Creation of UrbanPlay is based on her research during her graduate studies, experience working with kids through various organizations and also her many years of experience working as personal trainer and health coach with the adult population. Furthermore, her passion to create UrbanPlay is fueled by her own transformation from being an overweight and sedentary kid.

Andra Enoiu
Andra’s passion for fitness began in high school where she competed in cross-country and track and continued to develop when she discovered how cross training could prevent injury and help her reach her running goals. She currently offers personal training and fitness classes throughout the Bay Area. As a fitness instructor she fosters a supportive and welcoming environment so that members leave each class feeling stronger, healthier and more confident. She believes exercise needs to be fun and exciting in order to engage others, especially youth. Simply, you have to love it do it. When she worked as a camp counselor in LA County, she witnessed sedentary children who were more interested in playing video games then running around and playing active games. Her goal is to make UrbanPlay the best part of a child’s day so that they continue to make their health and fitness a priority in their lives.
