Hobbies: Spending time with family and friends. Running and lifting weights.  Reading in and outside of book club. Traveling. Helping with home projects.

Hobbies: Spending time in nature- walks, hiking, skiing, running. Traveling. Reading

Favorite Food: I love Root Farmacy :) . I'm gluten and dairy free- so always looking for healthy substitutions. I love any wild caught salmon dishes, pan sheet veggie recipes, crockpot meals when the weather gets cooler. My heritage is Polish- so dill pickle soup is a delicious staple at our house. 

Favorite thing about working at Root: There are so many things I love about working at Root, that I can't just pick one. At the top of my list- The people I work with, the collegial atmosphere, the common goal of delivering food as medicine to our community and beyond, and of course helping clients recover from years of chronic symptoms with the food as medicine approach.

Working with Dr. Marzena Slater and Amy Masterson has been the most rewarding health experience. Within a month I saw a dramatic reduction in my symptoms and over time they continue to improve.
