‘When I first met Ella over ten years ago, she was a curious and enthusiastic learning and development manager at an international bank based here in Sydney. Even then it was obvious she would be a coach as she was both intrigued and passionate about the human condition and understanding how best to support people to shift their results. Since those early days I’ve followed Ella’s journey as she has transitioned from corporate executive into building a successful coaching practice with clients across the globe. I’m very excited that she has finally put pen to paper and started unfurling some of the many ideas and coaching concepts she has been developing. Ella’s approach to coaching is unique and I love how she explores different perspectives in her book, especially the concept of the different “operating systems” we have. She has much more to share and I’m already looking forward to the next instalment!’

‘Upgrade is a complete step-by-step guide to renewing your whole being and will help you reach your full potential in life and work. It is filled with anecdotes, research and quotations from thought leaders around the world. I highly recommend it.’

‘Ella has written a delightfully readable book that shares honest and real-world insights about what we all need to do to thrive in the complex and competitive world we now live in. Ella shares hard-earned personal lessons, examples from people who “upgraded” their operating systems, with simple but powerful tactics, in a direct, friendly, and at times humorous way. We need to face some harsh truths if we’re to thrive because our four operating systems drive how we show Testimonials ix up in the world. Jump into this book if you want to become a better, healthier, calmer and nicer leader – and human! It deserves to be read by everyone who is feeling overwhelmed, stressed and suffering from “infobesity”! Thank you, Ella, for sharing your unique and refreshing wisdom with us!’
