David Kennedy
Strategic Co-Chair
Emerging Leaders Board

David teaches high school science and math with Portland Public Schools, and believes in the importance of cultivating STEM literacy in our society.

David has held leadership roles in a variety of nonprofit organizations before joining the ELB, including 350PDX, Bike Farm, and King Neighborhood Association. He strives to keep intersectionality, equity, and climate justice at the forefront of his climate work. When not working in the community, you might find David riding his bike around—or out of town—eating burritos, or enjoying the glorious nature that the northwest has to offer.

Clement Uduk
Strategic Co-Chair
Emerging Leaders Board
Native Portlanders are a rare breed as Portland continues experience an incredible influx of transplants from around the country. Clement Uduk is one of these rare individuals. As a youth, his passion for golf and being outdoors, along with his curiosity in science and math, led to him wanting to become a conservationist and environmentalist. He received his bachelor’s in environmental science from the University of Portland. Clement has knowledge and interesting in GIS and water resource issues, recently completing a graduate certificate in GIS at PSU. Currently, the jack-of-all-trades-and-interests works as a middle school integrated science teacher. When this guy isn’t teaching, you will most likely see or hear him celebrating (or bemoaning) being a Trail Blazers fan, discussing his fantasy baseball or football team, telling you why he thinks Drake is overrated or out at Colwood playing some par 3 golf.
Elizabeth Silberg
Liaison to OEC’s Board of Directors
Emerging Leaders Board

Elizabeth Silberg believes if you have a better balance, you achieve a healthier whole — that is, the best version of yourself. Then again, if you don’t go too far, it will be hard to find your limits. So she always takes on a challenge that offers an opportunity to help her be a better person.

Elizabeth is a Director of Digital Product Management and Transformation at IBM, and before that, held roles ranging from the most established areas of the business to the most nascent. This includes transforming IBM to a new way of working, identifying and validating new ideas for Smarter Cities products, driving Agile transformation and managing common services in the Rational brand, developing cross-brand tooling within IBM’s Systems and Technology Group and building IBM’s strategy in Software. Through these roles and patent submissions, she discovered her penchant for fixing things through integration, efficiency and empowerment — building organizational capability and self-directed teams through trust, empowerment and support, as well as connecting dots, systems and people into cohesive, stronger units.

She is the Finance Chair and Treasurer on the Board of Directors for Saturday Academy and also volunteers with various other education, empowerment and environmental organizations. She likes to experiment with different training for mind, body and well-being, so you might also find her on the stage, in the gym or out with nature.

While studying at the University of Colorado Boulder she worked on campaigns to protect public lands in Utah, to bring awareness to the dolphin’s plight in Japan, and to support grey wolf conservation across the state. After visiting Oregon for an environmental law conference she was hooked; the lure of old growth forests and coastal waters brought her here for good. Now she serves as the Office and Event Manager for Oregon Wild where she works to bring people together over the love of wildlife and wild places. Outside of the office you’ll find Gaby making jewelry, watching a movie at the Hollywood Theatre, or out on the trail with her dog Lacey.
