Jenny Ryoo

Cert. CN / Canine and Feline Nutrition Consultant

When working with clients, my top priority is to create a diet plan that works well for both the animal and the owner. Each recipe should be a perfect fit for the family, nutritionally and practically. Choosing a nutritionist is a personal decision – if you have any questions about if I am the right fit for you and your animals, please reach out. I’m happy to chat!

I was recommend by a friend to use Jenny and I was not disappointed. My Shepherd has many food allergies and Jenny worked with those limitations and created an affordable and fun to make, recipe. Not only did she include the recipe, she included step by step procedures, helpful hints, and educational documents that allowed me to learn and understand rather then just make the recipe. I will ABSOLUTELY work with Jenny again!

I hired Jenny to formulate a recipe for my three years old Golden retriever and I am really happy with the service. Jenny was super easy to work with, she made sure I have access to the ingredients easily and acted promptly when changes were needed. Excellent communication and quick the turnaround time. I would highly recommend Jenny to anyone who's looking for customized and properly balanced meals!
