Our Story

I began eating a gluten-free diet in 2013 as an experiment and experienced decreased headaches, aches and pains, and IBS symptoms. However, as good as I felt, sometimes I found it difficult to get enough vitamins & minerals in my diet as well as find GF substitutes for my favorite foods (hello donuts & pizza!). I also felt like an outcast sometimes in social situations when I didn't eat what everyone else was eating. Since then, I became a Registered Dietitian and made it my mission to become an expert on food substitutions to help others navigating the nutritional, emotional, and social aspects of dietary restrictions. 


In 2021, I started working with pregnant women, new parents, infants and children on basic nutrition. In 2022, I became a Certified Lactation Consultant and now have the ability to work through the concerns parents have while breastfeeding. 

As an RD, I've enjoyed teaching cooking classes for up-and-coming dietitians with accommodations for dietary restrictions as the primary focus. I've also found reward in counseling clients with alternative eating patterns on getting sufficient macro- and micro-nutrients into their diets. For those caretakers or event organizers who struggle to accommodate the "gluten-free, vegan, peanut allergy" person, I've coached you, too. 

I encourage you to make an appointment if you have any of the dietary restrictions to the left or may need to implement one or accommodate someone else's soon. 

We can help with: 

  • identifying trigger foods 

  • menu planning 

  • targeting vitamins and minerals you may be deficient in

  • understanding nutrition labels 

  • tips for "picky" or selective eaters

  • introducing allergenic foods to infants

  • breastfeeding support

  • weight management

  • heart health

With guidance from a Dietitian, anyone can learn to balance a healthy lifestyle with the pleasure of food. Food is the zest of life!
