Manuel Guerreiro

Professional Certified Coach & Organizational Psychologist

With 20+ years across global multinationals → Liberty Mutual → Barclays Bank → Philip Morris International → Arrow Global,— I have lived the full organizational lifecycle, from rapid expansion to significant workforce reductions. I led teams from the age of 23, served as HR Director at Whitestar Asset Solutions and Norfin, and later led the Human Resources and Communications areas for Arrow Global in Southern Europe, overseeing eight companies across Italy, Portugal and Albania, before becoming Group People Experience Director responsible for the Group’s overall people and organizational development strategy. Earlier, I was HR Director at Philip Morris International in Romania and Head of HR at Tabaqueira’s manufacturing site in Portugal, having also worked at Barclays Bank in Spain and Portugal and started my career at Liberty Mutual.I navigated radical transitions — from banking to factory environments, from long‑standing traditions to agile, transformation‑driven cultures — and international assignments immersed me in diverse cultures, languages, people, traditions and work styles, expanding my cultural literacy, global network and strategic perspective.

As a long‑standing member of executive committees, I developed deep empathy for the realities, challenges and responsibilities of leaders — an insider perspective that only lived experience at the highest levels of management can provide.
As an HR professional, I learned that I could create profound positive impact by making employee wellbeing and happiness a daily professional priority, and that is what has truly fueled my motivation.

My work focuses primarily on themes such as chronic stress, burnout, professional identity, decision-making, emotional regulation, and the balance between performance and well-being.
