About me

Welcome. I’m Sonia Thomas, an executive and team coach with over 30 years of international experience.

Originally from Northern Ireland and now based in Paris, I bring a global and intercultural perspective to my work, shaped by a long career in international leadership, alongside my coaching practice.

I have been coaching leaders and teams since 2019. Prior to becoming fully independent in 2021, I served as Chief Operating Officer of UFI, the Global Association of the Exhibition Industry. In this executive role, I worked closely with senior leaders, boards and international teams, navigating complex organisational, cultural and strategic challenges at a global level.

Today, I accompany leaders and organisations who want to strengthen their leadership posture, build confidence and navigate change with clarity, perspective and resilience. My approach is grounded in real executive experience and combines pragmatism, reflection and a strong intercultural and systemic lens.

I hold a University Diploma from the University of Paris Dauphine-PSL (top of the cohort; 300 hours of learning and a dissertation) and am certified by the Cabinet Chrysippe, Lyon. I also hold a certification in Inclusive Leadership through Behavioural Studies from the London School of Economics.

Alongside my private practice, I teach HR Management at Université Paris Dauphine-PSL and coach teams within the Executive Master in Innovation & Entrepreneurship at HEC Paris. I also advise international organisations and associations on leadership, inclusion and organisational transformation.

Why Choose Me?

  • International Experience
    With over 30 years of international experience across sectors and leadership roles, I bring a global perspective to every coaching engagement. My work has taken me from Northern Ireland to Paris and beyond, helping clients navigate complexity in multicultural environments.

  • Cultural Insight
    Having lived and worked across borders, I understand how culture shapes communication, confidence, and collaboration. My coaching integrates this awareness to help you work more effectively in diverse and international contexts.
  • Tailored Coaching
    No two coaching journeys are the same. Each programme is designed around your goals, context, and rhythm — ensuring that every session is practical, relevant, and sustainable over time.

  • Trusted Practice
    My approach is grounded in ethics, confidentiality, and measurable impact. I’ve helped leaders and teams strengthen confidence, presence, and cohesion in times of change, always in a space of trust and discretion.
