Having unexplained symptoms or constantly being told you have "unremarkable" labs?
It's time to look deeper. Conventional medicine excels at acute care. It was never designed to investigate the slow, cumulative, hard-to-name patterns that define chronic illness. The GI Map gut health test takes the first step in investigating root causes.

Why the GI Map test?
Approximately 80% of the body's immune system resides in the gut. That single fact reframes almost every chronic symptom pattern — fatigue, brain fog, hormonal dysregulation, skin conditions, mood instability — as potential downstream consequences of a compromised gut environment. All healing and wellness begins in the gut, and its importance is often overlooked in conventional medicine.
The gut is your immune command center
The gastrointestinal tract houses the largest concentration of immune tissue in the body — the gut-associated lymphoid tissue (GALT). When the microbial environment is disrupted, immune regulation breaks down. Chronic inflammation, autoimmune reactivity, and systemic dysfunction often trace back to here.
Dysbiosis drives symptoms far beyond digestion
An imbalanced microbiome (dysbiosis) doesn't just cause bloating or irregular bowel movements. Pathogenic overgrowth, parasitic infection, and fungal colonization can drive neurological symptoms, hormonal disruption, nutrient malabsorption, and persistent fatigue — none of which will show up on a standard blood panel.
You can't fix what you haven't measured
Generic gut protocols like elimination diets, probiotic supplements, digestive enzymes,etc. address symptoms without identifying the underlying terrain. The GI-MAP provides the data to understand exactly what's present, what's missing, and what the body actually needs to restore function.
Gut healing creates a foundation for everything else
Hormonal balance, cognitive clarity, immune resilience, skin integrity, and sustained energy are all downstream of a healthy gut. Attempting to address these systems in isolation without first assessing and restoring gut function, is working against the body's own architecture.
If you don't know what's happening in your gut, you don't yet have the full picture. The GI-MAP is where that investigation starts.

What clients are saying.
Real experiences from people who went looking for answers.
"After hearing horror stories of women in menopause, I wanted to do everything I could to minimize symptoms as I neared this transitional phase. I wanted a more natural way to not only understand what was going on with my body, but to help it transition with more holistic methods. I was so glad to find Mary! The GI-Map test and the protocol designed by Mary helped tremendously to understand the power behind my gut health and it's connection to my state in life. I sleep better, feel better and have more energy!"

"We all hear about gut health but have you really ever had your gut tested? I had not until now. The things I found out were so informative and put me on a path to health and wellbeing. I even found out I had a parasite! Yuck! Mary gave me the results and suggested a supplement regime that would help clear things up and take care of a few other things. After finishing things up, I have never felt better! I thought I was feeling great before but this was another level. And now I am confident that I am taking the correct supplements that will allow me to have the quality of life that I am looking for as I continue to get older."

"The self-directed model was exactly what I needed. I didn't have time for weekly appointments. I ordered the kit, completed the intake, and had my report within a few weeks. The whole process was seamless."

"Working with Mary has been a truly positive and transformative experience for our family. Our daughter had been struggling with weight gain, ongoing fatigue, and a general sense that she was not feeling like herself. Mary took the time to carefully listen, evaluate the bigger picture, and explore potential contributing factors that had not been addressed through traditional approaches. Her thoroughness, compassion, and commitment to finding answers made all the difference. Mary approached our daughter's care with patience and persistence, never settling for a surface-level solution. Through her guidance and support, we chose specific tests to run and was able to narrow down issues to then make meaningful improvements in overall health. For my daughter, this meant gaining a renewed sense of confidence that positively influenced every aspect of her life. We are incredibly grateful for Mary's dedication and the individualized care she provided. Her willingness to look deeper, ask thoughtful questions, and truly invest in our daughter's journey set her apart. We highly recommend Mary to anyone seeking a practitioner who takes a comprehensive, compassionate approach and genuinely cares about helping people feel their best."

"What I appreciated most was how thorough and educational the whole process was. Mary doesn't just hand you a report — she translates it into something you can actually understand and act on. I came in skeptical and left with a completely different perspective on what it means to take care of your health. The results spoke for themselves. I only wish I had done this sooner."
