Tunku Rafidah Mustapha began her professional journey as an early childhood educator. After retiring in 2003 from Garden International School, where she dedicated 20 years of service, she embraced a new challenge by joining NASAM as a volunteer. Her passion and commitment played a pivotal role in establishing the NASAM Ampang Club, where she later assumed the position of Chairperson — a role she continues to hold.

Under her leadership, the Ampang Club has grown significantly, reflecting her unwavering dedication to its mission. Beyond her work with NASAM, Tunku Rafidah is a fitness enthusiast who enjoys water sports. While she once embraced the thrill of jet-skiing and water-skiing, she now prefers calmer activities such as rowing and snorkelling. An advocate of active living, she also finds joy in walking and is an avid practitioner of Nordic walking.
