Meet Alyssa

Hi, I'm Alyssa — 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 roadmap built around the whole person.

Root Cause. Whole Person. Lasting Hope.

About

My Story

Alyssa Roberge Cook, RN, BSN, 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.

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 clues. They're invitations to look deeper. When we stop viewing symptoms in isolation and begin connecting the dots, we often uncover patterns that tell a much more complete story.

"Symptoms aren't random—they're clues."

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. Today, I feel healthier than I did a decade ago, and that journey has only strengthened my belief that the body has an incredible capacity to heal when it's given the right conditions and support.

That belief became the foundation of Hosanna Functional Health.

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, genetics, and laboratory data to better understand the patterns that may be contributing to how you feel. From there, we'll create a personalized wellness roadmap designed to support your body's natural ability to heal and thrive.

Your body was created with incredible and miraculous wisdom. My hope is to help you understand what it's been trying to tell you all along—because when you understand the why behind your symptoms, you're empowered to make lasting changes that support lifelong health.

Our Mission

The name Hosanna comes from the Hebrew phrase meaning "save us" or "please help us." Throughout Scripture, it began as a desperate cry for deliverance and later became a joyful declaration of praise and hope.

That transformation perfectly reflects the mission behind Hosanna Functional Health.

Many women turn to Hosanna, exhausted, discouraged, and wondering why they don't feel like themselves. They've been told their labs are "normal," their symptoms are unrelated, or that they simply have to learn to live this way.

At Hosanna, we look beyond isolated symptoms to understand the whole person. We believe the body leaves clues, that healing begins by asking better questions, and that lasting wellness comes from addressing the factors that may be contributing to dysfunction—not simply managing symptoms.

Our mission is to educate, empower, and equip women with a deeper understanding of their own health through evidence-informed guidance, comprehensive specialty testing, and personalized wellness strategies.

Because when you understand your body, you can begin working with it instead of against it.

Whether you're navigating fatigue, digestive issues, hormone imbalances, autoimmune concerns, or preparing your body for a healthy pregnancy, our hope is that your journey mirrors the meaning of our name—from a cry for help to a life marked by hope, healing, and renewed purpose.
