Cassia Tierney Clarke is a British author, content creator and host of the 9 Lives podcast, a show about identity, reinvention and the many lives we live in one.

After losing 100 lbs and becoming a marathon and ultramarathon runner, Cassia built a community through her honest account of transformation and everything that happens beyond the before-and-after photograph. A qualified personal trainer with a degree in film, she pairs lived experience with a distinctive storytelling voice, bringing wit, humour and a little darkness to conversations about change.

Her work spans fitness, fashion, beauty, travel and literature, alongside candid reflections on mental health and being diagnosed autistic at 32. Across the podcast and beyond, she explores what it means to rebuild, outgrow old identities and create a life that feels truly your own.
