What originally sparked your interest in nutrition or made you want to become a dietitian?
In college, my original major was Biological Sciences. My goal was to go to medical school to become a pediatrician. After realizing the responsibilities a doctor had, I chose another profession in which would allow me to have a family and a career. Nutrition was important to me as I had always struggled with weight. I wanted to understand how food affects weight and how to help myself along with studying many diseases affecting others, ie diabetes.

I enjoy watching my daughters play sports and baking.

About Me:

What is your favorite food?
I love and am fascinated by mushrooms! Mushrooms have such a unique umami flavor among vegetables and can also offer a wide variety of flavors depending on the type of mushroom. Plus, their appearance is so beautiful and they can even synthesize Vitamin D just like humans! I always pick the mushroom appetizer or entrée at a restaurant especially if it uses harder to find varietals like oyster or trumpet mushrooms. I have gone on expert lead foraging trips and always pick up unique varietals like hen of the woods when offered for sale at the market. Lastly, no holiday at my house is complete without including some special occasion mushrooms like morels or chanterelles!

What is a good way to make sure that you are eating healthy?
Meal Planning is an often overlooked tool to ensure healthy habits. While taking time each week to sit and plan out meals for the week can seem time-consuming, meal planning allows us to be proactive about our food choices rather than just reacting to the immediate environment each night at dinner time. Meal Planning allows us to envision how we can incorporate our dietary goals into our lives, such as eating more omega-3 rich fish or more leafy greens. A meal plan can be as flexible or as thorough as makes sense for your lifestyle; you can earmark recipes for different days or just designate themes such as Friday is Fish night.

What do you enjoy doing outside of work?
I enjoy reading all types of fiction, hiking, and trying out recipes from my ever-expanding cookbook collection.
