Ketty Munaf Rosenfeld is a highly regarded Zumba teacher and the inspiration for this film. Growing up in Indonesia where she was raised in part by her Egyptian grandmother, Ketty came to the U.S. to further her education and married a resident of Newton, MA. For many years she served as the Director of International Education at Northeastern University before beginning to teach Zumba in the Greater Boston area in 2015. She is interested in dance forms from around the world and welcomes all who come to dance with her, many of whom are also immigrants. In 2022, at her daughter’s urgent request, she and her husband relocated to Los Angeles so that Ketty could play an active role in the life of her first grandchild, as her own grandmother had done with her.
