Thank you for being here. I launched   Latinos in STEMM Rising   with a clear goal: to inform and empower Latino STEMM leaders, break persistent barriers, and advance Hispanic education in medicine and science, with data and lived experience at the center. In 2025, that mission found its audience. This community grew to   800+ subscribers on LinkedIn   and   ~900 readers on the blog , with conversations extending far beyond this newsletter into classrooms and labs. Along the
