Welcome to Nutrition & Wellness with Mariah Campoy, DMSc, PA-C,

I’m so glad you’re here—ready to take empowered steps toward transforming your health and future.

My name is Mariah, and I’m an Arizona native with a deep passion for blending medicine, nutrition, and holistic care. I’m a certified Physician Associate (PA-C), Functional Medicine Provider, Certified Health Coach, and Nutritionist. My academic background includes a Bachelor of Science in Nutritional Sciences with minors in Psychology and Biochemistry from the University of Arizona, a Master of Science in Physician Assistant Studies from Northern Arizona University, and a Master of Science in Nutritional Sciences from Arizona State University. I recently completed my Doctor of Medical Science (DMSc) with a focus on expanding access to nutrition and integrative healthcare through leadership and innovation.

In addition to this platform, I’m the founder of NutriwellProvider, a virtual functional medicine and nutrition practice designed to help individuals understand the root causes of their health concerns and take personalized steps toward healing. Through NutriwellProvider, I combine evidence-based medicine with nutritional science to create custom plans for people looking to improve energy, hormones, digestion, metabolism, and more.

This website began as a simple resource for my patients—but I quickly realized it could help so many more people who are eager to learn, but overwhelmed by complex or conflicting advice. Here, you’ll find approachable, research-backed guidance that empowers you to feel your best from the inside out.

Whether you’re here to prevent chronic disease, optimize your health, or simply feel better day to day—I’m here to support you.

Let’s get started—your journey begins now.
