Natural Root Cause
Serving Delhi

Your energy is gone by noon. The brain fog makes simple tasks feel impossible. Your hormones are all over the place and you know something is off, but regular doctors keep running the same basic tests that come back "normal." In Delhi Township, people dealing with chronic health issues that mainstream medicine can't pin down need someone who digs deeper into root causes. When you search for the best alternative medicine practitioner near you, Natural Root Cause is who handles those calls.

Do not keep bouncing between specialists who only look at symptoms. Chronic health problems usually have multiple triggers: nutrient deficiencies, hormone imbalances, food sensitivities, or toxin buildup that standard blood panels miss. The fix requires advanced functional testing and personalized protocols, not one-size-fits-all treatments. Practices that handle complex cases year-round use comprehensive lab panels and IV nutrient therapy to address what your body actually needs. We run advanced diagnostics including food sensitivity testing and specialized panels, then design targeted nutrition and supplement protocols based on what your specific labs show.

Common Question in Delhi

Chronic fatigue and doctors can't find anything wrong

You've hit the wall that stumps most Delhi residents dealing with chronic exhaustion. Standard blood panels only check a handful of markers, missing the deeper imbalances that drain your energy day after day. Comprehensive functional testing looks at complete thyroid panels, nutrient deficiencies, food sensitivities, and hormone levels that basic labs skip entirely.

What Our Customers Say

★★★★★
I thank God every day for leading me to Keith for treatment. Over three months, I suffered from blood clots, extreme fatigue, autoimmune issues, vision problems, and widespread pain that kept getting worse. Multiple specialists couldn’t help me. A family member recommended Keith, and he truly changed everything. He took the time to listen without rushing, explained what was happening, and diagnosed me with Long COVID and vaccine injury. After starting treatment, I began feeling better within days and eventually returned to my normal self. Keith gave me hope from the very first visit. He is truly one of a kind and I believe he saved my life. I am forever grateful!

After struggling with a blood disorder that left me vulnerable to frequent infections and illness, I felt stuck and without real solutions. Everything changed when I met Dr. Austin. He took the time to truly listen, understand my symptoms, and clearly explain how a functional medicine approach could address the root cause of my condition. Today, I am healthy and feel like myself again, something I once thought was impossible. I believe that Dr. Austin saved my life.

I went to Root Cause because I could tell my body was changing, and meeting with Sara was exactly what I needed. She explained my bloodwork clearly, gave me helpful guidance without any pressure, and let me decide what was right for me on my own timeline. Within just two days of starting treatment, I noticed a difference—clearer thinking, steadier emotions, and confidence that I made the right decision for myself and my family.

Trusted Partners

Most Delhi Township families live in homes built between the 1970s and 1990s, spread across neighborhoods like Embshoff Woods and the areas around Delhi Park. If you've been dealing with chronic health issues that conventional medicine hasn't solved, you're not alone here. The stress of suburban life, processed food diets, and environmental toxins common to Hamilton County can create hormone imbalances, digestive problems, and fatigue that standard blood tests often miss. Natural Root Cause works with Delhi residents who need functional medicine testing and integrative treatments that address what's actually causing their symptoms, not just managing them.

Your Local Team

Keith Tenhundfeld
FNP

Keith Tenhunfeld's journey into medicine began in 1993, and from the very start he was drawn to something deeper than the standard model of care. Over more than three decades, he pursued nursing, advanced practice, and a wide range of integrative therapies — building the kind of well-rounded clinical perspective that comes only from years of genuine curiosity and hands-on experience. As a certified Family Nurse Practitioner, Keith has long believed that true healing requires addressing the whole person — body, mind, heart, and soul — not just the chief complaint. His patients often describe him as the provider who finally listened, and who gave them hope when no one else could.

Sara Aicken
PA-C

Sara Aicken is a Physician Assistant with 17 years of clinical experience and a genuine passion for care that goes beyond the conventional. A graduate of the Medical University of South Carolina's PA program, she has earned advanced certification in functional medicine and bio-identical hormone therapy through Worldlink Medical, and has brought healthcare to underserved communities in rural Alaska, Idaho, and on medical mission trips to Haiti, Africa, and South America. Sara excels at thinking beyond the surface — helping patients reclaim energy, balance hormones, and add real quality to their years. When she's not in the clinic, she's on her homestead in Harrison, Ohio, tending bees, chickens, and a garden alongside her husband and kids.

Trent Austin
MD

Dr. Trent Austin is a board-certified physician whose path to functional medicine began with a deeply personal wake-up call — when standard prescriptions for his own elevated blood pressure and cholesterol left him feeling worse, not better, he started asking better questions. Watching his parents navigate chronic illness through a system focused on managing symptoms rather than finding answers only deepened that resolve. Today, Dr. Austin blends his conventional medical training with a genuine passion for root-cause healing, specializing in chronic conditions like Alzheimer's, dementia, depression, and diabetes. He's a lifelong learner who believes the best medicine happens at the intersection of science, nature, and truly knowing each patient's story.
