Fondly dubbed the “Double Energy Twins,” they have made it their mission to teach children and adults the importance of maintaining a healthy lifestyle. In addition to being interviewed on numerous radio and TV shows, Judi and Shari have lectured on the topic of health and nutrition throughout the United States.
