He attended public schools, UH-Manoa (B.A.), Pacific School of Religion (M.Theol.), and earned his Ph.D. in Education as UH-Manoa. He is currently on the staff of Kokua Kalihi Valley Comprehensive Family Services. His work focuses on the intersection of working class experiences and social movements of liberation. He hopes someday to establish a center to promote his vision and work. At Journeys to Wellness V on Oct. 22, 2016, he led a workshop on the development of Nakem pedagogy as a praxis for healing.
"This works will center on the development of Nakem Pedagogy as a praxis for healing. It will be led by students and nakem practitioners who will share their findings in dealing with trauma both personal and historical in addressing the collective healing of our communities. Participants will be invited to share their story. The workshop will explore historical trauma as a starting point of healing."
