I was born in Sarajevo, Bosnia, and at 8 years old, my family immigrated to Germany to escape the war that unfolded in the early 1990s. A few years later, we moved again, settling in California, where I have now lived for 27 years.
Experiencing displacement, cultural shifts, and the challenge of rebuilding life twice over shaped the way I see the world. It deepened my understanding of human resilience, the weight of trauma, and the quiet strength that carries people forward. I have known loss and uncertainty, but also the beauty of adaptation, the power of connection, and the ability to find meaning even in hardship.
