Tina Patnode, RDN, LD

Certified Gastroenterology Nutritionist


Tina Patnode is a Registered Dietitian Nutritionist (RDN) with greater than 25 years of experience providing Medical Nutrition Therapy (MNT) for individuals with gastrointestinal conditions such as Irritable Bowel Syndrome (IBS), Inflammatory Bowel Disease (IBD), Small Intestinal Bacterial Overgrowth (SIBO), Celiac disease, and Gastroparesis.

Tina also works with those individuals who have not received a definitive diagnosis but suffer from nausea, vomiting, loss of appetite, acid reflux, abdominal bloating, abdominal pain, diarrhea, and constipation.

For several years, Tina worked as a GI Dietitian for a Gastroenterology Clinic in Portland, Oregon where she was able to broaden her expertise.

Tina has always had a dream to start her own private practice. So, that is exactly what she did! In 2018, Tina founded GI Nutrition NW, LLC and opened her office in Southwest Portland. In March of 2020, Tina began providing Telehealth to those who reside in Oregon, Washington, California, Arizona, and Colorado.

Outside of her thriving private practice, Tina is advancing her practice as an Integrative and Functional Nutrition Certified Practitioner applying a food as medicine approach to optimizing digestive health.  She is evidenced-based but not evidence-limited and will devise an individualized plan of care to meet the unique needs of her clients.
