NWP was founded in 2001 by Christian Sinderman. Working with a great team and outstanding clients, we've grown over the past 15 years to the be the most successful political and strategic communications firm in the Northwest.
A native of Michigan, Christian moved to Washington State in 1998 to coordinate statewide field and Get-Out-The-Vote activities, transitioning by 1999 to helping recruit and later direct U.S. Senator Maria Cantwell's upset victory in 2000.
An incurable generalist (some would say unfocused), Christian works with candidates, issue campaigns, policy challenges, crisis communications... pretty much anything where he can apply his energy and experience.
Christian lives in Seattle with his family and a variety of pets. When not working, Christian enjoys coaching middle school sports, travel, soccer, photography and live music. He has a degree in Sociology and an M.S. in Environmental Policy from the University of Michigan. (Go Blue!)
Erin joined NWP nearly a decade ago from her native California, where she worked for the successful re-election campaign of Senator Barbara Boxer, as well as issue and ballot measure campaigns.
At NWP, Erin's increasingly large portfolio includes serving as a lead for complex issue and initiative campaigns, working with candidates on planning, budget and strategic execution, and overseeing direct mail and online production work.
Erin lives in Seattle with her family, and a cat. Outside the office, Erin volunteers with vulnerable children, and enjoys travelling-- typically to beaches. She has a degree from UCSD.
Mari joined Northwest Passage after four years at the Democratic Legislative Campaign Committee (DLCC) where she most recently served as Political Director, overseeing wins in nearly every state in the West. Prior to the DLCC, some of Mari’s earlier experience includes working in the office of Congressman Peter DeFazio in Washington, DC, and as Campaign Services Director for the Oregon House Democrats in her home town, Portland, Oregon.
Through Mari’s work nationally, she built up an impressive network of relationships in all sectors of politics and is particularly adept at working with stakeholders and allies. At NWP, Mari is our lead on legislative and other candidate campaigns and brings a personal flare to every race she works on.
When Mari isn’t politicking, she teaches fitness classes at The Bar Method, and raises money for local non-profits as an NAA Registered Auctioneer. She enjoys traveling, and spending time with her family. Mari has a degree in Political Science from PSU.
Tai Yang Abreu
Tai is an avid consumer of political news and content, having spent much of her college years slunk over a laptop, nursing a third cup of coffee, and dissecting legislation in the halls of Olympia. As a former lobbyist with the Washington Student Association, Tai specialized in content analysis, visual media communications, and campaign strategic planning. She eventually focused her efforts at home in Seattle, where she worked with the Washington Won't Discriminate campaign against I-1552 as a youth event coordinator, and then quickly jumped onboard Teresa Mosqueda's successful campaign for Seattle City Council as her field director.
Following the conclusion of the campaign, Tai entertained a few offers, but realized she was already right at home at NWP. She is thrilled to assist the team as a content and advertising developer.
A native from the Dominican Republic, Tai enjoys travelling to visit her family, raising the social media profile of her beloved dog 'Pirate', and spending time with her partner in their West Seattle home. She holds a B.A in Global Studies from the University of Washington.
