Sherrie Jackson |Operations Coordinator

sjackson [at] confluencecenter [dot] org

Sherrie was born and raised in Southern California, but has called the Northwest her home for over 20 years.  She attended Portland State University where she earned a BS in Psychology and also worked in the Outdoor Program, where she found her passion for non-motorized sports and the environment.  After college was a crew leader for at-risk youth with Oregon Youth Conservation Corps.  She, along with other staff, started the Cascade Education Corps; an alternative high school that focused on service learning, environmental education and career development.  In 1994, she helped begin a new program called the Northwest Service Academy (NWSA); an environmental AmeriCorps program.  She worked for NWSA for 16 years taking on several roles, but focused on member recruitment.  Sherrie continued her education to obtain a professional certificate in Human Resources and hired over 1000 AmeriCorps members for NWSA. 

In 2011, Sherrie and other former NWSA staff created Confluence Environmental Center.

When she’s not working, Sherrie enjoys time with her family, playing soccer, rock climbing, skiing, backpacking and will try any crazy, mud run that comes within a 100 mile radius of her house
