Favorite thing about working at Root: Practicing at Root allows me to truly get to know each person, put the puzzle of symptoms together and then create a solution as a team (Root member/Physician/Dietitian). This is how I always imagined I would practice medicine. Plus, I get to work with an awesome team and talk about food all day!


Marzena Slater
MD, IFMCP
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.

Favorite food(s): Right now, I'm loving homemade pasta with a simple from scratch tomato sauce. My favorite foods tend to rotate quite a bit but simple foods with quality ingredients are always what I go for.
Favorite thing about working at Root: The people! So many fun personalities and everyone is just full of energy. It makes days go by very quickly.
