Meet Our Founder

Gloria Tsang, RD founded HealthCastle.com in 1997 when her father was diagnosed with cancer. Being a registered dietitian, Gloria wrote and compiled cancer nutrition articles so that other families may also benefit from the information. Over years, HealthCastle has become the largest platform run by registered dietitians. Spreading the goodness of nutrition is our passion.
