Jennifer joined the Green Lake Association in January 2019 as the Communication and Project Manager. She holds two Bachelor of Science degrees in Biology and General Science, and a Master’s in Environmental Studies from Virginia Commonwealth University in Richmond, Virginia.

While at VCU she taught undergraduate biology labs as an adjunct professor, conducted research on amphibian development and worked as an administrative assistant and undergraduate advisor.
