A dynamic and results-driven Global Director of People, I bring a proven track record of scaling teams, shaping workplace culture, and driving strategic talent initiatives across various industries. Originally from Argentina, I’m fluent in English and Spanish, allowing me to navigate diverse, global teams with ease.

With experience spanning startups (~100 people) to enterprises (~7,000 people), I’ve worked in-house, at agencies, and as a consultant, giving me a unique perspective on talent acquisition, HR strategy, and people operations. I specialize in building high-performing teams, breaking hiring records, and fostering cultures where people thrive. Known for my strategic partnerships, succession planning, and performance management expertise, I balance agility with structure to help businesses scale without losing their core identity.

Passionate about creating workplaces where people feel valued and motivated, I bring a sharp eye for detail, strong decision-making skills, and the leadership necessary to influence and manage teams at all levels.
