The Organization

The mission of the Matanzas Riverkeeper is to protect the health of the Guana, Tolomato, Matanzas watershed through advocacy, education, and community engagement. 

Matanzas Riverkeeper is a 501(c)(3) organization founded by Neil Armingeon in 2013 to protect the fragile and beautiful Matanzas River. Neil served as the Matanzas Riverkeeper for four years until his retirement in December of 2017. Neil dedicated his entire career to acting as a voice for our imperiled natural resources. You can read more about Neil’s journey here.

Matanzas Riverkeeper is a project of The Friends of the Matanzas, a non-profit organization that has been fighting to protect the Matanzas River since the early 90s. Since its inception, Friends of the Matanzas has spoken out against poorly planned developments that would harm the Matanzas River or its tributaries.


In 2017 Friends of the Matanzas incubated a second project, Matanzas Voices, a multimedia oral history project telling the stories of life along the Matanzas River. This project will document and preserve the lived experiences, recollections, and impressions of the people whose lives and work on the Matanzas River have shaped the cultural landscape of our region.
