I'm Crystal Sullivan, the IB coordinator at Denton High School. I've held various roles at DHS since 2016, starting as the MYP coordinator and transitioning to the DP coordinator position in fall 2022. My journey in education began in 2000 as an English II teacher at Little Elm High School and later teaching 9th-grade World Geography at Lewisville High School North for 9 years. Subsequently, I served as a district technology instructional coach before joining Denton ISD to open Betty Myers MS as the Digital Learning Specialist (DLS). Since 2016, I've been at Denton High School as the DLS until my move into the IB coordinator role. I'm deeply committed to the mission of the International Baccalaureate and its positive impact on our students at Denton High School. I'm honored to have this opportunity and look forward to supporting the DHS community for years to come.
