Arlieta Hall was a full-time caregiver for her dad with dementia when she started going to open-mic nights around Chicago for some relief. Then one night a manager suggested that she tell stories about her dad on stage. Now, Arlieta is making her name as a comedian and dementia educator. She’s a fellow at Chicago’s famed Second City comedy club, finishing a film about care and comedy, and trains families and caregivers to use the tools of improv to communicate better with people with dementia.
