I offer science-based Nutrition and Lifestyle advice that's been proven to work. 1:1 consults, on-line classes, and as a keynote speaker. In organisations, I speak on all thing's wellness (Work + Well series). Curated for professionals these are designed to empower people with the tools they need to stay well. Current seminars are: . Fuel your success (How to get the energy you need to succeed) . Stress RX (Resilience Remedies) . Work-Life-Hormone Balance (Female-specific advice for all ages including Perimenopause & beyond). I do all of this while continuing to contract in senior Project roles - so I live what I teach daily.
