Born in Coos Bay, Teddy is a seventh generation Oregonian whose ancestor, Thomas Dove Keizer, led a wagon train over the Oregon Trail in 1843, and later had Keizer, Oregon named after his homestead. Teddy attended Brown University, and upon graduation he began his work in politics by helping to develop Patrick Kennedy's environmental platform in his successful run for Congress.

Teddy has continued to put his passion for social change into action. Over the years, he has helped in the legislature to update the Bottle Bill, fund Climate Masters, improve school nutrition, and set up a teacher mentoring program. In 2008, he co-founded Oregonians for Renewable Energy Progress (OREP). They have been working at forming a better financing mechanism, so renewables can replace fossil fuels as our major source of energy in Oregon. In addition, Teddy co-founded Orca Tutors. In partnership with the I Have a Dream Foundation, they have been bringing math tutors to scores of disadvantaged elementary school children. Teddy is on the board of NARAL, fighting for a woman's right to make decisions about her own reproductive health. As a member of Basic Rights Oregon's Finance Committee, Teddy has been raising money for a ballot measure to bring full marriage equality to Oregon's constitution. In addition, he has been on the Multnomah County Steering Committee for the Oregon League of Conservation Voters (OLCV). Through this work at OLCV, they have been strategic in getting environmentalists elected to office and held elected officials accountable once they are elected. He also has served as the Chair of Multnomah County Democrats, working to ensure that Multnomah County is led by Democrats.

Teddy's passion for the outdoors and wilderness conservation and his desire to bring people together to achieve a common goal led him to break eight world records in mountain climbing and ultrarunning. In 2000, he set the speed record for climbing all 55 of Colorado's 14,000-foot peaks, a world record that remains unbroken. Teddy also set records in the Adirondacks and Catskills in New York, the Barkley Marathons in Tennessee, and Vermont's Long Trail. He also completed a 50-kilometer hike in each state in less than 75 days.

Teddy and his wife Ann, who teaches eighth grade in Portland, have two young children. Today, Teddy can be found going door to door in the district to meet the citizens of inner Southeast and Northeast Portland to hear their concerns.

Teddy invites you to help him bring about a new era of progressivism and achieve lasting benefits for all Oregonians.
