Registered Holistic Nutritionist
Brigitta is a Registered Holistic Nutritionist and Certified Blood Analyst in Kelowna BC. She joined the team at Diversified Rehabilitation Group in the spring of 2018 and leads the meal planning and nutrition education component of the TSRP and ADRP residential programs.
Brigitta is a self-proclaimed foodie, and the kitchen is her happy place. However, after many years of studying nutrition informally, and overcoming a health crisis of her own, she realized she needed to undo a lot of what she thought about food and health and rebuild based on what her body really needed – and what was harming it. She decided to follow her passion professionally and studied at the Canadian School of Natural Nutrition. Having completed many more specialized courses her focus is on optimal digestion, gut health, and the gut-brain connection.
“The body has an innate ability to heal itself if given the opportunity; healing itself from chronic fatigue, mood disorders, digestive concerns, and a host of other health issues. Nourishing food, movement, time for play and inner reflection, a supportive community, and adequate rest can have a huge impact on your overall health and well being. I feel strongly that if we claimed back our kitchens and food sources we can claim back our physical and mental health as well”.
Outside of learning and continuously upgrading her knowledge in the natural health field, Brigitta loves to host friends, get creative in the kitchen, run and hike our beautiful Okanagan trails, and travel with her family.

Hey hi hello! My name is Stanley (he/him/his) and I’m a yoga, mindfulness, and fitness instructor here to support your journey. A bit about myself – I attended UBC Vancouver where I completed my B.Sc. specializing in Cell and Developmental Biology. I am also former competitive dancer and hobbyist runner. My education and experiences have informed my understanding of movement as medicine. In my free time you’ll find me hiking any hill or in a heated yoga studio, especially when the weather gets cooler. If I’m not adventuring, I’ll be playing a board game, reading with an iced coffee, or tending to my houseplants. But enough about me – I look forward to connecting with you and hearing your stories!
