Healing is the art of embracing our own wholeness, nourishing our body, calming our mind and connecting with our soul.

Lesley Nickleson, RD, IFNCP, MMI
Over 25 years of specialized experience in Critical Care and Oncology Nutrition, as a Certified Nutrition Support Clinician. Throughout my years in clinical practice, I have witnessed the profound role that nutrition plays in disease management.
​
In May 2023, I earned board certification in Integrative Functional Nutrition—a distinction held by only a few Registered Dietitians in Canada. Functional Nutrition has enriched my life, both professionally and personally, as I continue to explore the ways food, lifestyle, and mindset contribute to optimal body function.
​
Beyond my professional training, I am also a certified meditation and mindfulness teacher and a qualified Mindfulness-Based Eating Instructor (MB-EAT). Integrating these practices helps me to bring a truly holistic approach to my Personalized Nutrition plans and Coaching services.
​
Everyday I feel beyond grateful to share real results and transformation with incredible clients. From sustainable weight loss, better digestion and boosted energy to restored sleep and reduced stress- I am continually amazed by the power of nutrition. I would love to help guide you along a journey toward a healthier, more vibrant life.
