As an avid fan of comics and art history, I find great joy in using my imagination to explore fantastical worlds and delving into their historical context. I am equally captivated by the rich and varied cultural traditions of language, food, religion, and ways of life, as they offer an authentic glimpse into the heart and soul of a country.
With an eye toward the future, I take an active interest in the latest technological developments that are shaping our world. As a professional who primarily works online, I am constantly curious about how technology can be harnessed to improve our lives and society at large.
In my free time, I indulge in the simple pleasures of life by baking sweet treats and hosting dinner parties with friends. And when I'm seeking a more introspective experience, I've found that walking alone along the Camino de Santiago is a profound and beautiful way to connect with myself and the world around me.

I’m passionate about helping people work better together—especially when it’s hard.
The moments that matter most in organizations are often the most uncomfortable: disagreement, uncertainty, competing perspectives, and high-stakes decisions. Yet these are the exact moments most people feel unprepared to navigate.
I care deeply about equipping leaders with the tools to handle those moments with clarity, curiosity, and courage.
I’m also passionate about bringing more humanity back into leadership—through storytelling, play, and real connection. Whether through applied improvisation, visual thinking, or facilitated dialogue, I believe learning should feel engaging, reflective, and alive.

The idea of sharing knowledge and listening to what other people have to say.
I love medicine and science. I love how art represents things and the impact that it has.
And I'm also passionate about the idea of erasing racism, misogyny, homophobia, transphobia etc. so we can live in a safer and more tolerant society.
