Kayte Graham is a founding director and President of the Kerr County River Foundation. With a background in agriculture and geography from Texas State University, Kayte operates a regenerative farm in Center Point focused on native habitat management and restoration. 

She founded the Kerrville Farmers Market in 2017 and Central Provisions community cafe in 2022, both strengthening local food systems and community connections. 

Following the major flood in Kerr County, Kayte recognized the need for informed advocacy for the river's long-term health, leading her to co-found KCRF.  She views the Guadalupe River as a vital connection between people, place, and nature deserving thoughtful stewardship.

 A Kerr County native and Center Point resident, he founded the Kerrville Urban Trail System, creating multi-use trail infrastructure that improves property values, emergency access, and community connectivity. As a local business owner, he has launched ventures that generate jobs and serve as community gathering spaces. His board experience spans healthcare, historic preservation, and nonprofit leadership. 

Jeremy's approach to the River Foundation combines hands-on conservation work with strategic planning—from leading the River Trail Extension program to co-developing educational River Short Films. He views the Guadalupe River watershed as critical infrastructure deserving the same systematic investment and protection as roads and bridges.
