Nahuel Braihm

With more than 20 years of experience in human resources and finance, I am a passionate HR leader who believes in the power of people to drive organizational success. I have led HR teams and functions across various business units, industries, and regions through latam, supporting key leaders and managers in talent planning, performance, development, rewards, well-being, retention, and engagement. As the Head of HR at Essity Argentina, I was responsible for the full cycle of HR for over 300 employees, reporting to the South Latam HR Director and General Manager.

I implemented global HR processes and policies under Workday environment, defined a new sales force structure, and managed disruptive change in union and employee relations. Previously, as the HRBP and Employee Relations Manager for Southern Cone at Mars, I was a co-pilot in change management and organizational culture, leading regional and local projects in alignment with Mars' global standards.
