I was an active sportswoman from a young age with swimming and running being a big part of my life. Running and staying active is currently still a big passion of mine which I do almost daily. I have a passion for sports nutrition with a focus on helping athletes achieve their best results by optimising their nutrition. I am registered with the Health Professions Council of South Africa (HPCSA) and the Association for Dietitians in South Africa (ADSA).
