“The ladies at Functional Nutrition Resources are absolutely amazing! Each one has been so understanding and helpful in my journey. In just 8 short weeks I am starting to get my life back.

I have already been able to reduce medication, reduce my stress, significantly decrease my anxiety, lose weight, decrease blood sugar, and am on the road to a healthier life! I can't wait for the next phase! Get started with this group today...you won't be disappointed!!!”

- Jill Spreiter

“I didn’t get healthy until I was 73 years old. I pretty much had hit bottom when the traditional medicine system was not helping me. The joint and back pain was so horrible that it was unbearable to even make my bed. I was seeing a pain management specialist but after two unsuccessful injections in my back, I finally took responsibility for myself and found Functional Nutrition Resources. The support system is phenomenal and they will get to the root cause and provide a step-by-step process to fix your problems. Fast forward 1 ½ years later, I’m off multiple drug prescriptions, pain-free and I’ve lost 35 pounds.”

- Becky Hopper- IT WORKS! IT WORKS!

“I spent a decade dealing with stomach, gut, and sleep issues. It negatively affected every part of my life. I’ve been in the program for about two months and the quality of my life has drastically improved. I no longer have the issues with my stomach and gut that I experienced before. I am sleeping so much better. I have more energy and I have even lost about 15 pounds. The staff is extremely knowledgeable and helpful. Functional Nutrition Resources is one of the best things that’s ever happened to me. I highly recommend!”

- Dustin Morrow

Our Core Values Of Care

An Integrative Approach

Unlike conventional medical care, we help practice members heal and transform their health naturally while empowering them with the tools, resources and knowledge to avoid many of the pitfalls that created their illness in the first place. No matter where you are right now... with our expert guidance you can heal and lead a vibrant life! Guided step-by-step by our team, you will implement an integrative approach to your wellness, drawing from the most up-to-date nutritional science and lifestyle medicine, to significantly improve your health and alleviate symptoms.

Dedicated Attention

In your typical 7-minute doctor's visit, there is little time to understand the depth of your illness... let alone the contributing factors that may have caused it.

During your in-depth intake evaluation, we take the time needed, one-on-one, to conduct a thorough review to understand all the potential triggers for your illness. This review includes your past medical and health history, assessment of your past and current symptoms, your past and present nutrition, environment, stress levels and gut health. Your in-depth health history is the start to unraveling the root causes of your illness.

Personalized Care

Not only is each practice member biologically unique, but their illness is unique too. There are so many factors that may be to blame for your illness – from lifestyle choices, food choices, allergies and even toxins in your immediate environment... plus let's not forget mindset (which plays a big role of your health).

After we do your evaluation, we may conduct further specialty lab tests (that your current doctor may not even know about). Plus, we use other assessment tools to uncover the origin of your health issues. With this knowledge we will recommend your unique whole body healing plan.

Innovative Healing Protocols

Did you know that it takes on average 17 years for clinical breakthroughs to make their way into your conventional doctor's office? That means many health care practitioners are dispensing outdated advice and not using the best lab testing available for your case. Chances are they are not even aware of the proper testing that could make all the difference in your healing plan.

At Functional Nutrition Resources, we are trained in up-to-date functional medicine – including the best, most advanced testing and we pair that with current nutritional science so that you can finally achieve your health goals .

Root Cause Resolution

Unlike conventionally-trained doctors, our care team always focuses on getting to the root causes of your illness. We also examine the key cellular imbalances that are responsible for virtually all symptoms you’re experiencing right now.

Also known as functional medicine, our care is so effective because we focus on dealing with the "up-stream" catalyst of chronic illnesses – including toxicity in your home or work-place, potential food intolerances and allergies, gut & hormonal imbalances, along with mindset issues that all determine how healthy you are to date.

Co-Creating Health

Changing your lifestyle may seem daunting, but we teach you how to use mindset tools to overcome stubborn habits that aren't serving you any longer. We make the prospect of getting healthy "fun" and have a wide range of tools in place to support you during your health transformation and beyond.

We also leverage health coaching and other forms of support and accountability so your new healing lifestyle practices can become an integral part of your everyday life. We also harness the support of virtual communities to give you support remotely, as you make important changes that translate into lasting health.
