Alexandria’s affinity for nature began during her time as an undergraduate at the University of Oregon where she soon began to pursue outdoor teaching as a field of study alongside her major in cinema. Alexandria began her career with Twin Rivers Charter School in 2022 as an AmeriCorps, expecting a temporary position and, instead, finding a home. She began as a full-time instructor the following year and has been with the TRCS ever since. When she’s not working, Alexandria is building aquascapes, going to the theater, swimming, camping, hanging out with family, and trying out new recipes at home.
