Dr. Glenn Harrison is a functional medicine doctor based in Westminster, Colorado (Denver metro area). He holds a Doctorate in Chiropractic Medicine from Northwestern Health Sciences University in Minnesota and a Bachelor of Science degree from the University of Manitoba in Canada.

His extensive post-graduate training covers functional neurology, functional endocrinology, functional blood chemistry, and clinical nutrition. With over a decade of experience focusing exclusively on chronic and autoimmune conditions, Dr. Harrison has helped patients from across the country and around the world regain their health.

Dr. Harrison's journey into functional medicine is deeply personal. While working as a laborer in a remote mining community in Canada, he suffered a severe back injury at age 19. After months of pain and failed conventional treatments, a single chiropractic visit changed everything and inspired him to pursue healthcare.

During chiropractic school, he was diagnosed first as prediabetic and then as a type II diabetic — a result of chronic stress and poor self-care. An internship with a functional medicine practitioner helped him reverse his own condition and showed him the power of root-cause medicine. That experience became his mission: helping others overcome chronic illness the same way he did.

Dr. Harrison's Center of Functional Medicine is located at 9035 Wadsworth Pkwy #3300, Westminster, CO 80021 — conveniently situated in the Denver metro area. The office is open Monday through Thursday, 9am to 5pm.

Functional medicine is a science-based approach to healthcare that focuses on identifying and correcting the root causes of disease rather than just managing symptoms with medications. While conventional medicine often asks "What disease do you have and what drug treats it?", functional medicine asks "Why are you sick in the first place and how do we fix the underlying problem?"

At Dr. Harrison's practice, this means comprehensive lab testing, detailed health histories, and personalized care plans that address your unique biochemistry — not a one-size-fits-all approach.

Dr. Harrison's approach is built around six foundational pillars of health:

• Physical Fitness — movement and exercise tailored to your condition
• Nervous System Balance — optimizing brain and nerve function
• Detoxification — supporting your body's ability to eliminate toxins
• Hormonal Health — restoring balance to your endocrine system
• Emotional Well-Being — addressing stress, anxiety, and mental health
• Nutrition — fueling your body with the right foods and nutrients

When these pillars are in balance, your body has the foundation it needs to heal. When they're out of balance, chronic illness can develop and persist.

While both approaches aim to treat the whole person, functional medicine is rooted in systems biology and uses advanced lab testing to identify specific biochemical imbalances. Dr. Harrison uses comprehensive functional medicine lab panels, physical examinations, and detailed health histories to create a data-driven picture of what's happening in your body.

Naturopathic medicine may incorporate herbal remedies, homeopathy, and other alternative therapies. Dr. Harrison's approach integrates clinical nutrition, lifestyle interventions, and evidence-based protocols to correct the underlying mechanisms driving chronic illness.

Functional medicine is holistic in the sense that it looks at the whole person — body, mind, and lifestyle — rather than isolating individual symptoms. However, it goes beyond what many people think of as "holistic medicine" by using cutting-edge laboratory testing and evidence-based science to precisely identify biochemical imbalances, metabolic dysfunction, and immune system problems.

Dr. Harrison combines this scientific approach with personalized nutrition, lifestyle strategies, and patient education to create lasting results.

Functional medicine isn't about replacing your regular doctor — it's about filling the gaps that conventional medicine often leaves, especially when it comes to chronic and complex conditions. Conventional medicine excels at acute care, emergencies, and infections. But for conditions like autoimmune disease, chronic fatigue, gut problems, and hormonal imbalances, the conventional model of prescribing medications to manage symptoms often falls short of addressing the root cause.

Functional medicine asks why those symptoms are happening and works to correct the underlying problem. Many of Dr. Harrison's patients continue to see their primary care doctor while working with him for their chronic health issues.

Yes. Functional medicine is grounded in peer-reviewed science, systems biology, and advanced diagnostic testing. It uses the same biochemistry and physiology taught in medical schools but applies it differently — focusing on restoring optimal function rather than just managing disease.

Research continues to validate the role of nutrition, gut health, inflammation, and metabolic function in chronic disease. Major academic institutions including the Cleveland Clinic, IFM (Institute for Functional Medicine), and others have embraced functional medicine approaches. Dr. Harrison has personally witnessed transformative results with his patients over his decade-plus career.

Dr. Harrison uses comprehensive functional medicine lab testing that goes well beyond standard blood work. Depending on your case, this may include:

• Full thyroid panels (TSH, Free T3, Free T4, Reverse T3, thyroid antibodies)
• Complete metabolic and inflammatory markers
• Advanced hormone testing
• Functional blood chemistry analysis
• Gut health assessments (stool testing, SIBO breath tests)
• Food sensitivity testing
• Nutrient deficiency panels
• Adrenal function testing
• Markers for oxidative stress and immune function

The goal is to build a detailed, data-driven picture of your body's biochemistry so the care plan is precise and targeted — not based on guesswork.

Dr. Harrison specializes in chronic and complex health conditions, including:

• Thyroid disorders — Hashimoto's, hypothyroidism, hyperthyroidism
• Autoimmune diseases — lupus, rheumatoid arthritis, MS, psoriasis, and more
• Adrenal fatigue and HPA axis dysfunction
• Gut health issues — IBS, SIBO, leaky gut, food sensitivities, Crohn's, colitis
• Allergies — environmental and food-related
• Brain health — brain fog, cognitive decline, anxiety, depression
• Diabetes and pre-diabetes
• Hormone imbalances — estrogen, testosterone, progesterone, cortisol
• Cardiovascular health — high blood pressure, cholesterol, metabolic syndrome

If you're struggling with a chronic condition and haven't found answers through conventional medicine, schedule a free discovery call to discuss your situation.

Yes. Autoimmune conditions are one of Dr. Harrison's primary areas of focus. Rather than simply suppressing the immune system with medications, functional medicine seeks to understand what is triggering the autoimmune response — whether it's gut dysfunction, food sensitivities, chronic infections, environmental toxins, or hormonal imbalances.

By identifying and addressing these underlying triggers, many patients experience significant improvements in their symptoms and quality of life. Dr. Harrison works with patients who have conditions like Hashimoto's thyroiditis, rheumatoid arthritis, lupus, multiple sclerosis, psoriasis, Sjögren's syndrome, and many other autoimmune disorders.

Absolutely. Thyroid disorders — especially Hashimoto's thyroiditis — are among the most common conditions Dr. Harrison works with. Standard medical care often focuses only on TSH levels and thyroid medication, but functional medicine looks at the full thyroid panel (TSH, Free T3, Free T4, Reverse T3, thyroid antibodies), nutrient deficiencies (selenium, zinc, vitamin D, iron), gut health, and immune system triggers.

By addressing the underlying autoimmune and inflammatory drivers, many patients see significant improvements in energy, weight, mood, hair loss, and overall thyroid function — often achieving results they couldn't get with medication alone.

Functional medicine has shown significant promise in helping patients manage and even reverse type 2 diabetes and pre-diabetes by addressing the underlying metabolic dysfunction — not just blood sugar numbers. Dr. Harrison has personal experience with this, having reversed his own type 2 diabetes through functional medicine principles during chiropractic school.

The approach focuses on correcting insulin resistance, optimizing nutrition, reducing inflammation, improving gut health, and supporting healthy metabolic function. Every patient's plan is individualized based on their lab results, health history, and specific needs.

Yes, and this combination of symptoms is something Dr. Harrison sees regularly. Brain fog, chronic fatigue, and digestive problems are often interconnected — they can stem from gut dysfunction, blood sugar imbalances, hormonal disruption, adrenal fatigue, nutrient deficiencies, or chronic inflammation.

Rather than treating each symptom in isolation with separate specialists, Dr. Harrison's approach looks at how these systems interact and works to identify the common root cause. Through detailed lab testing, a thorough health history, and a personalized care plan, many patients find resolution for symptoms they've been dealing with for years.

Yes. Gut health is foundational to overall health, and it's a major focus of Dr. Harrison's practice. Conditions like irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), leaky gut (intestinal permeability), food sensitivities, and inflammatory bowel conditions are all addressed through a root-cause approach.

This may include specialized gut testing, dietary protocols, targeted supplementation, and strategies to repair the gut lining and restore a healthy microbiome. Many patients with chronic gut issues find lasting relief through this approach after years of failed conventional treatments.

Many cases of anxiety and depression have underlying physiological drivers that conventional psychiatry doesn't address — things like gut-brain axis dysfunction, chronic inflammation, blood sugar instability, nutrient deficiencies (B vitamins, magnesium, vitamin D, omega-3s), hormonal imbalances, and adrenal dysfunction.

Dr. Harrison's approach investigates these root causes through comprehensive lab testing and works to correct the biochemical imbalances that may be contributing to your mental health symptoms. This approach can work alongside conventional mental health care.

Yes. Hormonal health is one of the six pillars of health that Dr. Harrison focuses on. Whether you're dealing with estrogen dominance, low testosterone, progesterone imbalances, cortisol dysregulation, or other endocrine issues, the functional medicine approach uses advanced hormone testing to understand the full picture — not just individual hormone levels, but how they interact with each other and with your metabolism, gut health, and stress response.

Treatment plans may include targeted nutrition, lifestyle changes, stress management, detoxification support, and other evidence-based protocols to restore hormonal balance naturally.

Yes. What's commonly called "adrenal fatigue" — more accurately described as HPA (hypothalamic-pituitary-adrenal) axis dysfunction — is a condition Dr. Harrison frequently addresses. Chronic stress, poor sleep, overwork, and underlying health conditions can dysregulate your cortisol rhythm, leading to persistent fatigue, difficulty waking up, afternoon crashes, anxiety, and poor stress tolerance.

Through adrenal function testing and a thorough health assessment, Dr. Harrison identifies where your stress response has broken down and creates a targeted plan to restore healthy adrenal function.

Yes. Chronic allergies — whether environmental, food-related, or both — often point to an underlying immune system imbalance, gut dysfunction, or chronic inflammation. Rather than simply prescribing antihistamines, Dr. Harrison works to understand why your immune system is overreacting and addresses the root triggers.

This may involve gut healing protocols, food sensitivity testing, immune modulation strategies, and addressing underlying factors like leaky gut or hidden infections that are keeping your immune system on high alert.

Yes. Dr. Harrison takes a comprehensive approach to cardiovascular health that goes beyond simply looking at total cholesterol. Functional medicine evaluates advanced cardiovascular markers including particle size, inflammatory markers (like hs-CRP), insulin resistance, oxidative stress, and metabolic syndrome indicators.

By addressing the metabolic and inflammatory drivers of cardiovascular risk — through nutrition, lifestyle optimization, and targeted interventions — many patients are able to significantly improve their heart health and reduce their risk factors.

The timeline varies depending on the complexity of your condition and how long you've been dealing with it. Some patients notice improvements within the first few weeks, while more complex cases may take several months of consistent work.

Dr. Harrison takes a step-by-step approach — building your health one layer at a time, like constructing a house brick by brick. Regular check-ins and follow-up lab testing help track progress and make adjustments along the way. The focus is always on sustainable, lasting results — not quick fixes.

This depends on your individual situation. Chronic conditions that have developed over years don't resolve overnight. Dr. Harrison's process includes an initial investigation phase (Steps 1–4), followed by an active care phase where your clinical master plan is implemented, and then periodic follow-ups to track progress through lab testing and adjustments.

Some patients work with Dr. Harrison for several months, while others with more complex cases may benefit from a longer relationship. Your care plan and expected timeline will be clearly outlined during the Lab Review & Clinical Master Plan appointment.

In most cases, nutrition is a key component of your care plan — but Dr. Harrison doesn't believe in crash diets or extreme protocols. Instead, changes are introduced gradually and sustainably, designed to fit your actual life and preferences. The goal is to build eating habits that support your healing and that you can maintain long-term.

Specific dietary recommendations will be based on your lab results, symptoms, and health goals. For example, some patients may need to address food sensitivities, blood sugar regulation, or gut healing through targeted dietary adjustments.

Supplementation may be part of your care plan depending on your lab results. Functional medicine uses targeted, evidence-based supplementation to correct specific deficiencies and support healing — not a shotgun approach of taking dozens of random vitamins.

If supplements are recommended, Dr. Harrison will explain exactly why each one is needed, what it does, and how long you'll likely need it. The goal is always to address the underlying issue so that long-term supplementation is minimized.

Dr. Harrison is a Doctor of Chiropractic specializing in functional medicine, and his approach focuses on correcting root causes through nutrition, lifestyle, and evidence-based natural interventions. He does not prescribe pharmaceutical medications. However, he works collaboratively alongside your existing medical doctors when needed, and if outside expertise is required (which is rare), he will collaborate with specialists to ensure seamless care.

Yes, functional medicine is very safe. The approach focuses on natural, evidence-based interventions — optimizing nutrition, correcting deficiencies, improving gut health, reducing inflammation, and supporting your body's own healing mechanisms. There are no invasive procedures involved.

Dr. Harrison's care is guided by thorough lab testing and clinical assessment, ensuring that every recommendation is tailored to your unique physiology. He monitors your progress through regular follow-ups and adjusts your plan as needed.

Absolutely. Many of Dr. Harrison's patients continue to work with their primary care physicians, endocrinologists, or other specialists while receiving functional medicine care. The approaches complement each other — Dr. Harrison focuses on identifying and addressing root causes, while your conventional doctors manage acute care and medications as needed.

Several things set Dr. Harrison apart:

• He only takes patients he's confident he can help — your success is his success.
• His approach is methodical and step-by-step — like building a house brick by brick, not chasing health fads or quick fixes.
• Health independence is the goal — he doesn't just treat you; he teaches you to understand your own body so you can maintain your health long-term.
• He provides mentorship and accountability — not just information, but the coaching and follow-through needed for real transformation.
• Personal experience — having overcome his own chronic health challenges (including type 2 diabetes) through functional medicine, he brings deep empathy and understanding to his patients.

Many of Dr. Harrison's patients come to him after feeling lost, overwhelmed, and defeated — having seen multiple doctors without getting real answers. His practice is specifically designed for people in this situation.

Functional medicine takes a completely different approach than conventional care. By conducting a thorough clinical investigation — including advanced lab testing that most conventional doctors don't run, a detailed health history, and a comprehensive physical exam — Dr. Harrison looks for the underlying biochemical imbalances that other providers may have missed. His step-by-step process is built to uncover every detail and create a precise, personalized plan.

The first step is a free discovery call to discuss your situation and see if his approach is right for you.

At a typical doctor's office, you might get 10–15 minutes, basic lab work, and a prescription. At Dr. Harrison's Center of Functional Medicine, you get a comprehensive health investigation that includes detailed history reviews, advanced functional lab testing, a physical exam, and a personalized clinical master plan.

The focus is on understanding your health — not just managing symptoms. Dr. Harrison takes the time to explain what's happening in your body, why, and exactly what steps need to be taken. You leave with education, a plan, and ongoing support — not just a prescription.

Health independence is Dr. Harrison's core philosophy. It means empowering you with the knowledge, tools, and understanding to take control of your own health — so you're not dependent on anyone, including him, for the rest of your life.

Through education, mentorship, and coaching, Dr. Harrison teaches his patients to understand their own bodies so well that if a problem arises in the future, they know exactly how to respond. The goal isn't just to get you feeling better today — it's to give you the confidence and capability to maintain vibrant health for years to come.

While Dr. Harrison specializes in chronic and complex conditions, functional medicine can also benefit people who aren't necessarily "sick" but want to optimize their health, prevent future disease, or understand why they don't feel as good as they think they should. If you feel like something is off but your regular doctor says everything looks "normal," functional medicine often uncovers imbalances that standard testing misses.

Dr. Harrison has helped patients from across the country and around the world achieve life-changing results — from resolving chronic fatigue and brain fog, to managing autoimmune conditions, reversing metabolic disorders, restoring hormonal balance, and healing gut dysfunction. Many patients describe their experience as transformative, having regained energy, mental clarity, and quality of life they thought was gone forever.
