Functional Nutritional Therapy Practitioner
Ready for a healthier path you can feel in your energy and see in your markers? You know food shapes your results, but the perfect diet evades you.
The truth is, the only perfect diet is a flexible food lifestyle that satisfies you with ease. For over a decade, Tam John, FNTP, has shaped Daisy Fields Company into a credible clinical resource.
We support adults, elders, and families—from children to teens—with foundational virtual nutrition leadership. Our practice specializes in nourishing gut health (digestion, IBS, leaky gut, food sensitivities) and reversing blood sugar imbalances (Prediabetes, Type 2 diabetes, insulin resistance).
While working safely alongside your medical team, we design an adaptable, data-driven self-care protocol tailored exclusively to your life.
Step 1: Schedule Your Free Insight Call
Start with a conversation. This is a dedicated virtual space for Tam to listen to your health goals, symptoms, and concerns. If you dislike online booking calendars, we have you covered—simply give us a call or send a quick message to begin. Book Your Insight Call or Call/Message Us Directly
Step 2: Co-Create Your Personalized Protocol
There is no one-size-fits-all diet. Together, we look at what you want to accomplish, what you have tried, and your unique daily schedule. Tam will present custom paths based on your timeline and resources, allowing you to choose the exact clinical testing or nutritional therapy framework that feels right for you.
Step 3: Meet Virtually on Your Terms
Once we agree on a timeline, you will receive an invoice with flexible secure payment options. Whether you choose comprehensive testing interpretations or ongoing functional therapy consultations, we will meet via Zoom—feeling exactly like we are sitting across the kitchen table from one another.

Health Made Yours: Client Transformations
A Clear Path Forward: From Chronic GI Pain to Vibrant Health
“For years, I suffered from a constant bellyache, food sensitivities, and the inability to keep food down—even my early colonoscopies revealed no answers. The chronic pain was affecting my life and my family. When I found Tam, she treated me like a real person. She looked at my unique foundation, helped me uncover the root cause of my pain points, and taught me exactly what to eat to support my body. I finally achieved a healthy weight, my energy is back, and I feel incredible!”
Putting the Puzzle Pieces Together: True Data-Driven Personalization
“After 30 years of trying to find the right eating plan and working with many health professionals, I still lacked the consistent results I was searching for. Tam successfully put the puzzle pieces together for me. Her data analysis skills and advanced clinical tools—including Hair Tissue Mineral Analysis and Nutrigenomix® Testing—allowed her to look at my whole wellness picture. She designed a sustainable, food-first lifestyle plan that is easy to implement into my day-to-day life.”
Measurable Results: Reversing Metabolic and Blood Sugar Imbalances
“I am absolutely thrilled with my results—my A1c dropped from 6.8 to 6.1 in just three months! After sitting in the high 6s for years, Tam’s guidance helped me make sustainable nutrition changes that led to this massive improvement in my health. Even my doctor noticed the shift right away. Tam showed me how to build a personalized, realistic plan that completely works with my life without feeling like a restrictive diet.”
