It is with sadness and regret that we mourn the loss of Donna Olsen, an original organizer of the Tri-City Ecology Center in 1971. Donna served on the initial Board of Directors and continued to serve until her recent passing. She filled every position at some time, but her prime role for decades was to be the editor of Eco-Logic, TCEC’s monthly newsletter. She was respected as a community activist, an environmental leader, an opinion shaper and a model for others to emulate. She was a true gem of Fremont, and a part of its long history, and she will be sorely missed. Read more about Donna’s many contributions to TCEC and our community.
