Mariah Ecker, RD
Fear not, food can be your friend! As someone who used to overly stress about food choices, I love supporting clients in forming a healthier relationship to their food and body. Life is stressful enough, and food should not be contributing to that!
As a Monash certified FODMAP dietitian, it's my passion to help individuals with gastroenterology issues improve their symptoms on the least restrictive diet possible. Food anxiety and restriction doesn't have to be your forever, and it likely isn't helping your gut either!
And while IBS, IBD, and gut health are "my jam", I also enjoy supporting women who struggle with weight loss and PCOS. I'm a huge nutrition science nerd! Let me help you untangle the fads from the facts.
Special Interests:
Gastroenterology, sustainable weight loss and PCOS, aerial silks, and backpacking

Nicole Sievers, RD CDCES
I love food and I love to eat!
Being both a CDCES and a person actually living with diabetes gives me a unique perspective. I've tried everything there is to try and can share my successes (and more entertainingly my mistakes!) to help guide you on your path to wellness.
My patients often thank me for making complicated information easy to digest. I truly enjoy teaching and take great pride in helping things finally make sense.
My secret power is data. It's not sexy but it can open up a whole new world where difficult becomes easy. From diabetes devices to nutrigenomic testing, let me make data and technology work FOR YOU!
Special Interests:
Diabetes technology, nutrigenomics, DIY projects, and all things dog related

Julia Solomon, RD
I’m a passionate foodie!
My love for cooking and baking (and eating!) started at a young age. The connection between food and health began to spark my interest and I knew I wanted to study nutrition.
I worked for UCSF Health for seven years before relocating to Kauai. I reside in Kalaheo with my partner and our new baby boy. When not working as a dietitian I enjoy traveling with my ohana and trying new foods. You can find me shopping at the local farmers’ markets several days a week.
I am very excited to be a part of the Hawai’i Nutrition Hui. I look forward to working with you to help achieve your health goals while learning to love and appreciate food!
