We believe in pairing conventional care with root-cause strategies. Use this page to explore providers and directories you can discuss with your own physician.

Root Cause Medicine

Root Cause Medicine is the future of healthcare — and it’s available now if you know where to look. While traditional medicine often focuses on managing symptoms, Root Cause physicians dig deeper to find why the symptoms are happening in the first place. These doctors can be conventionally trained MDs, Functional Medicine practitioners, or other forward-thinking providers who use advanced tools like genetic testing to uncover hidden deficiencies and biochemical bottlenecks that quietly drive disease.

Here’s the reality: you can eat the cleanest diet in the world, but if your body can’t absorb or process certain nutrients — like B vitamins — you can still end up in serious trouble. We’ve seen cases where a heart attack wasn’t caused by clogged arteries, but by a long-term B-vitamin deficiency due to poor uptake. The ER treats the crisis with medication, but the real solution would have been restoring that nutrient in a form the body could actually use.

Genetic testing can also reveal antioxidant gaps. For example, if you don’t produce enough Superoxide Dismutase — the antioxidant that protects your mitochondria — you may be among the half of people at higher risk for cancer. If you know this in advance, you can supplement strategically and tilt the odds in your favor.

That’s why we recommend everyone have both: a trusted medical doctor and a Root Cause or Functional Medicine provider. This gives you the best of both worlds — rapid intervention in emergencies, and a proactive, personalized plan to keep you from getting sick in the first place.

Functional & Naturopathic Doctors — and Why We Suggest Both

We are not against medical doctors. The conventional medical system is designed to diagnose and treat symptoms — invaluable for acute care and serious diagnoses. We recommend both:

What is a Functional Medicine Doctor?

Clinicians trained to find upstream drivers of disease, integrating advanced labs with nutrition, sleep, stress, toxin reduction, and targeted supplementation.

What is a Naturopathic Doctor (ND)?

Clinicians trained in both conventional sciences and natural therapeutics (nutrition, botanicals, lifestyle). Focused on prevention and restoring function.

Second opinions save time. If you receive a diagnosis, consult your MD/DO and a root-cause clinician to explore all available options — conventional and integrative.
