About Jessica Doyle, CNTP, RN

Jessica Doyle is a Certified Nutritional Therapy Practitioner (CNTP) and Registered Nurse (RN). She is also a certified health coach for preconception, pregnancy and postpartum. With over 20 years working in the healthcare industry, Jessica specializes in supporting her patients through tailored nutrition with the goal of experiencing more vitality, wellness and energy.

After ten years working as a labor and delivery nurse, along with experiencing her own health issues, she realized traditional western models of medicine couldn’t provide the solutions most people needed to resolve their health issues. She realized that some patients felt dismissed and frustrated with “normal” test results despite abnormal symptoms, which persisted and often developed into more serious health concerns.

Always a learner and never satisfied with the status quo, Jessica decided to explore other avenues of healthcare and found Functional Medicine. Functional Medicine combats the idea of medicine-centered treatment and shifts the focus to the whole patient. She now helps patients heal by addressing the root cause of illness through personalized nutrition and lifestyle modifications. Read more →

Success Stories


Jessica is incredibly knowledgeable about different diets for hormones and IBS. She got me on a nutrition plan that helped immensely with my bloating and cycles. She was also really reasonable with her expectations. I'm a working mom and needed something achievable. She totally gets that, and made sure that our goals felt sustainable and achievable. — Kristie P.
I have been seeing Jessica Doyle who is amazing!!! She has stabilized my blood sugars and I've lost weight! She's amazing and I'm assuming you are just as amazing for bringing her on board! — Colleen W.
Jessica has been hugely helpful in assisting me with nutrition in preconception, and now during IVF. She obviously gets the nutrition piece, but she also used to be a L&D nurse so I feel like she really gets the preconception/pregnancy pieces as well. Anyways, thanks for doing what you do, and for helping me on this path! Excited to have you as a resource during pregnancy as well! — Lara Y.

Frequently Asked Questions

A nutrition consult helps us achieve an in-depth review of your symptoms and history to see where issues began. It's a look into your everyday lifestyle and foods to see where we can make adjustments to better meet your goals. In the end, you'll have a personalized plan to support optimal nourishment while addressing any imbalances or dysfunction. And during follow ups, we'll make sure the plan is working for you and make adjustments to be sure it’s sustainable for long term health.

This is NOT for you if you want a superficial, one-size-fits-all meal plan. We won't recommend a bunch of commercially produced meal replacements bars or powders. And there is no shaming for going off your plan. We do NOT view cravings as “low will power” but rather as a tool to better understand your body.

Jessica Doyle, CNTP, RN enjoys consulting one-on-one with patients on fertility, pregnancy, gut health, autoimmunity and metabolic conditions (PCOS, diabetes, high cholesterol, etc). She also provides nutritional education for weight loss, anti-aging, aesthetics and sports performance.

As a Certified Nutritional Therapy Practitioner and Registered Nurse, Jessica helps her clients figure out their unique nutritional needs while transforming everyday food into medicine.

She utilizes a science end evidence based nutrition approach which takes into account your health goals, health history, and food preferences while using functional nutrition tools to uncover things like food sensitivities, digestive health issues, and genetic variations which directly impact nutrient levels and your current state of health.

By taking this whole-person approach, she’s able to craft a custom and practical nutrition plan that not only makes clients feel great in body and mind, but creates the ideal conditions for healing chronic disease and creating long-term health.

No extreme dieting. No arbitrary one-size-fits-all way of eating. No weird meal replacement snack or bars to buy. Just a clear path to a nourishing, fulfilling, and healing relationship with the real foods your body (truly) craves.
If you are working with Dr. Maren she will order comprehensive labs. If you are seeing our nutritionist only, she can order food sensitivity testing and refer you to nutrigenomics testing. However, other labs must be ordered through your physician. You can share those labs with Jessica so that she can use them to help guide your nutrition plan.

Yes! If you would like to share recent labs with us, please upload them to your online chart under the 'Labs & Documents' tab of the portal. Click on the pink button "UPLOAD NEW DOCUMENT." Please upload relevant labs as a single report vs one page at a time. If you are doing this from home, you can utilize an app like TurboScan to create a multiple page PDF and upload that directly from your computer. You may also fax them to (303) 351-1100. Please do not mail hard copies to the office.

If you are interested in a more customized plan for supplements, testing and nutrition, we highly recommend the Nutrition Genome DNA Kit. This report looks at nutrigenomics, which is the study of how foods affect our genes, and how genetic differences affect the way we respond to food. You can order this test yourself here and review results in detail with our nutritionist during a nutrition consult. Be aware that results often take 5-6 weeks.

Yes! For almost everyone, supplements are an important aspect of the treatment plan. We will work together to develop a clear and specific supplement plan based on your unique needs - with consideration given to digestion/absorption, nutrigenomics, micronutrient deficiencies, etc.

Which means: we'll tell you exactly which vitamins or supplements you need (or don't need).

You'll have discounted access to prescription quality supplements through FullScript, Xymogen and others. We only recommend personally vetted companies with the highest quality standards and 3rd party testing.

Jessica Doyle sees clients worldwide. All of our visits are scheduled virtually via telehealth. Our office is very familiar with virtual consultations and we've been working with patients remotely for over 4 years (way before telehealth became a thing with Covid-19).

Our practice was built to facilitate virtual consultations, and connecting with patients remotely is easy. There’s no need for fancy software on your end, as long as you're comfortable with using the internet and communicating online.
