Credo High School


GSE Credo students are currently advocating for a farm within biking distance of their campus where they will have the opportunity to learn more about sustainable agriculture. Many GSE students at Credo are also sustainability captains for the OnePlanet program, a program that abides by 10 principles of sustainability to live within the means of one planet’s natural resources. Credo puts on a county-wide event once a year called the OnePlanet Youth Summit where students can learn all about the environmental organizations that exist locally. The Credo gardening class also received a grant from U.S. Fish and Wildlife Service to plant a native habitat garden in front of their school.

Meet Your Educator, Harlie Rankin


Harlie is from Washington and graduated from Seattle University with a BA in Environmental Studies focusing on Urban Sustainability, and minors in Spanish and Public Affairs. She was first introduced to Global Student Embassy when she went on one of our trips to Bahía, Ecuador with her university. Harlie went on to work as an Exchange Coordinator in Ecuador, leading several trips in Bahia and Cuenca.

Harlie now works with four high schools and, most notably, the Village Park garden, a 1/2 acre community garden in the heart of Sebastopol. The Sonoma GSE program is deeply rooted in the county’s unique agricultural and environmental leadership network, and students work closely with other organizations to best address issues in the community.  Harlie is passionate about raising up the leaders of tomorrow and best equipping them for the environmental and social challenges that lie ahead.
