My Story


I still remember standing in the CEO’s glass office, heart racing as he asked, “Why invest in sustainability—and what will it cost us?” In that moment, I knew I had to speak their language: clear business value.
So I flipped the script. Instead of charts, I showed how a system-wide sustainability strategy could cut costs, boost efficiency, and open new markets — while slashing 30% off a client’s emissions and saving millions. Suddenly, corporate sustainability wasn’t just “nice to have”—it was a clear profit driver.
From Spain to Sweden to the Netherlands
Born in Spain, I honed my skills in Sweden at a top university for system transformation and sustainability strategy. Now, as a Sustainability Consultant in the Netherlands, I lead rapid decarbonization sprints: mapping complex systems on digital whiteboards, pinpointing high-impact moves, and turning data into simple, action-ready roadmaps.
Mentoring the Next Generation of Green Leaders
Today, I bring that same friendly, hands-on approach to sustainability career mentoring — guiding professionals into finding their path in the industry.
