Kassy Montgomery, RDN, CDCES

Functional Medicine Nutritionist, Registered Dietitian & Diabetes Educator
Verified by Integrative Health Connect

Kassy Montgomery is a Registered Dietitian who has been practicing since 2017. She earned her Bachelor's Degree in Health Sciences, with a specialty in Nutrition, at Keene State College in New Hampshire and completed her dietetic internship through Oregon State University.

She found her calling as a dietitian through her love of running and endurance sports. Her goal is to help each patient feel their best so that they can enjoy life and be there for the ones they love most.

Kassy’s favorite part about being a dietitian is combining the power of the “food as medicine” approach with delicious flavors and convenient cooking strategies. There is beauty in taking something that can feel overwhelming and impossible, like managing a chronic disease, and making it not only achievable but enjoyable.

Her clinical specialties include diabetes education and weight management. She holds a certificate in diabetes care and education and has worked for the past 5 years at a diabetes and endocrine clinic. She completed a 75-hour training for weight management in both adults and pediatrics. Her specialties include caring for patients with type 1 and 2 diabetes, insulin resistance, PCOS, hyperlipidemia, NAFLD, and thyroid disorders. She has extensive experience with continuous glucose monitors and insulin pumps and is an Omnipod and T-slim Certified Insulin Pump Trainer.

In addition to her training in nutrition, Kassy holds a 200-hour yoga teaching certificate from Sadhana Yoga School in New Hampshire and a 300-hour teaching certificate from The Yoga Space here in Portland. She has seen the benefits of movement and mindfulness firsthand, and aims to include these practices in her lifestyle recommendations for all patients.

Kassy believes that every individual has the power to heal their body, and she is here to help you with an individualized nutrition and lifestyle plan that works for you! No more yo-yo diets! In fact, no more diets at all. She will use her creativity and down-to-earth approach to help you make diet and lifestyle changes that last. Kassy is a friendly face and sets a welcoming atmosphere for you to work together to create the life and health that you deserve.
