Rediscover What It Means to Feel Good

We understand how frustrating it is to live with chronic symptoms that don’t seem to go away – fatigue, inflammation, brain fog, digestive problems, pain, or hormonal imbalances. Traditional medicine often masks these symptoms with medication, but it doesn’t always address what’s actually causing them.

At Dr. Harrison’s Center of Functional Medicine, our mission is to help you heal from within using a proven, personalized, and natural approach.

Whether you’re dealing with autoimmune conditions, thyroid disorders, chronic fatigue, or digestive issues, our functional medicine programs are designed to identify and correct the underlying imbalances that are keeping you from feeling your best.

Functional Medicine: A Better Model for Chronic Conditions

Most chronic conditions, including thyroid issues, autoimmune disease, depression, cardiovascular problems, and chronic pain, are not isolated problems. They are usually the result of systemic imbalances involving your immune system, hormones, gut, or metabolism.
Functional medicine works to restore these systems through:

Comprehensive lab testing
Root-cause diagnostics
Anti-inflammatory diets
Nutritional supplementation
Stress and sleep optimization
Detoxification and gut repair
Thyroid and hormonal support

When your body is given the right tools, it knows how to heal. Our goal is to support your body’s natural healing mechanisms so you can live with vitality, energy, and confidence again. If you’re searching for a trusted natural doctor in Denver, know that we’re here to guide you on your healing journey, every step of the way.

What Dr.Harrison has done for our little girl is nothing short of a miracle. We had been following protocol given to us by our traditional medical pediatrician for two years after her initial Celiac disease diagnosis, but had seen no improvement in her symptoms, and multiple and increasingly worrisome new symptoms throughout. We were advised to put her on medications that she would have take for the remainder of her life, and at the young age of 11, we weren’t willing to sentence her to the multiple negative side effects that she’d have to deal with. We were looking for healing, not the masking of her symptoms. Our search for an alternative approach to addressing the root cause of her symptoms led us serendipitously to the doorstep of Dr. Harrison. After completing a thorough and in depth exam with labs, we discovered that our girl had also developed all the markers for Juvenile Rheumatoid arthritis. So we now knew that we were dealing with not just one, but two autoimmune disorders. From the minute we made contact, Dr. Harrison listened genuinely to our concerns, and together, we formulated a treatment plan that would relieve our daughter of her constant pain and suffering. His approach was refreshingly thorough, insightful, and consistent with what we had hoped for her healing journey. His friendly and caring approach made all the difference when we were trouble shooting various aspects of our daughters illnesses, and in many ways, we feel we have gained an incredible ally and friend. Now that we’re approaching the completion of her course of treatment, I can confidently say that our daughter is no longer a prisoner to her pain and suffering. She is returning to the active lifestyle she once knew and loved, and where once sat a depressed, exhausted and sedate 11 year old little girl, now stands an eager, energetic and outgoing gymnast who is currently rebuilding her stamina and physique in order to participate in her beloved sport of competitive tumbling. Dr. Harrison saved our daughter from a lifetime of nasty pharmaceuticals and side effects, and brought us to a place of true healing and joy we had never thought possible. Our daughter is living proof that Dr. Harrison is an extremely effective and yet, humble, healer whose knowledge and expertise will change lives. Our only hope is that someday, Dr. Harrison’s healing approach and continued research will flood the masses of traditional medicine, and change it from one of masking symptoms, to one of true healing and vitality. Thank you, Dr. Harrison, for saving our little girl. There are no words to adequately express how deep our gratitude goes for your time, your knowledge, devotion, and love for humanity.

I found Dr. Harrison when I was at a very low point in my life dealing with unexplained neurological symptoms. I couldn't get timely appointments with allopathic doctors, and Dr. Harrison's compassion and empathy truly got me through those times– He goes above and beyond, and genuinely cares about helping you. After 4 months of working with him, my symptoms are mostly gone and we've ruled out the scary diseases. I feel better than I ever have in my life: more energy and no mid day crashes, falling and staying asleep and waking up easily in the morning, and getting sick less frequently. I feel confident I now have the tools to keep my symptoms from flaring again and staying healthy from here on out. I can't thank Dr. Harrison enough!

I had been suffering with digestive issues for over a decade and adrenal fatigue for maybe half that time. Constant searching for symptoms/solutions online and a vicious cycle of ups and downs really had me in a sad and depressed state. Dr Harrison has truly changed my life. His approach is kind, thoughtful and thorough. I now have the answers I was looking for as well as the tools to navigate life. Thank you so much for helping me ??

I have completed Phase 2 out of 3 of Dr. Harrison’s clinical workup, and my experience has been outstanding. Dr. Harrison is the only doctor who has given me hope for resolving my inflammatory skin condition without relying constantly on medication. From the initial discovery call to the physical examination, his compassion, expertise, and professionalism have been evident throughout. I am eager to return to his practice as soon as I have the finances to continue. I feel reassured that I am in good hands with Dr. Harrison

Frequently Asked Questions About Natural Doctors in Denver

What is a natural doctor, and how is it different from a traditional MD?

A natural doctor typically uses a functional or holistic approach to diagnose and treat health issues. Instead of just managing symptoms with pharmaceuticals, we look for the root cause and use natural therapies like nutrition, lifestyle changes, herbal support, and supplements to help the body heal itself. Our care often complements that of your primary physician and can reduce your reliance on medications over time.

Can a natural doctor help with thyroid problems?

Absolutely. Thyroid conditions, especially Hashimoto’s and hypothyroidism, are often poorly understood in conventional medicine. Many patients are told their thyroid is “fine” even though they still feel exhausted, foggy, or depressed. At our clinic, we go beyond standard TSH testing and look at a full thyroid panel, inflammation markers, adrenal stress, gut health, and nutrient deficiencies to get a full picture of what’s really happening – and then treat it naturally.

What kind of testing do you use?

We use advanced lab testing tailored to your specific symptoms. This might include hormone panels, thyroid function testing, food sensitivity testing, gut microbiome analysis, nutrient deficiencies, inflammatory markers, and more. These tests help us find what’s out of balance so we can correct it.

Do I have to live in Denver to work with you?

No! While we are based in Denver, our telehealth consultations allow us to work with patients across Colorado and beyond. Many of our clients don’t even need to step foot in our clinic – and still get life-changing results.

Do you accept insurance?

We do not bill insurance directly, as our model of care is comprehensive, customized, and often outside the scope of traditional insurance coverage. However, we can provide you with a superbill you can submit to your insurer for potential reimbursement, depending on your plan. Give us a call for more information, our friendly team can guide you on the best options for you.

What conditions can a natural doctor help treat?

A natural doctor in Denver can help address a wide range of chronic and acute conditions, including digestive issues, autoimmune disorders, hormonal imbalances, chronic fatigue, migraines, cardiovascular problems, and more. Rather than simply masking symptoms, natural doctors focus on identifying and addressing the root causes of illness using holistic, evidence-based approaches like lifestyle modification, nutritional therapy, and targeted supplementation.

Is seeing a natural doctor safe for children or seniors?

Absolutely. Our qualified natural doctor in Denver can provide safe, personalized care for individuals of all ages, including children and seniors. Treatments are non-invasive, gentle, and customized to suit each patient’s age, medical history, and specific health concerns. Whether you’re seeking to boost immunity in a child or improve vitality in older adults, our holistic approach supports wellness at every stage of life.
