    COO, Brand Manager, Project Lead

    Ellie is the lynchpin of High Performance Dietitian, with a repertoire of professional strengths that spans customer service, business development, clinical knowledge and problem-solving insight.

    Combining her passion for mountain sports with a strong interest in food and nutrition (she’s the queen of meal prep and planning), Ellie brings a wealth of critical thinking skills to the High Performance Dietitian team. After completing a degree in Outdoor Leadership, Ellie’s ski seasons in France in her 20s only gave her more of a taste to live in the mountains, which led to her move to the French Alps in 2017. Ellie completed an advanced diploma in nutrition before moving to the Alps which, paired with her background in sales and product launches with pharmaceutical giant GlaxoSmithKline, means that she offers the HPD team valuable insights and drive for development.

    Ellie brings energy, passion and positivity to the HPD team and creates interesting and innovative working strategies that are made to fit the needs of every client…when she is not out skiing, climbing, running, ski touring, mountain biking, cross country skiing, hiking, and generally having fun in the mountains!
