Hi, I’m Stephanie Dillingham.  I’m a private practice Registered Dietitian Nutritionist (RDN) located in Lafayette, Colorado.  At Thee Square Nutrition, I offer one-on-one nutrition counseling that will help you meet your specific health goals.   I provide personalized nutrition care that takes into consideration your medical history, lifestyle, and food and cooking preferences to create an evidence-based plan that will improve your health and well-being.

I have experience counseling patients with diverse needs and specialize in counseling patients with celiac disease, gluten intolerance, and food allergies.  Fifteen years ago, I was diagnosed with celiac disease and have maintained a gluten-free diet since that time and am also the mother of a teenager with celiac disease. Changing your diet to meet your health goals is hard! I know first hand what it is like and am passionate about helping you and your loved ones navigate the many issues you might encounter.  For more information on what conditions I treat and what it’s like to work with me see my Patient Information page.

My interest in nutrition started when I had my first child and he was diagnosed with multiple food allergies at the same time that I was diagnosed with celiac disease. Suddenly, we were having to eat a very restrictive diet, and I worried that my child might not be getting the nutrition he needed. I struggled with meal planning around our dietary needs and worried about feeding us safely while eating out. Eventually, I enrolled in a nutrition class that I loved, and decided to go back to school to become a dietitian. I’ve lived in Boulder county for nearly 20 years (both Lafayette and Louisville) and spend my free time with my husband, two teens, and two labradoodles. I enjoy hiking our beautiful trails, doing yoga, cooking, reading and traveling when I get the chance.

Professional History and Qualifications

Prior to opening Three Square Nutrition I worked at Boulder County Public Health as a member of the Child Health Promotion team. As part of this team, I helped with the Farm to Early Care and Education nutrition education program, Healthy Eating Active Living program, and Breastfeeding Friendly Child Care program. I taught childcare professionals the basics of healthy eating in childhood, how to create more nutritious child care menus, how to manage food allergies in a child care setting, and how to support breastfeeding mothers.  Along with my RDN credentials I am a Certified Lactation Counselor (CLC).  Previously, I completed a 1000-hour internship where I worked in dietetics at Avista Adventist Hospital, Boulder Valley School District and Boulder County Public Health.  Before having children and becoming a dietitian, I completed a degree in Industrial Engineer and Management and worked as a software developer.





What People are Saying

Stephanie was both thorough and efficient, and I found her extremely knowledgeable. She busted some myths, and as it turns out, there were many opportunities to improve my and my family's diet to achieve balances in protein, B12, zinc and Omega 3s. I'm grateful for Stephanie's insights, and as I told her, everyone should go through this process. It was an invaluable exercise!
Stephanie is one of the most knowledgeable and professional Registered Dietitian Nutritionists I have ever encountered. Not only is she highly educated with a Master’s Degree, she is extremely personable and will put you at ease with whatever concerns you may have. While too many health care providers are quick to prescribe a plan with little patient input, she takes your desires into consideration and will ensure she puts together a plan that works for YOU and YOUR goals, while also providing education, counseling, and guidance along the way. If you are looking to make healthier changes or have other health concerns, rest assured that you will be in great hands with Stephanie and her dietary advice! Do not hesitate to call her!
