How I Became a Lyme Disease Doctor

Quick Answer: There is no single path to becoming a Lyme disease doctor. It often comes from experience recognizing complex, multi-system illness patterns that don’t fit a typical diagnosis.

Clinical Insight: Many patients with Lyme disease are missed because symptoms span multiple systems and do not follow a single diagnostic pattern.

What makes a Lyme disease doctor?

It’s a question I’m asked often.

The answer is not a single training path—but experience recognizing patterns that others may overlook.

I didn’t set out to become a Lyme disease doctor. My path began in biomedical engineering, shifted to geriatrics, and ultimately led to caring for patients whose symptoms didn’t fit a single diagnosis.

This experience shaped how I practice today—focused on patients with complex, multi-system illness.

This broader approach reflects what I describe in more detail on my About Dr. Cameron page.

The Plan Was Engineering, Not Medicine

I originally planned to become a biomedical engineer. I was drawn to understanding how the body works and designing tools to improve care.

But over time, that path felt incomplete.

Something shifted.

The Pivot Back to Patient Care

I began thinking about the people I grew up with in my small farming community in Minnesota—individuals who often had limited access to specialists and lived with complex health issues.

I realized I didn’t just want to design tools. I wanted to care for patients directly.

So I changed direction and went into medicine.

Training in Geriatrics Shaped My Approach

After medical school, I trained in geriatrics and served as an assistant professor of medicine at New York Medical College, directing medical student training in dementia.

Geriatrics taught me something essential:

Patients rarely have just one problem.

Symptoms overlap. Patterns matter. Listening matters.

This training emphasized recognizing patterns across systems—an approach that would later become central to my work with Lyme disease.

How I Became a Lyme Disease Doctor—Unexpectedly

While caring for patients, I began seeing symptoms that didn’t fit expected patterns.

Some patients had cognitive changes that didn’t match typical dementia. Others had fatigue, joint pain, or neurologic symptoms without clear explanation.

Many had been evaluated extensively—often without answers.

Then a pattern emerged:

Tick-borne illness.

Often Lyme disease. Sometimes co-infections such as Babesia or Bartonella.

Many had been told they had post-treatment Lyme disease syndrome and that nothing more could be done.

But careful evaluation often revealed a more complex picture—and many patients improved with treatment.

That was the turning point.

What Makes a Lyme Disease Doctor Different?

Lyme disease is not a single-system illness.

It can affect the nervous system, joints, heart, immune system, and cognition.

Symptoms may shift, overlap, and fluctuate.

This reflects a broader challenge in why Lyme disease tests the limits of medicine.

Recognizing these patterns—rather than focusing on a single diagnosis—is what defines experienced Lyme disease care.

Treating Lyme Disease Requires Listening First

The CDC acknowledges that some patients experience persistent symptoms after treatment.

In my experience, understanding Lyme disease requires understanding the whole patient—not just test results.

This includes:

• Careful clinical history
• Recognition of multi-system symptoms
• Assessment for co-infections
• Individualized treatment decisions

---

This Is the Work I Was Meant to Do

Today, my work focuses on patients with Lyme disease and co-infections—and the complexity that comes with them.

What began as an interest in engineering led to geriatrics. Geriatrics led to pattern recognition. And that ultimately led to Lyme disease care.

This wasn’t a planned path.

But it became the right one—one patient at a time.

---

Clinical Takeaway

Becoming a Lyme disease doctor is less about a specific training path and more about experience recognizing complex, multi-system illness patterns.

Patients with Lyme disease often present with symptoms that do not fit a single diagnosis, requiring careful listening and pattern recognition across systems.

This approach—rather than reliance on a single test or specialty—often makes the difference in identifying and treating Lyme disease effectively.
