Vanessa is a Certified Nutritional Practitioner. Deciding to pursue her passion for health and fitness, Vanessa enrolled at the Institute of Holistic Nutrition, where she received her diploma with highest honours. After completion of her program, she continued her education and received her certification in Naturally Designed Pregnancy & Early Childhood Nutrition. Her passion for working with children has developed from teaching competitive dance for the past 12 years.


As a professional dancer, Vanessa experienced first hand the lack of education available on how to properly fuel your body. There was little to no information being presented regarding energy-sustaining food and injury prevention. This ignited Vanessa to empower individuals to live a healthy, active lifestyle using the power of proper nutrition. She focuses on maintaining balance throughout the body by reducing inflammation, restoring gut health, and improving energy levels. Vanessa uses an attainable approach to achieve optional wellness through whole foods, supplementation, mindfulness & exercise, evaluating individual’s complete health history, lifestyle, and nutrition choices to determine the root cause of their health concerns or imbalances. Vanessa is very excited to be joining the McAllister Health family, and looks forward to assisting you on your journey of holistic health.
