Functional Neurology & Integrative Medicine

When everything else has failed, this is where people find answers.

Dr. Blake Ambridge brings 39 years of experience across functional neurology, functional medicine, and naturopathic care — looking for the pattern where others have found only symptoms.

When you know something isn't right

You know your body. You know when something is off.

Many people spend years being told their labs are normal while they continue to suffer. Dr. A looks beyond isolated symptoms to understand how the brain, nervous system, body, and gut work together.

  1. 01

    Still searching for answers

    You have visited multiple doctors only to be told your labs are “normal” while you still feel unwell. You are not alone, and you are not imagining it.

  2. 02

    More than a symptom

    Chronic pain, fatigue, brain fog, and gut issues are not always isolated events. They can be systemic signals of underlying imbalances that have been missed.

  3. 03

    Ready to move forward

    By looking for root causes rather than stopping at isolated diagnoses, we can create a clearer path toward physical freedom, cognitive sharpness, and daily vitality.

Dr. Blake Ambridge does not treat diagnoses in isolation. He treats people. After 39 years and thousands of complex cases, his approach remains consistent: understand the complete pattern, identify the foundational imbalance, and build care around the individual.

Patients travel to Sandpoint after years of searching because Dr. A combines disciplines that are too often separated — and brings them together in one thoughtful clinical conversation.

The story behind The Method

When the answers keep changing

Different symptoms can still be part of the same story.

Your symptoms may have shifted over time. The diagnosis may have changed—or never quite explained how you feel. Dr. A looks across systems to find the pattern beneath the individual pieces.

  • Anxiety
  • Fatigue
  • Brain fog
  • Persistent pain
  • Digestive changes
  • Dizziness
  • Sleep disruption
See how Dr. A connects the puzzle pieces

Complex cases are our specialty

We don't ask you to fit a diagnosis before you can be helped. Many of our patients arrive without one. What they arrive with is a body that isn't working the way it should — and a history of being told it should be.

No two plans are the same because no two people are the same.

What your first visit looks like

One integrated plan

Three levels of care. One doctor looking at everything.

Every patient receives care that draws from three integrated levels. Most people need more than one.

  • Fine stems strung with dewdrops, branching like a network of nerves

    Neurological Care

    Brain and nervous system assessment and treatment — evaluating how the brain and body are communicating, and what's breaking down in that conversation.

    Functional Care

    A deep investigation into the metabolic, immune, hormonal, and inflammatory factors driving chronic conditions. Longer appointments. More thorough testing.

    Restorative Care

    Advanced therapies to support tissue healing, regeneration, and long-term resilience, drawing on the naturopathic and regenerative training Dr. A added in 2019.

The man behind the methodology

39 years of asking why

Dr. F. Blake Ambridge has spent 39 years doing what most practitioners never attempt: looking at the whole person at once.

His training spans chiropractic neurology, naturopathic medicine, functional medicine, and rehabilitation. He studied under two of the physicians who shaped the modern practice of neurological rehabilitation and manual therapy. He speaks nationally to other healthcare practitioners. And he still sees every patient himself.

Patients come to Sandpoint from across the country because there are very few people in the world who do what Dr. A does — and because when they sit down with him, they feel, for the first time in years, that someone finally understands what's going on.

39 years. Thousands of patients. One consistent finding: the root cause is almost never what you think it is.
