Our History

Back when social media users were posting scenic photos and selfies on their Instagram, Trimnell had discovered an online sickle cell community.In an effort to educate herself and others living with the condition, Trimnell shared her in learnings in digestible graphics, at the time, an innovative way to reach others and strengthen the digital community. Soon after, Sickle Cell 101 was founded in 2013 and 10 years later the goal still remains the same – to provide accessible sickle cell education for all.
