I work with. We still use this incredibly powerful tool in our leadership programs today!

Now almost a decade on, I have worked with countless people just like you, to undertake personal transformations and achieve their best possible outcomes.

Self-awareness and growth requires reflection. This isn’t easy if you don’t want to reflect upon who you are. You don’t want the thinking time, because all you do is have the same thoughts amplified in your head without any new information. For a large part of my life, I too was an over thinker.

It was a big shift to learn a different approach, and it didn’t happen quickly.

But YOU can accelerate that mindset shift rapidly when you’re equipped with curiosity and courage, you have commitment to the work and are willing for the community to support you and celebrate your success. 

You will need three things: curiosity, courage, and commitment.

To get from one side of the river to the other, you have to start with curiosity. 

You have to want to understand who you are. You have to have a curiosity about why the things that you want (on the other side of the river) are so important to you.

As a coach, I am ready to be the bridge for you. I will hold you through this process. I will help you realise that you have a community, not just with myself and the High Definition community I have built, but with those around you who can help you through the process. I can also help you see exactly who and what is holding you back.

We start with curiosity. My work with you is a catalyst for your transformation. 

You gain the courage to fail and be committed to working through things that may be more challenging for you so that together we can get to the other side. It is a process, but you’ll be able to recognise where you are and be empowered with self coaching techniques to work your way through and ultimately, celebrate your success!

Of course, once you get to the other side, this is not the end. There will always be more bridges to cross and milestones that you can and will achieve, through the same process. It will take consistency and commitment that will help you achieve your best possible outcomes, but the community that you choose to surround yourself with will help you remain focused.

We explore with curiosity, make conscious choices, accelerate courage, consistently commit, create community, expand compassion and pause to CELEBRATE! We call this sailing the 7 cs!

I’m here to help you. High Definition You was built to help you succeed.
