Casey Lewis is the creator of the Substack newsletter After School. However, before she was writing to an audience of tens of thousands, Lewis was writing about youth trends on her blog Teen Fashionista. Later on, she started at Teen Vogue as an intern, and over the course of her time there, she worked her way up to senior digital editor. She left Teen Vogue to create Clover Letter, a daily newsletter for teen girls, which gained traction quickly and eventually got acquired by AwesomenessTV. Lewis then transitioned to a senior editor role at New York magazine, but she missed writing. So in 2021, she put in her notice and started her youth-trend Substack publication, After School. Today, she continues to write her newsletter to dedicated readers, makes accompanying content on Instagram and TikTok, and uses her expertise in youth trends to consult businesses, from early-age startups to Fortune 500 companies.
