The people behind the number.

Ken is a creative director and brand leader with deep experience of executing brand strategy across social, digital and paid media for blue chip businesses across the UK, US, EU, Asia and Australia.

Surprisingly, I started professional life as a chef but quickly escaped below stairs to become a graduate trainee in advertising. Trained by Ogilvy, I seemed to focus on building trusted relationships with international clients that start with the letter A: Avon, Air Canada, American Express, Autodesk, AT&T, Absolut and Amazon.com are some of the businesses that have taken me all over the world - living and working in Asia, Europe and USA. Having built agencies in these markets, I was asked to lead famous Brand and Design networks for WPP. I now split my time between Sweden and Spain, working as an Executive Coach using the Corestar platform and additionally hold three NED board positions.

I started preparing myself for today with an apprenticeship of more than three decades in brand strategy & comms, working on some of the world’s most iconic brands: American Express, Nestle, Guinness, Ford. In that time, I was a key architect of the Ogilvy Brand Stewardship Programme, later Harvard’s best-selling case study, and went on to help found the award-winning Ogilvy Africa network. I’ve taken on major leadership roles in the charity sector, including helping to unify the British Red Cross and chairing the UK Disasters Emergency Committee. I’ve also taken on the role as VP Business Development for Velti, a global marketing company installing and developing the first ever Click and Collect programme in the UK for Argos. So now I’m ready for all the pleasure and the pain of helping to launch a truly innovative & inspiring start-up. In parallel, I’m an active charity participant. As Deputy Chair of the British Red Cross had the role presenting at the National Presidents Conference why we had dissolved the 42 independently audited branches to create one unified society. Then as Chair of the UK DEC coping with the distribution of half a billion pounds of Tsunami donations followed by 11 separate disasters in the next 5 years. Currently Deputy Chair of a national addiction charity VIA and Chair of a local Healthcare Trust.

Most recently, Oonagh served as VP Brand EMEA at Goldman Sachs and NNIP before its acquisition, where she led significant repositioning work within one of the world’s most demanding corporate environments. Oonagh’s strength in change management is driven by an ability to retain an entrepreneurial instinct within corporate structures. Oonagh is creative, solution-driven and acutely aware that meaningful change rarely follows a straight line from A to B. She is excited to be able to use Corestar to help simplify some of those journeys.

I started out as an academic at St. Andrews, Sorbonne and the Open University. Then moved into the corporate world with over 20 years as global PR director for multinationals and became a published author with Penguin Random House. Now an award-winning coach and business strategist with a coaching style which is based on tough love, clear expression and an obsession with helping my clients find their true strengths. I have found a natural way to express this style in the Corestar methodology, which I helped to create. #Coaching #Flow-state #Courage #Confidence #Empathy #Motivation #Clarity

My career spans global creative agencies, start-ups and international development - from leading campaigns for Nike, Apple and Stella McCartney to shaping the Girl Effect in East Africa. I’ve built and led creative agencies, launched new ventures for Wieden+Kennedy and Warner Records, and guided organisations through change. Now, as a certified leadership coach (ACC), I combine that experience with leadership coaching and applied neuroscience to help creative & marketing leaders and teams reach their full potential, including using Corestar to diagnose issues which might otherwise go unrecognised.
