Hae-Sin has been the CEO of EFC for seven years and brings 25 years of K-12 public education experience to this team, most of those years in Oakland, California. Her focus before joining EFCPS was in the turnaround space – working with school districts and charter management organizations to recreate their lowest-performing schools as the CEO of urbanED solutions. She was also a lead organizer and co-founder of GO Public Schools, an education advocacy group and watchdog. Prior to that, Hae-Sin worked for the Oakland Unified School District as a teacher, principal, school developer, and executive officer. She led a team charged with designing and leading two foundational tenets of OUSD’s nationally-recognized reform effort – creating quality school options for families in every neighborhood and ensuring high-performing, more personalized communities of learning for children. She facilitated the design and opening of 22 new schools, replacing 18 chronically-failing schools.
She was the founding principal of ASCEND, one of the five original new small autonomous schools, a school recognized for accelerating achievement and engaging community. Ms. Thomas started teaching in Oakland in 1993 as a Special Education teacher at Bret Harte Middle School. She holds a B.A in Economics from the University of Pennsylvania, a Master’s in Curriculum and Instruction from the University of San Francisco, and a Master’s in Administration, Planning, and Social Policy from Harvard University. She was born in South Korea and resides in the East Bay with her husband, two children and Formosan Mountain Dog.
