After graduating in 2009 from Union College, in upstate New York, Parker began his career as an energy efficiency engineer, working for the state to implement incentive programs for green technologies in building construction. After moving to Washington in 2011, he continued his engineering work in the aircraft manufacturing industry. In 2013, wanting to pursue a career in education, Parker left engineering to become a teacher. First as a long-term substitute and then as a full-time teacher, Parker taught science and math at Seattle's Bishop Blanchet High School. Since the Fall of 2014, he has worked at The Attic Learning Community, in Woodinville, where he teaches math, physics, and philosophy. Parker holds a master's degree in engineering management and two bachelor's degrees, in mechanical engineering and philosophy.

Parker has had a life-long passion for working with kids. Even before becoming a teacher, he worked for many years as a tutor and has spent 10 of his summers working at various camps and summer programs for kids. Very little gives him as much joy as helping young people on their journeys to adulthood. Concern for his students' future is one of the principle motivations behind Parker's candidacy.

In his free time, Parker enjoys playing the flute and working on building projects. He has always loved the water, and has personally built several sailboats of his own design. He is also an avid chess player. Parker lives in Woodinville with his orange tabby cat, Spark.
