Naturopathic Care for Fountain Hills, AZ Patients
A naturopathic doctor asks why your symptoms started, then treats that cause with natural therapies first. In Arizona, naturopathic medical doctors hold the NMD title and are licensed to examine patients, order lab work and diagnose illness.
Dr. Yosef practices as an integrative physician. Much of his work is with chronically ill patients whose illness has been hard to pin down, such as chronic fatigue syndrome and Lyme disease, where he looks for the underlying imbalances and toxic overload that keep them unwell.

Conditions Our Naturopathic Doctor Treats
Many patients come to us after years of normal-looking labs and no clear answer.
- Chronic fatigue syndrome and long-running exhaustion
- Lyme disease and other elusive illness
- SIBO, SIFO and IBS
- Histamine intolerance and inflammatory disorders
- Mold illness and environmental exposure
- Hormone imbalance, joint pain and stubborn weight
Normal Labs Are Not the End of the Search
A standard panel can come back clean while you still feel unwell. We read every result beside your history and symptoms, so your plan follows the cause rather than a single number.

Naturopathic Doctor FAQ for Fountain Hills, AZ
Can a naturopathic doctor prescribe medicine in Arizona?
Yes. Arizona licenses naturopathic medical doctors, who use the NMD title, to examine patients, diagnose illness and prescribe within the scope state law sets. Our plans lead with natural therapies such as homeopathic, herbal and nutritional care, and medication is part of the conversation when your condition calls for it.
Do naturopaths do blood tests?
Yes. We order customized blood and urine tests chosen around your symptoms, along with allergy testing that guides nutritional counseling. We also offer EAV testing, thermography and heart rate variability, and we read every result together with your history.
What is the difference between a naturopathic and a holistic doctor?
Holistic describes an approach, and anyone can use the word. A naturopathic medical doctor completes a four-year, graduate-level naturopathic medical program and holds a state license. Dr. Yosef is a licensed NMD who practices as an integrative physician.
How do I choose a naturopathic doctor in Fountain Hills, AZ?
Confirm the Arizona NMD license first. Then ask what testing they use beyond a routine panel, whether they explain the reason behind each therapy, and whether the team has experience with your concern, such as gut, mold or chronic fatigue illness.
How much does it cost to see a naturopathic doctor?
Cost depends on the testing and therapies your plan includes, so it differs from patient to patient. We go over fees with you at your consultation, before any testing begins.
Can I keep my regular doctor while seeing a naturopathic doctor?
Yes. Many patients keep their primary care doctor and add naturopathic care for problems that have not resolved. We review your past results so new testing adds to what is already known rather than repeating it.
