At the same school she also completed advanced business curriculum to channel her passion and knowledge into a strategy. Geili is contagiously positive and full of life. She is most passionate about helping others to live healthier and happier lives!

She has been into wellness since her younger years. Her deeper interest in nutrition was sparked during her modeling career where she often encountered highly dysfunctional relationship with food which was often seen as an enemy and rather a tool to make one sick instead of healing. From there on she decided to learn nutrition more in depth, because she strongly believes food is meant to heal and bring joy into one’s life.

Geili specializes in empowering people to create and maintain a healthy lifestyle supported by sleep, stress management, nutritious food, mindfulness practice, movement, and healthy relationships. She also teaches women how to heal the relationship with food and their bodies, and ditch the diet circle for good. Geili’s role is to guide one’s journey toward greater wellness, energy and vibrancy. Her holistic approach considers all aspects of one’s health—body, mind and spirit. She treats each individual as unique, and based on individual needs she helps to find unique nutritional requirements to reach one’s optimal health.

Outside of her nutrition career, Geili loves traveling, being outdoors, running, doing yoga and pilates, baking, trying new recipes and reading.
