A REGISTERED DIETITIAN
who actually gets it.

You're looking for someone who understands that your brain and body don't run on a neurotypical schedule, and who won't hand you a rigid diet plan and call it care. That's the work I do here.

THE PATH THAT
led me here
WASN'T EASY.

My brain was fast and creative, but also foggy, overwhelmed, and tired. My body felt unpredictable, and my energy and capacity shifted in ways I couldn't explain. No matter how many professionals I saw, no one seemed to be looking at the whole picture.

Behind the Scenes

For years I saw practitioner after practitioner who never spoke to one another.

 

I was handed prescriptions and long supplement lists with no real plan — I left most appointments more confused than when I arrived.

 

I've navigated anemia, insulin resistance, perimenopause, body shifts, poor sleep, brain fog, and chronic overwhelm.

The Shift

Everything changed when I was diagnosed later in life as an ADHDer, raising an AuDHD teen.

 

As I came to understand sensory needs, interoception, time blindness, and executive function, my whole life started to make sense.

 

I finally understood why traditional healthcare had felt so rigid, and why it was never built for spicy brains.

Why a Registered Dietitian Matters

My frustration, and my curiosity, led me to Integrative and Functional Nutrition — a whole-person, root-cause approach that looks at how hormones, digestion, inflammation, stress, metabolism, the nervous system, and the brain all connect. I wanted to understand why symptoms happen, not just how to manage them.

​

Today I'm a Registered Dietitian with over 20 years of clinical experience, and one of a small group of Canadian dietitians with the advanced Integrative and Functional Nutrition Certified Practitioner (IFNCP) credential. What that means for you is simple: a Registered Dietitian who can look deeper, ask better questions, notice the patterns others miss, and turn complex science into gentle, staged steps that fit your real life.
