FUNCTIONAL MEDICINE FOR PERIMENOPAUSE

You're not crazy. You deserve someone who will actually look

If you're exhausted, foggy, gaining weight, and tired of being told your labs are "normal," you're in the right place. At GrassRoots, we find the real, root-cause reason perimenopause is stealing your energy, your clarity, and your sense of yourself and we build a plan around you.

YOU'VE BEEN HERE

The problem was never you

You've sat across from a doctor who ran a single thyroid test, told you everything looked normal, and sent you home still feeling like a stranger in your own body.

Maybe you were offered an antidepressant. Maybe you were told to try yoga, or sleep more, or that this is just what happens to women your age. Maybe you started to wonder if it really was all in your head.

It isn't. The exhaustion is real. The brain fog is real. The weight, the anxiety, the 3 a.m. wake-ups, the way you don't quite feel like yourself anymore — all real, and all connected. The problem was never you. The problem was that no one looked at the whole picture.

Why nothing has worked

It isn't one number. It's a connected web.

Here's what almost no one explains. Perimenopause isn't one number going out of range. It's a connected web of systems shifting at the same time your hormones, your thyroid, your stress response, your metabolism, your gut and when someone only checks one thread, they miss the whole thing. That's why the standard workup keeps coming back "normal." It was never built to see this. And it's why treating one symptom at a time, one prescription at a time, leaves you stuck.

Hormones Thyroid Stress response Metabolism Gut
What we actually do

The opposite of a rushed appointment and a quick prescription.

Run the full picture

Not just a TSH

Hormones including the progesterone no one checks, complete thyroid, real metabolic markers, inflammation, nutrients, gut.

Find the root cause

The whole web

How the whole web connects — so your plan addresses why you feel this way, not just the loudest symptom.

Build it around you

A real care team

Clinician, nutrition, coaching — not an app and an auto-refill.

GLP-1, differently

Muscle protected

Metabolic testing and body-composition tracking — never inject-and-hope.

A prescription is not a plan. We're here for the healing.

WHAT A DISCOVERY CALL IS

No pressure.
No rush.
No dismissal.

The next step is a free discovery call. It's a no-pressure conversation with our team to hear your story,
understand what you've been through, and figure out whether what we do is the right fit for you.

No one will rush you.
No one will dismiss you. That's a promise.

Why I built GrassRoots

I was the patient. Now I'm the clinician.

Years ago, I was a high-performing clinician with debilitating symptoms — brain fog, tremors, joint pain, cognitive decline. I went to specialist after specialist. Every test came back "normal." I was told it was stress, then anxiety, then that I needed an antidepressant. No one was investigating why. It took the right testing, finally, to reveal what everyone had missed. I recovered through a root-cause approach that looked at my whole system instead of one symptom at a time. And I made it my life's work so that no one who comes to me ever has to feel that dismissed again. Every woman who walks into GrassRoots exhausted and unheard is the person I once was. That's why we'll never give up on you.

Quick FAQ

Do you take insurance?

We're a cash-pay practice, which is exactly what lets us spend the time and run the depth a real root-cause workup requires. We provide superbills you can submit for possible out-of-network reimbursement, and we accept HSA/FSA.

Do I have to be local?

We see patients in person at our West Lebanon, NH clinic, and we provide telehealth care in New Hampshire, Vermont, Texas, and Florida. Not in those states, or not ready for a program? Watch for Perimenopause Unmasked, the course where I teach you everything I'd teach you in my office.

Is this just hormones?

No. Hormones may be part of your plan, but we look at the whole web: thyroid, metabolism, stress, gut, nutrients because that's what actually drives how you feel.

You've spent long enough being told to just live with it.

You don't have to. Let's actually look.
