Meet Alyssa

Hi, I'm Alyssa. I'm a Registered Nurse and functional medicine practitioner for women.

I walked my own long road through chronic symptoms and "normal" labs before functional medicine helped me finally understand what my body was trying to say. Now I help women do the same, with comprehensive specialty testing, careful listening, and a personalized plan built around the whole person.

About

My Story

Alyssa Roberge Cook, BSN, RN, BC-FMP

For much of my life, I struggled with chronic digestive issues and what felt like an ever-growing list of seemingly unrelated symptoms—including fatigue, anxiety, depression, hormone imbalances, skin concerns, and immune dysfunction. Despite normal labs and conventional testing, I knew there had to be more to the story.

Everything changed when I discovered functional medicine. Through comprehensive specialty testing, I uncovered underlying imbalances that conventional testing had never explored—including gut dysfunction, chronic infections, mold illness, nutrient deficiencies, hormone imbalances, and genetic factors that helped explain why my body had been struggling.

What once felt like a collection of unrelated symptoms finally began to make sense and that experience completely changed the way I view health.

I learned that the body is always communicating with us. Symptoms aren't random—they're often clues to underlying dysfunction and invitations to look deeper. When we focus on managing symptoms rather than addressing what's driving them, those underlying issues can go unresolved for years, potentially contributing to chronic disease.

Today, I feel healthier than I did a decade ago, and my journey has only strengthened my belief that the body has an incredible capacity to heal when given the right conditions and support. That belief became the foundation of Hosanna Functional Health.

As I entered my 30s, that philosophy naturally expanded into fertility. I realized fertility isn't something we simply "wait and see" about. It's something we prepare for by building health long before pregnancy.

As a Registered Nurse with training in functional medicine, my role is to educate, guide, and empower women through comprehensive specialty testing and evidence-informed wellness strategies. Together, we'll explore your health history, lifestyle, environment, and specialty testing to better understand what may be contributing to how you feel.

Our Mission

The name Hosanna comes from the Hebrew phrase meaning “save us” or “please help us.” What began as a cry for deliverance became a declaration of praise and hope. That transformation is at the heart of Hosanna Functional Health.

So many women are exhausted, frustrated, and searching for answers after being told their labs are “normal” or that their symptoms are simply something they have to live with. I believe women deserve more than symptom management. They deserve to understand what’s happening in their bodies and why.

At Hosanna, we focus on connecting the dots through comprehensive testing, personalized wellness strategies, and education. My mission is to empower women to take an active role in their health, address underlying imbalances, and prioritize prevention.

My hope is that Hosanna represents the same transformation for you—from searching for answers to finding hope, understanding, and a path toward lasting wellness.

Root Cause. Whole Person. Lasting Hope.

"Heal me, O Lord, and I shall be healed; save me, and I shall be saved, for you are my praise."
Jeremiah 17:14

Testing

Lab Testing

Standard labs often come back "normal" even when you don't feel normal. These tests look deeper. Every Signature Program client gets comprehensive blood work and two functional tests chosen for them, and additional tests can be added if needed.

Tap a test to see what it looks at.

Comprehensive Blood Chemistry
Why do I feel off when my labs are "normal"?A full blood panel covering thyroid, blood sugar, nutrients, inflammation, and more. I read your results against optimal ranges as well as standard ones, which helps catch patterns early.
Comprehensive Stool Analysis (GI-MAP)
What's going on in my gut?An at-home stool test that shows the balance of helpful and harmful bacteria in your gut, along with signs of infection, inflammation, and how well you're digesting food.
SIBO Breath Test
Why am I bloated after I eat?An at-home breath test that looks for signs of too much bacteria in the small intestine (called SIBO), a common source of bloating, gas, and irregular bowel movements.
DUTCH Complete Hormone Test
What are my hormones actually doing?An at-home dried urine test that shows your sex hormones, your cortisol (stress hormone) pattern through the day, and how your body processes hormones. It's timed to your cycle for accurate results.
Organic Acids Test
Why am I so tired?A urine test that gives a broad look at how your body makes energy, your nutrient levels, yeast and bacteria in the gut, and how well you're clearing waste.
Food Allergy or Sensitivity Testing
Which foods are bothering me?A blood test that shows how your immune system reacts to common foods, so changes to your diet are targeted instead of guesswork. We choose allergy or sensitivity testing based on what you need.
Mycotoxin (Mold) Test
Could mold be part of this?A urine test that looks for toxins from mold, which can build up from time spent in a water-damaged home or workplace.
Environmental Toxin & Heavy Metal Testing
Are toxins driving my dysfunction?Checks for common chemicals and metals, like BPA and phthalates from plastics, PFAS ("forever chemicals"), glyphosate, lead, mercury, and arsenic.
Genetic Testing
How is my body designed?Looks at genetic differences that affect how you use nutrients, clear toxins, and handle inflammation, so nutrition and supplements can be fit to you.
