Early life Sheila Atim was born 1991 in Uganda and moved to the United Kingdom with her mother at the age of five months. She grew up in Rainham, London, and attended the Coopers' Company and Coborn School. She did some occasional modelling as a teenager after being recruited when she shaved the side of her head for a school prom. She appeared in a 2009 London Fashion Week event, All Walks beyond the Catwalk, organized by the British Fashion Council to showcase clothes for "real women". She later said that "modelling was never a big earner for me. I was unusual looking, so I couldn't go for commercial castings." Career Theatre Atim graduated with a degree in biomedical science from King's College London and trained as an actor at the Weekend Arts Centre in Belsize Park, London. She became involved in a workshop for a new play, The Lightning Child, which led to her being cast by her acting teacher Ché Walker for her professional acting debut at Shakespeare's Globe in 2013. In 2020, she told the King's College alumni magazine that "I look back and feel a strong connection between my scientific and artistic sides. Science often comes up in my work – even the way I approach things in the rehearsal room is affected by having taken BioMed. Sometimes it’s little private parallels and analogies I make
