Chloe O’Sullivan


Hi there, I’m glad you’re here. Like you, I know from personal experience the importance of being able to relate well to others and how tough life can seem when there’s conflict at work and at home.

Once a senior banking professional, I experienced the personal cost of the fighting, blaming and justification that was routine in my place of work. I also witnessed the cost to the business of people being in conflict at work, with individuals, teams and sometimes even entire departments being at loggerheads with each other. It was the single biggest factor that created failure, inefficiency and absenteeism through stress.

When conflict is not handled well, and quickly, it escalates and can lead to employment tribunals, estrangement from loved ones, family break down, stress-related illnesses and worse.

I left the banking industry with a mission to uncover the root cause of all relationship difficulty. Through professional training as an executive and systems coach, I spent many years working with a team of people across several countries to create the award-winning War to Peace® methodology. Frequently described as life-changing, War to Peace® will not only enable you to effectively navigate conflict with anyone, it will provide you with mental clarity, inner resourcefulness, ease and enriched relationships in both your professional and personal life.

For more than a decade, I’ve shared War to Peace® with over 4,000 people from diverse cultural groups, all of whom have recommended it, including one of the negotiators who helped Nelson Mandela to end Apartheid. Now it’s your time to thrive and make relationship difficulty a thing of the past, so do get in touch with me, I’d be delighted to explore how I can help you or your organisation.

Wishing you my very best,

Chloe O’Sullivan BSc (Econ) Hons MBA

Why I created Halcyon Global

I wanted to make it as easy as possible for you to bring War to Peace® to your workplace.  With this in mind I have spent more than a decade bringing together and training a team of relationship and conflict resolution experts who are highly qualified to deliver the War to Peace® methodology.

What’s behind the name?

Halcyon, prounounced ‘hal-see-on’, is best known in the phrase ‘the halcyon days of youth’ and it tends to be used nostalgically, referring to the seemingly endless, carefree and sunny days of a joyful, happy childhood. The halcyon is, in fact, a mythical bird (often associated with the kingfisher) and originates from the Greek myth of Alcyone:

Alcyone was a Greek demi-goddess and wife of Ceyx. When Ceyx perished in a shipwreck, Alcyone threw herself into the sea in a fit of grief. Out of compassion, the gods changed them into halcyon birds. When Alcyone made her nest on the beach and waves threatened to destroy it, the gods restrained the winds and made the waves be calm during seven days in each year, so she could lay her eggs. These became known as the “halcyon days”, when storms never occur.

I want you to experience many more Halcyon days and fewer storms, so that you have the relationships you want  in both your professional and personal life.
