Meet Isabel!

Hi, I’m Isabel! I’m a passionate, life-long health and wellness lover and am living the dream I’ve imagined since I was 11. All my life I’ve had a profound passion to help people be well and thrive and have found that food can really be healing and health-promoting if we allow it to be.

As a child, I had chronic stomach aches and a million food allergies (red foods, eggs, wheat, dairy)- and I was also an athlete, so finding food that worked for my body and felt good at the same time was (and is) always really important to me. Though I’ve certainly had my own food struggles, throughout my teens, twenties, and into my thirties, I’ve certainly found a wonderful place for the food that makes my body and mind feel good, and especially for my dessert (if you follow me on social media you’ll see that!).

My philosophy is built on the premise that most of our bodies do better with more plants, more movement, and fewer processed ingredients, but the specifics of how each of us live is completely different because we all have different needs.

I/we work with each of my clients closely to help them improve their ability to learn, listen, and provide for their bodies needs, and in the process improve their relationship with food and with themselves. We’re dedicated to helping each one of our clients free themselves from dieting and look at eating as an inclusive activity versus the traditional exclusive dieting model, no matter what their health goals might be.

I’m so excited for you to learn more about how me and my team can help you live a happier and healthier life!
