Tina Patnode, RDN, LD

Registered Dietitian Nutritionist Specializing in Digestive Health


Tina Patnode is a Registered Dietitian Nutritionist (RDN) with 23 years of experience in Medical Nutrition Therapy. She has a huge interest in the human microbiome (aka: microorganisms residing in the gastrointestinal tract). For several years, Tina worked in four gastroenterology clinics in Portland, Oregon where she gained exceptional clinical experience . She thoroughly enjoys helping individuals with digestive disease and conditions improve their quality of life using diet and nutrition therapy.

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 virtual nutrition therapy (Telehealth) to those who reside in Oregon, California, Arizona, and Colorado. Washington State certification is in process!

Over ten years ago, Tina started to educate her clients on the low FODMAP diet. The low FODMAP diet was developed by The Monash University and has a wealth of evidence-based research to support its effectiveness in minimizing digestive symptoms in those who have irritable bowel syndrome. Tina is honored to have been trained by well-known, respected industry professionals Kate Scarlata, RD, and Patsy Catsos, RD.

Tina recognizes that each person is unique and has specific needs. She will develop a diet and nutritional plan that is tailored to get you on track to optimal digestive health.

Tina firmly believes that to be successful, you need more than a list of what not to eat; you need to know what you can eat. With the support and guidance of a well-versed and knowledgeable dietitian like Tina, the success-rate of diet and nutrition therapy is vastly increased.

Outside of Tina’s professional life, she stays active and enjoys walking, cycling, and Bikram yoga.
