About Dr. Martin Hart DC
A Root-Cause Approach to Chronic, Unresolved Illness
I’m Dr. Martin Hart, a functional medicine practitioner dedicated to helping individuals who are dealing with chronic, complex health conditions that often go undiagnosed, misunderstood, or inadequately treated.
​
Many of the people I work with have been struggling for years. They’ve seen multiple providers, tried countless treatments, and are still searching for answers. My work focuses on uncovering the root causes driving persistent symptoms, particularly in cases involving mold illness and Lyme disease, where overlapping infections, inflammation, environmental exposures, and immune dysfunction are frequently at play.
​
All clinical care is provided through my clinic, Keystone Total Health, where I work with clients both in person and virtually.
Clinical Focus and Areas of Specialization
My clinical focus centers on individuals with complex, multi-system illness, with a primary emphasis on mold illness (CIRS) and Lyme disease and chronic infections. These conditions often act as central drivers that disrupt the immune system, nervous system, gut, hormones, and detoxification pathways, leading to a wide range of chronic symptoms.
In addition to mold and Lyme-related illness, my work commonly includes:
-
Inflammation and autoimmune conditions
Commonly including Hashimoto’s thyroiditis, rheumatoid arthritis, psoriatic disease, inflammatory bowel conditions, autoimmune skin disorders, and other immune-driven inflammatory conditions.
​
-
Hormone imbalances
Often involving thyroid dysfunction, adrenal dysregulation, sex hormone imbalances, perimenopause or menopause-related symptoms, and metabolic or blood sugar dysregulation.
​
-
Gut and digestive disorders
Including IBS, SIBO, dysbiosis, chronic bloating, reflux, food sensitivities, impaired digestion, and inflammatory gut patterns.
​
-
Mineral imbalances and toxic load
Frequently associated with heavy metal exposure, environmental toxins, impaired detoxification, electrolyte and mineral depletion, and nervous system dysregulation.
​
-
Chronic fatigue and low energy
Commonly seen with mitochondrial dysfunction, post-infectious fatigue, chronic inflammation, exercise intolerance, and persistent brain fog.
​
-
Pediatric conditions, including PANS/PANDAS
Often involving neuroimmune and inflammatory presentations such as sudden-onset anxiety, OCD, behavioral changes, mood dysregulation, and cognitive or learning difficulties.
​
These issues rarely exist in isolation. Instead, they tend to overlap and reinforce one another, which is why a systems-based, root-cause approach is essential for meaningful progress.
​
Each of these focus areas is treated clinically through Keystone Total Health, where care is tailored to the individual rather than the diagnosis alone.
How I Approach Complex Chronic Illness
Rather than managing symptoms in isolation, my approach is centered on understanding why the body is stuck in a state of dysfunction.
​
For many patients, especially those with mold illness or Lyme disease, this includes evaluating factors such as chronic inflammation, immune dysregulation, gut microbiome imbalance, environmental toxin exposure, persistent infections, and nutrient or mineral depletion.
​
Using advanced functional testing and a personalized clinical framework, I work to identify the underlying drivers contributing to illness and create a targeted plan that supports the body’s ability to heal and regulate itself over time.
​
This process is thorough, data-driven, and individualized, recognizing that complex illness requires more than a one-size-fits-all approach.
