Work with Katie

Hi there, I’m Katie and I’m Your Thyroid ND.

I am a Naturopathic Doctor with a clinical focus in thyroid conditions and Hashimoto’s Disease.

My mission is to break the mold of traditional thyroid care that leaves so many hypothyroid sufferers feeling forgotten and fatigued. I use my signature framework and a practical down to earth approach to help my patients feel like themselves again.

Rooted - Naturopathic clinic & iv therapy located in Barrie Ontario

Dr. Rothwell works with patients exclusively at Rooted Naturopathic Clinic, located in Barrie ON. To become a patient of Dr. Rothwell, you must currently reside in the province of Ontario. In person and virtual visits are available.

Why Thyroid Health?

1 in 8 women will be diagnosed with a thyroid condition in their lifetime. A year into my practice I discovered that I was one of those women, and was diagnosed with Hashimoto’s Disease. Along with many of my patients, I understand the vital role the thyroid plays and what can happen when it’s not optimal. Since then I have invested much of my time into educational courses and research to learn everything I could about the treatment of thyroid disorders beyond “just take this medication”.

I can’t count the number of women who come into my office with a similar story. It goes something like this: they were diagnosed with a thyroid disorder, told it was an easy fix, given medication, and went on their way. Years later, many of these women continue to struggle with symptoms like fatigue, weight gain, chronic pain, digestive issues, low mood, and more. They’re told their thyroid levels are “normal” and to simply exercise and eat better, or offered other medications like antidepressants.

If this sounds familiar to you, let’s talk.

If you’re feeling frustrated, ignored, and looking for answers, you’re not alone!

The Game Plan

It all starts with our first visit. We will do a thorough intake that covers your concerns in addition to any important health history and a brief physical exam. A complete thyroid and nutrient assessment may also be recommended. In 1-2 weeks we will meet again to go over findings and put a plan in place that works for you.

The thyroid is a complex hormonal organ. As a Naturopathic Doctor, my job is to get to the root of your concerns and provide you with a comprehensive plan to address your whole self.

In addition to thyroid conditions, I have also completed advanced training for the treatment of menopause as well as hormone replacement therapy (bio-identical hormones, menopausal hormone therapy, HRT)
