Welcome!

Welcome to Copper Sun Nutrition, where the warmth of the Arizona sun meets the power of nourishing food. Led by a Registered Dietitian, we offer personalized nutrition counseling that’s as grounded as the desert and as vibrant as its sunsets. Whether you're looking to find balance in your meals, manage a health condition, or create lasting wellness habits, we're here to walk alongside you on your journey. With an approach rooted in functional nutrition and sustainable change, we’ll help you embrace the path to feeling your best, guided by nature and fueled by the sun.

Hi, I’m Madeline, a Registered Dietitian and founder of Copper Sun Nutrition, proudly based in Arizona. With a deep passion for sustainable change and whole-body wellness, I specialize in helping individuals create a balanced, fulfilling relationship with food—one that supports both their health and their lifestyle.

I hold a Master’s degree in Community Medical Dietetics from Viterbo University and bring years of experience working with a diverse range of clients—from busy entrepreneurs and corporate teams to those managing chronic health conditions or healing their relationship with food. My approach blends the science of nutrition with the art of behavior change, and I’m especially drawn to areas like weight management, hormone health, anti-inflammatory nutrition, and functional wellness.

Whether we’re tackling digestive issues, navigating food sensitivities, or simplifying balanced eating, I’m here to help you connect the dots in a way that feels empowering and realistic. I believe health is not about restriction or perfection—it’s about learning how to nourish your body and honor your needs in a way that lasts.

As a lifelong learner, NPC fitness competitor, and nature lover, I bring a grounded, personalized approach to every session. When I'm not working with clients, you’ll find me practicing yoga, baking, and exploring the Arizona outdoors with my husband and dogs.

At Copper Sun Nutrition, you’ll find support, not shame. Guidance, not gimmicks. And a whole lot of heart.

Testimonials

  • I started looking for a Dietitian to help manage my PCOS, but I also needed someone sensitive to my history of eating disorders, and the challenges of keeping up a nutrition plan as someone with ADHD. Madeline immediately understood these barriers, and really met me where I was. She has helped me get clear on my goals for following a nutrition plan, while deconstructing the internalized diet-culture messaging that has caused me so much harm in the past.

  • I have been working with Madeline Barker for over a year.  Her program emphasizes self-care, good nutrition and weight loss.  I have lost over 30 pounds.  I am impressed with Madeline's support and strategies to help me achieve success.  My progress is not just measured in weight loss, but also in positive changes, building new habits and a positive self-worth.  Madeline's positivity is helping me become proud of my achievements and have a positive outlook.  

    I look forward to achieving my goals with Madeline's advice and assistance.

  • I’m more confident at the grocery store and at restaurants because I have clear guidelines I can follow (or, consciously choose not to follow, when there’s something I really want.)

    I’m more satisfied with my meals. My cravings have leveled out. I don’t feel like I’m not getting enough to eat. I’m in a better mood and feel better in my body.

    Madeline is knowledgeable, supportive, encouraging, adaptable, and such a sweet person. I truly love working with her. I highly recommend giving her a try!
