Inside the work

What you can expect when
we work together

This is not a quick fix or one-size-fits-all plan. It's a collaborative, personalized process designed to help you feel supported, informed, and empowered every step of the way.

01

Your Full Health History

We begin by understanding the complete picture — your symptoms, history, and what's brought you here — so nothing gets missed and nothing gets dismissed.

02

Root-Cause Functional Lab Testing

Using specialty lab testing beyond standard panels, we identify what's actually driving your symptoms — so we can address the source, not just the surface.

03

Personalized Nutrition Plans

No generic protocols or crash diets. Your nutrition plan is tailored to your body, your symptoms, and your real life — so it actually works for you.

04

Nervous System & Lifestyle Integration

Healing isn't just physical. We incorporate nervous system regulation and sustainable lifestyle shifts that support your body's ability to recover and truly heal.

  • “We were lucky enough to get pregnant on our first go and Ana’s advice played a key role in that”

    I was preparing to conceive after receiving a Hashimoto’s diagnosis. The best things about working with the practice is Ana is she is thoughtful, patient and curious. She never made me feel rushed and she provided insights and suggestions that I hadn’t heard before, even after working with other functional doctors. Secondly, getting pregnant!

  • “ I have no more constipation, less painful menstrual cycles, and confidence in my health!”

    I was hoping to better understand and improve my gut health, address painful menstrual cycles, and prepare my body for pregnancy. I was able to reach all of my goals and feel like I'm in control of my health for the first time!  Every aspect was so well organized and easy to follow. Truly worth every penny.

Hey, I’m Ana Cristina Lewis!

registered dietitian and functional nutritionist

I know this experience personally. I dealt with ongoing digestive symptoms, debilitating periods, and painful adult-onset acne—all while being told I was “fine.” Even when I knew something wasn’t right, I was left without real answers or a clear path forward. That experience is what led me to approach health differently. It guided my own path into functional medicine and a deeper, root-cause approach to healing. I’ve also navigated my own health journey through PCOS and went on to have healthy pregnancies—something that further shaped how I support women through hormone health, fertility, and pregnancy. Today, as a mom, I understand that healing has to fit into real life. Nutrition and lifestyle changes should feel simple, nourishing, and sustainable—not extreme or overwhelming for you or your family. This work is deeply personal to me—and it’s why I care so much about helping women feel truly seen, supported, and understood in their health journey.

Frequently Asked Questions

  • This program goes beyond general nutrition guidance. Using specialty lab testing and a thorough health history, we look for the root causes behind your symptoms and build a plan that's specific to your body — not a generic protocol.

  • We use functional lab testing that goes beyond standard panels — looking at hormones, gut health, nutrients, and other markers that often get missed in conventional care. Testing is tailored to what your symptoms and history point to, so we're not running labs for the sake of it.

  • No. Many clients come in without a clear diagnosis — just a long list of symptoms and no real answers. You don't need to have everything figured out before we start. That's exactly what this work is designed to help with.

  • Yes. I works virtually with clients across the US, so location is never a barrier.

  • The best way to find out is to apply. Ana reviews every application personally and will let you know if this program is the right fit for where you are right now.
