Let's Talk

Claire Callaghan-Cook

Leadership Coach

I’m Claire, a leadership coach, wellbeing specialist, and passionate advocate for better standards in health and social care. With over 25 years of experience in the sector, I’ve seen first hand the pressures faced by those leading teams in emotionally demanding and ever-changing settings. That’s why I founded Lumina: to support the people who support everyone else.

My work combines executive coaching, wellbeing support, leadership development and team training to help leaders grow in confidence, communicate more effectively, and build compassionate, high-performing teams. I bring warmth, tenacity and a deep understanding of what it takes to lead well – especially when resources are stretched, and expectations are high.

This work matters deeply to me because I’ve lived it. I’ve led teams, supported front-line staff, and navigated the real-life challenges of delivering care with compassion. I know strong leadership goes hand in hand with wellbeing – for individuals, teams and the wider culture. When leaders feel supported, energised and clear-headed, everyone benefits. That’s the impact I’m committed to creating through Lumina: Where Support meets Understanding.

What our clients say

Success Stories

The sessions have given me a lot of confidence in my role as a manager, and I now feel that I am doing okay. I have also learned that the overwhelming feelings I experience at times is due to my own personal development. Claire provided me with valuable advice on how to move forward, and I am actively applying all her suggestions. I believe this will help me become a better manager in the future.

Claire’s advice is invaluable and I wish I could have her in my life more, I already miss our sessions. I 100% recommend Claire, the difference in my role has been invaluable. Even if you think you’re doing okay, you will learn so much about yourself, and this knowledge can only help you improve.
