Your Gut, Your Hormones, Your Life - Simplified.
About Dr. Kim Bretz, ND
I believe healthcare can be clearer, kinder, and more effective - without all the noise. As a naturopathic doctor, menopause-certified practitioner, and faculty at the University of Waterloo School of Pharmacy, I help navigate gut health, hormones, and lifestyle medicine with evidence-based, practical strategies.
For over 20 years, I’ve worked at the crossroads of gut health, midlife transitions, and modern integrative care - teaching, speaking, and working with patients to help them live fuller, less restricted lives.
How I Can Help
Whether you’re struggling with gut issues, navigating hormonal shifts, or simply tired of the “elimination diet life,” my focus is simple:
Clarity over restriction
Practical strategies over perfection
Evidence without the overwhelm
Through 1:1 patient care, practitioner consultations, corporate wellness events, and speaking engagements, I offer science-backed care that helps you feel better - not just follow more rules.

More Than a Naturopath
I’m also a curious foodie, outdoor adventurer, and someone who believes life’s too short to live on five “safe foods.” You’ll often find me kayaking Ontario lakes, trying new recipes, or calling out health nonsense on podcasts and social media.
Healthcare doesn’t have to be confusing
