What a Naturopathic Doctor in Chandler, AZ Looks For
A naturopathic doctor asks why you got sick, not only what to prescribe. Our patients often carry illness that has been hard to pin down, so we look for underlying imbalances and toxic overload, then treat those with natural therapies matched to your test results.
Health Concerns We Treat
Most patients come to us after months or years of symptoms that standard care has not explained.
Chronic Fatigue
Exhaustion that rest does not fix is one of the conditions Dr. Yosef sees most. We test for nutrient gaps, hormone shifts and toxic load that can drain energy.
We may use: orthomolecular dosing, IV therapy for energy and adrenal support, herbal care.
Lyme Disease
Lingering, shifting symptoms after Lyme disease are part of the elusive illness our team focuses on. We look at immune function and inflammation together.
We may use: IV therapy with antibiotic, antiviral and immune support aims, homeopathic remedies.
SIBO, SIFO and IBS
Bloating, pain and unpredictable digestion are Lina Kay's specialty. She treats gastrointestinal disorders such as SIBO, SIFO and IBS.
We may use: herbal protocols, dietary counseling based on allergy testing, targeted supplements.
Histamine Intolerance
Flushing, headaches or reactions to food can point to histamine intolerance. Allergy testing shows which foods to change and which to keep.
We may use: nutritional counseling, homeopathic and herbal care, anti-inflammatory support.
Mold Illness
Symptoms tied to mold and other exposures fall under our environmental medicine work. We aim to lower toxic overload while supporting the body as it recovers.
We may use: detoxification IVs, antifungal support, orthomolecular nutrients.
Joint Pain
Painful joints can often be treated without surgery. Regenerative injections and in-office devices target pain and inflammation directly.
We may use: PRP and Prolozone injections, the Avacen and the Biomodulator.

Naturopathic Doctor FAQ for Chandler, AZ
Does Arizona recognize naturopathic doctors?
Yes. Arizona licenses naturopathic medical doctors, who use the NMD title after completing a four-year naturopathic medical program and passing board exams. Dr. Isaac Yosef is an NMD, and Lina Kay is a certified physician assistant.
Do naturopathic doctors order blood tests?
Yes. We order customized blood and urine tests chosen for your symptoms, and we can add allergy testing, EAV, thermography or heart rate variability when your case calls for them. Results guide every part of your plan.
What is the difference between a naturopathic and a holistic doctor?
Holistic describes an approach, and many kinds of practitioners use the word. A naturopathic medical doctor holds a state license and is trained to diagnose and treat, using natural therapies first. Our care is both: licensed and whole-person.
How do I choose a naturopathic doctor in Chandler, AZ?
Check for an Arizona NMD license, then look for a focus that matches your concern. Ask what testing the office runs and whether the plan is built on your own results. Our team focuses on chronic, hard-to-name illness and on gut and environmental conditions.

Yes. Many patients keep their primary care physician and specialists while they see us. Share your current medications and records so your natural plan fits alongside your other care.
What does naturopathic care cost?
Cost depends on the testing and therapies your plan includes, so it varies from patient to patient. We explain what your plan involves before treatment starts.
