About

Nila is truly passionate about using food to modify the gut microbiome, and improve health.  She believes that everyone with IBD should be encouraged and supported to incorporate nutritional therapy (in its many individualized forms) into their treatment plan.

Nila Williamson, MPH, RDN, CD

Nila Williamson is a Registered Dietitian Nutritionist specializing in inflammatory bowel disease and intestinal failure.   

Nila has 15+ years experience working as a pediatric dietitian in primary care and with the gastroenterology division at Seattle Children's Hospital.  She was a dietitian with both the IBD and intestinal rehabilitation programs, supporting the nutrition of complex patients  struggling with severe disease and intestinal surgeries.  Nila has worked with children, adolescents, and adults of all ages with IBD to implement nutritional therapy.  She has experience working with clients using:

  • Exclusive Enteral Nutrition (EEN)

  • Partial Enteral Nutrition (PEN)

  • The Specific Carbohydrate Diet (SCD)

  • The modified Specific Carbohydrate Diet (mSCD)

  • Crohn's Disease Exclusive Diet (CDED)

  • Anti-inflammatory Diet for IBD (IBD-AID)

  • Autoimmune Protocol Diet (AIP)

Nila lives in Olympia, Washington with her husband, two young children, and the sweetest dog there ever was.  As her family grew she had to say goodbye to her clinical position and 60 mile commute to work.  She now works part-time in pediatric primary care and started this practice because she missed having daily poop conversations.  Well actually not really...because she still has those with her 5 year old.
