ChangeStream Media’s mission is to use digital media to promote education, improve health, and advance social justice worldwide.

In 2011, Denise Miller and Sean Koenig collaborated with local organizations in Cambodia to create four Khmer-language videos that have reached scores of educators in formal training sessions. This content spurred changes in government policy, and inspired education leaders to implement improved teaching strategies in schools across the country.

Confident that small film crews using consumer electronics can create and distribute meaningful content, ChangeStream Media incorporated as a nonprofit organization in Washington state and became an Associated Program of Shunpike, a 501(c)(3) non-profit art service organization, in 2011.

Since then, our all-volunteer team has completed media projects in 13 countries, and taught digital storytelling workshops for nonprofits in Seattle.


ChangeStream Media’s guiding principles are:

  • Serving and centering the communities we partner with to create content
  • Sharing stories honestly and authentically to elevate change makers
  • Sustainable storytelling that builds the capacity of organizations and empowers individuals


Mural Project Honduras Children's Alliance
Mural Project Honduras Children’s Alliance

“Honduras Child Alliance is a volunteer-powered NGO providing educational enrichment projects to impoverished children in El Porvenir, Honduras. ChangeStream Media came to Honduras and created videos to assist with recruiting volunteers and project sponsors. In just a few short minutes they give a clear and upbeat depiction of our projects, and jumpstart the process of recruiting volunteers and sponsors. ChangeStream Media took the time to truly know our volunteers and the children who they work with, and their depiction of the genuine relationships shines through in both videos. We appreciate the work that was done and find that it positively impacts our projects on a daily basis.”

Rural preschool in Cambodia

“ChangeStream Media’s video work provides CCAF with a wider audience in the region, and connections to funding and technical support from around the world. The volunteers from IDEA Project, based in Hong Kong, viewed my fundraising video, and this has motivated them to work with children in rural areas in Cambodia. ChangeStream Media also made a video to help my staff improve their teaching. Because they provide information to donors about how we serve rural children, I believe we will receive more support through these documentaries.”

— Hing Channarith: CEO & Founder of Cambodian Children’s Advocacy Foundation
