PRECISION FUNCTIONAL MEDICINE FOR PERIMENOPAUSE, MENOPAUSE & BEYOND

A woman's evolution isn't a problem to fix.

It's a shift in experience, unique to you, that has the power to illuminate your potential.

You're in the right place if you're:

If this sounds familiar
  • Brain fog
  • Insomnia
  • Bloating
  • A body that won't respond anymore
  • Mood swings that disrupt your relationships

Feeling this way isn't something you have to live with. It's an opportunity for transformation so you can thrive in this time of life.

And that's exactly what precision functional medicine is designed for.

Test, Don't Guess

You're not imagining your symptoms, and there is a way to discover the root cause.

Maybe you're in perimenopause, maybe you're further along than that — and maybe no one has actually explained what's happening in your body, just that it's "normal" and you should manage it.

Nobody should hand you a prescription and hope it helps. I look at what's actually happening with your hormones through functional testing — not guess based on your age or a checklist of symptoms.

The DUTCH test — widely considered the gold standard in functional medicine hormone testing — is central to this program because it doesn't just capture a single moment. It shows the full pattern: how your hormones rise and fall across a full day, how your body is metabolizing them, and how your stress response is tied into all of it.

If you've had a blood panel come back "normal" while you still don't feel like yourself, this is often why. You might recognize:

  • Brain fog that makes it hard to focus or find your words
  • Waking up at 3am and not being able to fall back asleep
  • Mood swings, anxiety, or irritability that don't feel like you
  • Hot flashes or night sweats
  • Periods that have become painful, heavy, unpredictable — or stopped showing up at all

Dried Urine Test for Comprehensive Hormones

  • Sex hormones estrogen, progesterone, testosterone
  • Cortisol pattern full-day curve, not a single draw
  • Hormone metabolites how your body processes each hormone
  • Melatonin & oxidative stress sleep and cellular health markers

At-home dried urine collection — no needles, no lab visit required.

One System, Not Three Problems

Your hormones, your gut, and how you're aging aren't separate issues.

Shifting estrogen changes your microbiome and how your gut moves. Gut inflammation changes how your body metabolizes hormones. Your cortisol pattern sits underneath all of it. And together, they drive the inflammation and metabolic changes that determine how you age.

Most care treats each symptom in isolation — a GI referral here, a hormone prescription there, "eat less and move more" from everyone. Nobody connects the dots, and nobody explains it to you.

I look at the whole system through functional testing. I explain what your results show in language you actually understand. And I build one protocol — hormones, gut, nutrition, and biological age — so nothing gets lost between the lab report and your kitchen.

Meet Elizabeth

Clinical credibility, with warmth.

I specialize in hormonal health across perimenopause, menopause, and beyond, digestive dysfunction, longevity science, and biological age reversal. I translate the research into protocols you can actually follow — and because I handle the clinical investigation, the nutrition, and the day-to-day plan myself, nothing is addressed in isolation and nothing gets lost in a handoff.

What sets my work apart is the combination: deep clinical training, measurable outcomes, and the lived experience of the transformation I guide my clients through.

RN MS IFMCP 25 Years Clinical Experience
At 57, I was frustrated by the lack of clear answers from my medical team on how to manage two autoimmune diseases alongside menopause-related weight gain, poor sleep, low libido, and fatigue. Liz thoroughly explained the science behind functional medicine and broke it down in a way that made sense to me. She pushed me when I needed it and supported me every step of the way. The results speak for themselves: I'm sleeping significantly better, my energy is up, my libido has improved, my skin is more radiant — and overall, I feel like myself again.
