Nadya Okamoto is #PeriodProud. Launching her global "Menstrual Movement" inspired by her own personal struggles and the feminine hygiene struggles of homeless women, the Harvard student brought significant change and attention to period poverty in a few short years. From her nonprofit’s 2014 inception, PERIOD is now the largest youth-run NGO, as Nadya’s efforts earned her a place in InStyle Magazine’s "The Badass 50: Meet the Women Who Are Changing the World." Leveraging the first-ever historic #nationalperiodday in 2019 through social media, the Twitter-trending rallies across 50 states and 5 countries became the largest grassroots mobilization for period activism in history.
