Foundational Medicine & Education

"Working with Dr. Scheeler has been a truly powerful experience for me. Not only had I had years of being let down by the medical system before our journey together began, but I had never had an experience where I felt truly listened to by a medical professional. I walked away from each appointment feeling seen by her and being fully confident in the plan that we had created together. Each time I was comforted by her abundance of knowledge as well as her compassion and always felt like I was in the best of hands. Never have I felt so confident in a provider’s ability to help me decipher, prioritize and put into action the most important changes and strategies for me to live my healthiest and best life."

“Even though I’ve only worked with Dr. Claudia Bustamante for the last couple of months, the experience has already been truly transformational. From the very beginning, she has been present, accessible, and responsive—meeting urgent needs with compassion, patience, and expertise.

What makes her stand out is her holistic approach to care. She doesn’t just treat the symptoms—she works to address the root causes of my chronic illness, using every tool available to find thoughtful, personalized solutions. She’s knowledgeable, data-driven, and always focused on what we can do, which has been incredibly empowering.

Dr. Bustamante has made treatment options I once thought were out of reach a reality. She’s lifted me up during the most challenging moments and made me feel truly cared for—not just as a patient, but as a whole person.

I’m genuinely excited to continue this journey with her and feel hopeful about managing my condition in a way that honors my full self. I highly recommend.”

“Dr. Scheeler is kind, caring, super smart, and knowledgeable, and she made me feel seen and heard, 5/5 recommend”

"Hey, it’s Joel Sprechman with One Great Gut. I wanted to record a testimonial for Dr. Mark Davis. I’m blessed with one of the tougher cases of IBD, a blend of Crohn’s and Colitis,  and though I’ve been studying IBD for decades you just don’t know what you don’t know. After mixed results with many providers I’m now very selective whom I work with. Mark is an all-star, one of the reasons I still have my colon intact.  While using cost-effective tools I went from severe disease to remission while I was doing normally stressful things like public talks and an online product launch. I also successfully weaned off a  pharmatucial drug.  I wouldn’t hesitate to work with Mark again, he knows his IBD stuff extremely well.  If you’re thinking about who to work with next, give him a call. Mark, Thank You. I’m grateful to have had the opportunity to work with you directly."

"Dr. Claudia Bustamante has been treating me for the past three years, ever since I was diagnosed with Crohn’s disease. At the time, I was in poor health, experiencing frequent episodes of diarrhea and stomach pain.

Since I began receiving treatment from Dr. Bustamante, I’ve been doing very well. This is reflected in the results of the fecal calprotectin tests she regularly asks me to take, which have been consistently decreasing—my most recent result was 92.

Thank you very much, Dr. Bustamante, for your accurate diagnosis and effective treatment."

“I came to [Dr. Natalie] seeking answers for my gut issues after trying several doctors without success. From the start, the detailed questionnaire I received was more personal than any experience I've ever had. That told me all I needed to know.. Dr. Natalie was incredibly attentive, providing realistic solutions while also explaining the whys and hows. I felt optimistic and empowered to apply what I learned toward my healing and I would highly recommend [Dr. Natalie] to anyone looking for personalized and attentive care.“

"I had decided to come off medication for Ulcerative Colitis and heal my body… Dr. Natalie is super knowledgeable about UC and was able to put my mind at ease when I was experiencing fear and anxiety about healing my body… In about 6 months, I was completely symptom free. It's now been over a year and I have zero issues… I would highly recommend her to anyone healing their bodies or currently dealing with symptoms from IBDs."

"I went to Dr. Mark Davis several years ago with questions about the possibility of FMT for treating my various issues. I quickly learned that not only is he incredibly knowledgeable about FMT in particular and gut health in general, but is also one of the most personable and down-to-earth doctors I've ever had the pleasure of dealing with. Bowel issues can be a very awkward subject to discuss with anyone, but I always felt at ease with Dr. Davis. The treatments he prescribed have made a huge, positive impact on my life. I am so grateful for having found this doctor!"

“I remember when I was diagnosed with h.pylori and was worried about how my body would react to the antibiotics. My wife and I thought it be best if we went the holistic route and that’s where [Dr. Natalie] came in. We connected and had our first call. I knew I was in good hands. Dr. Natalie is awesome! I can’t thank her enough. She guided me and was always available to talk things through with me. Her expertise and knowledge helped me get positive results. At no point did I feel judged or mistreated. I felt comfortable and knew I was in a safe space. I definitely recommend everyone to her.”

“Dr. Scheeler was absolutely the doctor that I was looking for. She was attentive and focused during our consultation and made sure to ask lots of questions to understand the full picture, making connections that I hadn’t been able to make. No matter what I was having a problem with, she was able to effectively create a treatment plan for me and would also provide additional tips and ideas for my own benefit.”

“Dr. Claudia has been a fabulous resource for me the past couple of years. Her naturopathic background in gastroenterology has helped me work through Eosinophilic Esophagitis, Gastric Intestinal Metaplasia, and two Diverticulitis flares. Her approach is very supportive and calming. Dr. Claudia does an excellent job summarizing our visits and providing menu options.

She is an essential resource for me as I work to get to root causes and healing.”
