Hi, I’m Domina Elfrida Silitonga. I was born in Serbelawan, a small village in North Sumatera. I earned my bachelor’s degree from the State University of Medan and my master’s degree from the State University of Jakarta. I love teaching, and over the years, I’ve had the chance to teach in different places across Indonesia—Medan, Batam, Jakarta, and Bali. In addition to teaching, I love traveling. Exploring new places and cultures is something that inspires me both personally and professionally. Currently, I teach Mathematics at Amman Academy, and I’m grateful to be part of a collaborative and enriching school environment. It’s been an exciting journey, and I look forward to continuing to learn from both my students and colleagues in this new chapter.
