Non-violent Communication and Servant Leadership are pivotal concepts in peace education. While their roles in fostering peace within conflict and post-conflict societies have been explored, their effects on professional practice remain under-researched. The notion of peace encompasses not only global and societal dimensions but also inner peace and interpersonal relationships, where the actions of diverse professionals significantly contribute to peace-building. Cultivating a synergy between non-violent communication and servant leadership is essential for professionals to lead with empathy, respect, and care for others within their communities. This qualitative and interpretative study investigates the synergy between non-violent communication and servant leadership and its impact on professional practice. Using Participatory Action Research, this study involved a Six Week Certificate Course in Non-violent Communication and Servant Leadership offered by Global Peace Let’s Talk, United Kingdom. The research includes a thematic analysis of reflective submissions from participants representing different countries around the globe, providing empirical evidence of the benefits of this synergy for diverse professionals. Examples analyzed are from fields such as education and training, law enforcement, social work, and journalism.
