Food & Allergy

Discover the root cause of disease,
Replenish deficiencies,
Remove toxins and
Balance all systems in the body using Nutrition Response Testing!

My name is Siera Marshall.  
My purpose is to provide you with the missing piece necessary to improve your quality of life by using Functional Medicine to restore and maintain optimal body functions.
I will locate underlying sources of symptoms and eliminate toxic barriers to healing in order to support the body's natural healing processes.
After discovering the root cause of symptoms and disease, I will provide organically grown, whole-food supplements for healing; these supplements can be a better option to avoid common side effects caused by prescribing potentially dangerous prescription medications to mask the symptoms caused by deficiencies, toxins, malnutrition or organ dysfunction.
This program is designed to naturally support the body by using food as medicine, movement as a form of therapy, mental health support, lifestyle changes and more!

"Let food be thy medicine and let medicine be thy food" -Hippocrates 


I offer a complimentary consultation visit virtually or in office before testing for more information and to answer any questions you may have regarding the program. This visit is to sit down with you to talk about your case and provide information about how I can help you using Functional Medicine and Diagnostic Nutrition Response Testing.

Diagnostic Testing

Diagnostic Nutrition Response Testing is a noninvasive system of analyzing the body to determine underlying causes of illness and non-optimal health.

Heart Rate Variability Testing

The Heart Rate Variability Testing allows me to test the functionality of your Nervous System which gives me information about your energy, sleep quality, stress response, ability to adapt as well as the physiological age of your body according to your nervous system function.

Report of Findings

This visit is scheduled after initial testing. This is where I will present your specialized Wellness Program to you and we will go over the results of testing, prepare goals and structure your program to your specific needs, goals, financial ability and discuss supplementation or minor lifestyle changes.

Weight Loss Evaluations

Did you know that weight loss is more than just diet and exercise?
One or multiple of these tests could be helpful in identifying why you are not losing weight:

1. Testing for digestive enzyme levels: If you do not have the enzymes necessary to break down the food you are eating, this can lead to those nutrients being stored as fat and not broken down and absorbed into the body. If you have tried everything, this is a great place to start!

2. Testing for food sensitivities: if you are sensitive to a food you are eating, this leads to increased inflammation in the body and the inability to digest those nutrients; as well as experiencing bloating, brain fog, back pain, digestive upset and more! Inflammation disrupts your body's ability to heal!

3. Testing the Central Nervous System: You have two states of being: "Rest & Digest" or "Fight or Flight". If your nervous system is in a state of Fight or Flight, you are NOT digesting your food! This means that those nutrients sit in your gut for too long, causing an increase in fat mass. This test evaluates your stress response, ability to rest, sleep quality, physical fitness score and ability to respond to environmental changes.

4. Test hormone levels: Hormone imbalance is a common factor for people who struggle to lose weight. Your hormones play a huge role in regulating your metabolism. A sluggish metabolism could be another reason for weight gain.

5. Test for environmental toxins: Evaluating the toxic burden on your body is important to your overall functioning. Common toxins are found in specific foods, cookware, containers, gardening soil, cars, skincare, make up, medications, and so much more! The more toxins you have in your body, the harder it is for your organs and systems to function optimally.

 6. Gut microbiome testing: The fungus and bacteria in your gut microbiome are considered your second brain because of its communication to your body and organs. Your gut microbiome effects your mood, sleep, energy, irritability, weight gain, skin conditions (acne/rashes), etc.

Using Functional Medicine, your practitioner can order a Full Body Diagnostic Test in order to ultimately replenish nutritional deficiencies, regulate hormone levels, remove toxins, replace enzyme levels, regulate the gut microbiome,  restore normal nervous system function, and optimize organ function.
