Miss Missouri Teen USA 2025 Mailyn Marsh is a proud student at Ozark High School, where she stays actively involved in both academics and leadership. She currently serves as President of the Kindness Club and is a member of eight other organizations, including—but not limited to—YEPO, Student Council, FCA, Key Club, and HOSA, where she was one of the first students from OHS to qualify for state and proudly placed 4th. She is also the reigning State Champion for Educators Rising for a presentation she created advocating against fast fashion. Additionally, she is a dedicated member of the school’s tennis team. Maintaining honors status while balancing these activities is something she takes great pride in.

Mailyn is passionate about education and empowering young women. Advocating for period poverty in her community has become a meaningful part of her journey, as she wants to ensure all future leaders are able to attend school. To help achieve this, she has been working to organize and promote menstrual product donation drives with The Diaper Bank of the Ozarks, so that no girl has to miss school or work due to lack of access to essential products.
