MY APPROACH
It’s possible to have a lifestyle based on GI comfort instead of distress, and my sole purpose is to help you restore your gut health through education, not judgment.
Based on your lifestyle, my goal is to help you develop realistic dietary strategies tailored to your specific digestive disorder.
I’m as much a teacher, facilitator, and strategist as I am a registered dietitian, and with my leadership, you can learn which foods help, which hurt, and how you can manage the difference.

Hi, I’m Mallory Grassmuck,
MS, RD, LD
It’s been twelve years since I shifted my professional focus from that of a general-practice dietitian to one who specializes in digestive disorders. Yet, only recently – when my husband and I were at the dining room table helping our young sons with a jigsaw puzzle – I recognized the similarity between what I was doing as a parent and what I do as a healthcare provider.
Like a jigsaw puzzle, every patient has a digestive framework, but sometimes their individual pieces don’t fit together the way they should. Puzzles are based on the idea that there’s always a solution, and by working together we CAN piece your health back together again!
WHAT’S POSSIBLE CHECKLIST
- It’s possible to stop researching restroom logistics and locations prior to visiting public spaces.
- It’s possible to eat in restaurants and not regret it later.
- It’s possible to free up trunk space by removing your emergency wardrobe change.
- It’s possible to travel without the fear you won’t make it to the next roadside rest or wait in line on a flight.
- It’s possible to make (and keep) commitments without canceling at the last minute.
- It’s possible to be confident while grocery shopping and packing meals to eat at work or school.
