Mrs. Sesepasara-Williams

Assistant Principal

Aloha and welcome to a new and exciting school year!  I am excited to start this journey with all of you. A little bit about myself, I have been with the Hawaii Department of Education since 2003. I received my Bachelors in Education from the University of Arizona in 2001 and my Masters in Education from Chaminade in 2005. I have worked in the elementary field for 17 years both as a teacher and Curriculum Coordinator before moving to administration. I spent last year as a Vice Principal at Moanalua High School and am happy to return to the elementary field. 

My philosophy in regards to the education of our keiki is this: I truly believe that our purpose as educators is to empower students to take charge of their own learning and that the delivery of it should be innovative and come from a place of compassion and empathy. We must actively involve our families and communities to work together as a collective to provide our students with a quality education as well as social-emotional support that will guide our students to reach their individual potential. Empowering our keiki to take charge and responsibility for their own learning and futures will result in providing them with the necessary life skills that will help them succeed regardless of their background or the path they decide to take after high school. If we work together, we can fulfill the school’s vision, “Momilani Elementary students are caring, responsible, and self-directed learners who positively contribute to society.”
