Hi, I’m Chloe O’Sullivan, a Conflict and Relationship Specialist. If you’ve ever felt stuck in difficult interactions – at work, at home, or even within yourself – you’re not alone. Conflict can feel exhausting, but it doesn’t have to be that way. I know how draining it can be when the same tensions keep resurfacing, no matter how much you try to resolve them.
Why Work with a Conflict and Relationship Specialist?
I help people who want to become truly skilled at handling conflict – not just managing it, but transforming the way they experience it.
When you have the ability to navigate conflict resourcefully, you don’t just cope – you stay clear-minded, responsive, and in control, even in the most difficult interactions. Without this, stress takes over, time is wasted in frustration or overthinking, and conversations spiral into defensiveness, avoidance, or regret.
The people I work with become exceptional at handling difficult people and situations by learning – and practising – the award-winning War to Peace® methodology.
War to Peace® has been experienced and recommended by every single participant worldwide since 2009 – including one of the negotiators who worked with Nelson Mandela to end Apartheid.
Once you experience this approach, you’ll finally understand why certain relationships feel so challenging – and more importantly, you’ll know exactly what to do about it. You’ll stop wasting energy on the same frustrations and instead feel confident and equipped to navigate even the most difficult situations with clarity and ease.
If you’re ready to handle conflict differently and free yourself from the stress of difficult relationships, I’d love to hear from you.
Wishing you my very best,
Chloe O’Sullivan BSc (Econ) Hons, MBA, PCC
Creator of War to Peace® and CEO of Halcyon Global
Why I Created Halcyon Global
I founded Halcyon Global with a vision: to make this work accessible to as many people as possible, far beyond my lifetime. War to Peace® has transformed thousands of lives, and I want its impact to continue long after me—helping people break free from the stress of difficult relationships and navigate conflict with clarity, confidence, and ease.
For over a decade, I’ve been building and training a team of exceptional experts—people who are not only highly qualified but deeply committed to delivering this work in a way that makes a lasting difference.
Because no one should have to stay stuck in conflict.
What’s Behind the Name?
You may have heard the phrase “the halcyon days of youth”—a nostalgic reference to a time of peace, joy, and ease. But Halcyon has deeper origins in Greek mythology:
Alcyone, a demi-goddess, was devastated when her husband, Ceyx, perished in a shipwreck. In her grief, she threw herself into the sea—but the gods, moved by her sorrow, transformed them both into halcyon birds. Each year, they calmed the winds and stilled the waves for seven days so she could safely nest—giving rise to the “halcyon days”, a time of calm in the midst of life’s storms.
That’s exactly what we want for you.
More halcyon days. Fewer storms.
Stronger, easier, more fulfilling relationships—at work, at home, and within yourself.
