Principal Consultant Latin America

Leadership Stems from Practical Experience, Not Merely a Title

My leadership journey is anchored in practical experience, producing tangible outcomes and helping organizations transform insights into actionable strategies and business growth. Over the course of more than forty years working in leadership, organizational development, and entrepreneurship, I’ve held roles across multiple industries—from becoming one of Chile’s pioneering female Civil Engineers specializing in chemical processes, to establishing consultancies and advising companies entering the Chilean market. My entrepreneurial efforts include engineering consultancies, outsourcing firms, and agencies in Chile and Peru that supported prominent American retailers such as Walmart, JCPenney, and Nike.

Fifteen years ago, I founded Business Evolution Strategies (BESTART), a boutique consultancy that helps women entrepreneurs and executives turn human-centered leadership into a competitive advantage – strengthening their businesses, expanding their influence, and becoming the exceptional leaders their next stage of growth demands. 

Leadership Philosophy

Sustained performance relies on clear standards, Conversational Intelligence®, and emotional intelligence in everyday routines. This approach enables leaders to build clarity, trust, purpose, optimism, and accountability for consistent growth. Success depends on meaningful engagement and supporting others. Building trust through empathy, open dialogue, and thoughtful guidance create environments where individuals feel valued and motivated to achieve measurable outcomes.
