Guillermo’s Story: Lessons from Patients’ Lives 

In the pharmaceutical industry, it’s easy to focus on data, strategy, and performance metrics. But behind every decision are real people. For Guillermo Castillo Acero, Head of European Mid-Sized Markets at Ipsen, that reality became clear during a precise moment in his career.

Early on, Guillermo describes his role as driven largely by delivering results. That changed during an awareness campaign on spasticity, organized in partnership with a patient association. The initiative, a race designed to raise visibility and promote inclusion, brought together patients, families, and healthcare stakeholders around a shared cause. 

During a disease awareness event, Guillermo had the chance to speak directly with families. He expected conversations about treatments or clinical outcomes. Instead, what he heard was far more personal. They spoke about everyday challenges, getting dressed, eating, managing routine tasks, things often overlooked but deeply impactful for people living with spasticity. 

The experience was emotional. Guillermo recalls struggling to hold back tears as he watched families connect, share, and find joy simply in being part of a supportive community. That moment stayed with him and reshaped how he viewed his work, not as a business responsibility, but as something that directly affects lives, both for patients and those around them. 

Since then, Guillermo approaches his role with a stronger sense of purpose. The work is no longer just about outcomes on paper, it’s about enabling better daily lives. Sometimes, it only takes one moment to change how we see what we do. For Guillermo, it was listening, truly listening, to patients and their families, and realizing the human impact behind every decision.
