Consulting & Education for MCAS, POTS, Dysautonomia & Related Conditions

-This is not just symptom management.

This is stabilization architecture.

Welcome to New Leaf Neuro

We work with individuals living with MCAS, POTS, dysautonomia, Long COVID, and related complex conditions. Many people are left managing challenging day-to-day symptoms without clear guidance, especially when routine testing does not fully explain what they are experiencing.

These conditions often involve dysregulated patterns in nervous system signaling, circulation, and immune activation. The symptoms are real and physiologic — they are not imagined.

New Leaf Neuro focuses on this missing piece. We provide structured consulting and education that helps clients recognize physiological patterns and apply organized strategies — the practical decision-making that often falls outside traditional medical visits.

Does This Sound Familiar?

✓ You’ve seen multiple doctors but still don’t have clear answers
✓ Symptoms shift and don’t follow predictable rules
✓ You react to foods, stress, temperature, or exertion
✓ You feel stuck managing flares instead of improving
✓ You’ve been told “everything looks normal”

You are not imagining this.
These patterns are commonly seen in neuro-immune and autonomic dysregulation.

-There is a way forward.
We’ll walk it with you.

Stabilize. Regulate Optimize

Meet the Founders

Liz McGhee
Founder & Lead Consultantt

Liz is an environmental health scientist and cell and molecular biologist. She leads the live New Leaf Neuro sessions and helps participants understand their symptoms and recognize patterns affecting stability. Her focus is making complex physiology understandable so people feel less overwhelmed and know what to do next to move forward.

Pascal Boudreau
Co-Founder & Program Director

Pascal is an electrical engineer with a systems-analysis background and a focus on recognizing patterns in complex symptoms. During live sessions he helps guide discussion, answer questions, and support participants as they apply the material to daily life. He also assists with program organization, helping turn complex concepts into clear, manageable steps.

Supporting Recovery Thru Education & Consulting

“The first step in solving any problem is understanding it.”
— William Edwards Deming

MCAS, POTS, dysautonomia and dysregulated nersous system disorders often involve fluctuating and confusing symptoms, making it difficult to know what to focus on or what to do next.

At New Leaf Neuro, we help you understand what your body is doing and why. You learn how nervous system regulation, circulation, and immune reactivity connect — and how to respond in a steady, structured way rather than reacting to each flare.

We offer two ways for individuals to work with us. The first is our 6-week Online Live Stabilization Class. Taught weekly by Liz and Pascal, each session includes teaching, group discussion, and real-time Q&A. This is where most clients begin. The class is designed to stand on its own, helping you build the understanding and practical tools needed to support stability and regulation. Our live format provides clarity, structure, and support so you are not navigating this alone.

For those who want additional guidance or are working through more complex patterns, individual consulting is also available alongside, after or on completely on its own.

You’re not broken. These symptoms reflect nervous system dysregulation—something we understand and know how to work with.

Common Issues w/ Dysregulated Nervous System Disorders

I'm Constantly Chasing Symptoms

I'm constantly chasing symptoms, visiting doctors who never have answers. My symptoms remain unexplained and often unrelated.

Countless Scans & Tests - No Answers

I have had so many scans and blood test that never seem to bring answers or clarity to my issues.

I Have Massive
Brain Fog

My brain fog, memory loss, and mental fatigue make daily tasks so overwhelming.

I Feel Hungover, Like My Body Is Poisoned

I feel hungover and sick, as if poisoned, despite not drinking any alcohol.

I End Up At The Emergency Room Too Often

Countless ER visits, no answers and no relief.

I've Been Diagnosed With (POTS) What Now?

I feel stuck, even slight movement sends my heart racing. Despite increasing salt and following a specialized exercise plan, my symptoms remain or worsen.

I'm Scared—Will This Ever Get Better?

I am getting no relief—will I always have to just manage symptoms?

I Have Developed Anxiety and/or Phobias

I have developed unexplained fears and anxiety I’ve never had before.

Everything Makes My Body React

My body reacts to everything—food, chemicals, EMFs, heat, and more—causing symptoms from anaphylaxis to asthma, hives, palpitations, and GI issues. What’s happening?

It's Not Just Stress

Yes, I have some stress but this is not just stress. I am tried of being prescribed anti-anxiety meds, and then being referred to a psychiatrist.

I Am Always
Exhausted

I am beyond tired, despite rest, with aching muscles and heaviness.

My Body Feels Overstimulated

Loud sounds, bright lights, crying on TV can trigger agitation and overstimulation.

So What Can Cause These Issues?

In conditions such as MCAS, POTS, dysautonomia, chronic anxiety, Long COVID, and other complex chronic illnesses symptoms are often mediated through nervous system patterns — which is why regulation becomes such an important focus.
When the nervous system remains in a state of over activation, it can disrupt immune, cardiovascular, and biochemical systems.
