Launched in the fall of 2023, We Believe in Portland (WBIP) is an initiative co-founded by Thesis and AdoptOneBlock. What began as Litter League at Thesis, under the leadership of Ryan Buchanan and Carling Leon, has evolved into a thriving community effort that has engaged hundreds of companies and thousands of participants annually through its Spring and Fall cleanup events. The original purpose of Litter League was simple yet impactful: dedicate two hours on a Friday to cleaning up litter in a few city blocks, followed by supporting local restaurants by gathering for lunch.

Building on that foundation, the mission of We Believe in Portland is to mobilize businesses and individuals to take the first step in revitalizing our city by coming together to clean, restore, and inspire collective pride and lasting community impact.The initiative is powered by AdoptOneBlock, a 501(c)(3) nonprofit organization, which collaborates with a committee of staff and volunteers to plan and organize the events, manage logistics, and provide participants with the necessary cleanup supplies.
