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.

The coaching experience enabled me to recognise things I needed to change in my work life, so I had a better work and home life balance. I now understand my leadership style and have started to change those things I wanted to change, including staff in decisions and building our vision for our service. 1 100% recommend Claire, she helped me focus on what I wanted and what I needed to change and I am now in a much better place both at work and at home. Thank you so much Claire, I will never forget this programme.

Working with Claire has been a transformative experience. Her ability to create a safe, supportive, and thought-provoking space has helped me unlock new perspectives, challenge limiting beliefs, and grow both personally and professionally. Through our sessions, I’ve gained clarity, confidence, and a renewed sense of purpose in my leadership.

What sets Claire apart is her deep empathy, insightful questioning, and unwavering commitment to helping me become the best version of myself.

Since JM began this programme, I have seen a huge change in her mindset. She is a more critical thinker and a positive influence on others. She reviews things from both sides and understands the wider demands of the organisation. She is a more diplomatic leader and challenging direct report. I would recommend this to anyone. JM has had nothing but positive things to say about Claire and her overall experience. Claire has been helpful in keeping me updated with progress where it was needed and it has meant for us that we can keep and develop our home-grown talent.
