From a Personal Journey to a Passion for Empowerment

Bold Slim began in 2022 when founder Nellie, after experiencing her own weight gain challenges and frustration with traditional methods, sought effective alternatives. Inspired by the holistic approach and transformative results she found at Rozess, Nellie brought this vision to Centurion, establishing Bold Slim to offer cutting-edge body contouring and wellness solutions closer to home. Her firsthand experience fuels Bold Slim's commitment to understanding and supporting each client's unique journey.
