Tuyen’s favorite quote: “Plan your work for today and every day, then work your plan.”

Ms Quynh Nguyen is Mr Tuyen's wife. As a dedicated and wise mother, she strongly believes that a good school with good curriculums and a vibrant learning environment is the best preparation for a child before he/she enters into a wider world and becomes a global citizen. With such a vision, together with her husband, Quynh founded Renaissance International School Saigon in 2007.

Quynh is a successful businesswoman. She has been the founder and CEO of Viet Huong Flavour & Fragrance JSC. since 1995, a leading Flavor and Fragrance Company in Vietnam. Quynh defines herself as a businesswoman, a greatly devoted mother for her children's comprehensive development and an art lover.

Quynh also founded the Nguyen Art Foundation, an initiative dedicated to the preservation and promotion of art, both within Vietnam and abroad. The Nguyen Art Foundation aims to link artists working in Vietnam with opportunities to participate in international dialogues, and to assist them in navigating the global exchanges which can enrich not only their individual works and practice, but also the Vietnamese art scene as a whole.

Tuyen and Quynh have four children who all study at Renaissance International School Saigon. Thy Nguyen and Duy Nguyen studied at the school for 5 years before they moved to the US. The two younger boys, Chuong Nguyen and Kha Nguyen, are studying in the Secondary Division in this dynamic and excellent school.
