Sheridan Gemuendt
Climate Ready America Southeast Regional Coordinator
As the Southeast Regional Coordinator for Climate Ready America at the Geos Institute, Sheridan is passionate about helping communities build the connections, capacity, and access to resources they need to navigate a changing climate. She brings nearly a decade of experience leading sustainability and resilience initiatives in Florida local government, where she guided cross-departmental efforts, advised elected officials, developed sustainability and climate action plans, and built partnerships to turn big-picture targets into practical action. She is a Certified Climate Change Professional (CC-P) and a Prosci Change Management Practitioner who enjoys bringing people, ideas, and systems together to create lasting change.
With a B.S. in Biology and an M.A. in Humane Education, her education provided a foundation for her belief that environmental, social, and animal well-being are deeply interconnected, and that meaningful change begins when we recognize ourselves as part of our respective communities and ecosystems. A huge native plant enthusiast, Sheridan previously spent several years managing a community garden and worked as a garden consultant, teaching gardeners across the Southeast how to grow food at home and incorporate native plants into their landscapes.
Outside of work, Sheridan can often be found outside exploring with her husband and two young daughters, discovering the plants, landscapes, and small wonders that make a place unique. More than anything, her commitment to climate work is driven by the desire to create a more hopeful future for her daughters and children across the world.
