YEJA Community Organizer

Kevin is a storyteller and student leader based in traditional Kalupuya, Confederated Tribes of the Grand Ronde, and Atfalati lands (Beaverton, Oregon). Their work centers around the intersections between their ethnic identity as a Black American and Samoan person and their gender fluidity. Kevin uses their platforms to interrogate systems of power, challenge normalcy, and uplift voices within their communities. Through interpersonal connection, community organizing, poetry, and education, they have found space as an emerging voice for Black, Indigenous, queer, trans, and climate liberation.

Calaix Alexander
She/Her
Finance and Operations Director

Calaix (like "ballet") has been a social justice warrior from an early age. She is warm, yet assertive and passionate in her care and support of our most marginalized community members. When she's not streamlining systems, you can catch Calaix cracking jokes on stage or slaying monsters in Dungeons and Dragons.

Pedro Evenezer
They/Them
Trainings Coordinator

As a young person, Pedro's climate awareness was first nurtured by the thoughtful instruction of early educators and then ignited by their first hand experience living through some rather intense climactic events. As an adult, Pedro hopes to build community power through collective skill sharing and escalated actions. They care deeply in the tradition of knowledge & resource sharing, and its transformative ability to help others realize their own agency & autonomy. When not vigorously typing away at a computer, Pedro enjoys riding their bike, reading, and dancing.


Ellie Gluhosky
She/Her
Campaign Organizer

Ellie got her official start in community organizing in her beloved college town, Missoula, MT, where she focused on movement building primarily around housing and environmental justice, and voting rights. During the Covid-19 pandemic, she switched from organizing to direct service work to help community members secure housing. She is thrilled to be back in an organizer role and eager to continue advocating for and with her community. Outside of work, she can be found on top of the nearest mountain, or horizontally on her couch watching and reading copious amounts of nerd content.


Abby Griffith
She/Her
Bus Riders Unite! Community Organizer

I am a person with a disability, and I rely entirely on public transit to get around. I am committed to advocate for a better transportation system in our city, because I strongly believe that those of us who cannot drive also have a right to get where we need to go safely. My vision is to bring our community together and advocate for safer, fareless transit. A fun thing about me is I love traveling, especially taking the local bus to explore nature!


Lee Helfend
They/Them
Executive Director

Lee has been organizing against dominant power structures for over a decade in several different realms, from student organizing to labor organizing, from political campaigns to everyday acts of resistance. They are deeply committed to centering relationships, care, and appreciation in community organizing spaces, and believe the messy, complicated, untold parts of our stories hold the power that is necessary to change how we think about systems, culture, and each other. On any given day, you can find them strutting in heels too high, chasing the sun, and writing about the worlds we wished we lived in.

Valerie Goodness
She/Her
Board Member

I have a master's in natural resource sustainability, and a PhD in American Indigenous studies, where I work to protect or restore culturally significant landscapes, foods and medicines for this continent's First Peoples. I would like to see more BIPOC inclusion in all levels of environmental justice from the boardroom to the laborer. Being outdoors, beading, gardening, and crafting is my jam!


Tristan Isaac
He/Him
Interim/Vice Chair, OPAL Board of Directors

Tristan first got involved with OPAL in 2017 as an organizer-in-training and quickly became an active member of Bus Riders Unite before joining the steering committee and OPAL Board of Directors in 2019. Now as Vice Chair of the Board of Directors as well as the BRU representative on TriMet's Transit Equity Advisory Committee, Tristan seeks to promote a vision of robust, accessible and safe public transit as an all-encompassing strategy to address climate change, air quality, pedestrian safety, urban mobility, social atomization and much more. Tristan enjoys critical media analysis of all kinds, anarchist theory, afrobeat music and listening to podcasts while playing indie video games.


Deborah Olson
She/Her
Bus Riders Unite! Steering Committee

I have been doing volunteer work since the last century (Yes, I am that old!). I joined OPAL and Bus Riders Unite! around when BRU persuaded TriMet to allow more time on a single bus ride fare. Since I am in my 60s, I'm concerned about leaving this planet in good shape, with cleaner air and giant trees for future generations.
