About the Podcast

“Generations in Conversation” is an original podcast hosted by Dr. Simba Tirima (environmental health scientist, humanitarian, transformational leader, father) and his son, Gitari “Tari” Tirima (entrepreneur, innovator, emerging leader, and curious thinker). Recorded and produced in Nairobi, Kenya, the show offers a deeply personal, wide-ranging, and intellectually rigorous exploration of human flourishing, leadership, transformation, and meaning in the 21st century, bridging generations and cultures through open-minded dialogue, scientific insight, biblical wisdom, and lived experience.

Our Mission

To provide a radically honest, science-informed, scripturally-literate, and profoundly human podcast. Bringing together father and son, multiple generations, and listeners from all walks of life. We aim to dismantle the silos of discipline, age, and worldview by curating conversations and stories that challenge, inspire, and equip listeners to live purposefully, courageously, and authentically.
