What a Naturopathic Doctor in Phoenix, AZ Does

Arizona licenses naturopathic medical doctors to examine patients, order lab work and treat with natural therapies first. Dr. Yosef uses that training to find the root cause of a long illness, correct the imbalances behind it and lower the toxic load that keeps it going.

Our one office is on East Bell Road in Scottsdale, a drive up the Loop 101 for most Phoenix patients. Testing, IV therapy and injections all happen there.

Conditions We Treat

Our clinicians see illness that is often missed when routine results come back normal.

Chronic Fatigue Syndrome

Exhaustion that rest does not fix is one of the illnesses both of our clinicians treat. We test for nutrient gaps, adrenal strain and toxic overload that can drain energy.

Plans often pair orthomolecular dosing with IV therapy for energy and adrenal support.

Specialized Testing Before Any Plan

Naturopathic doctors do run blood work. We add assessments a routine checkup rarely includes, so your plan rests on measurements.

  • Blood and Urine Panels

    Customized tests chosen for your symptoms.

  • EAV Testing

    Electrodermal readings at acupuncture points.

  • Thermography

    An infrared map of heat patterns across the body.

  • Heart Rate Variability

    A reading of how your nervous system handles stress.

FAQ About a Naturopathic Doctor in Phoenix, AZ

Does Arizona recognize naturopathic doctors?

Yes. Arizona licenses naturopathic medical doctors, who use the NMD credential. Dr. Isaac Yosef practices as an NMD from our Scottsdale office, and our team also includes Lina Kay, PA-C, MS.

Do naturopaths do blood tests?

Yes. We order customized blood and urine tests chosen for your symptoms, and we add assessments that a routine checkup rarely includes, such as EAV testing, thermography and heart rate variability. Your plan is built from those results.

What is the difference between a naturopathic and a holistic doctor?

Holistic describes a philosophy that many kinds of practitioners share. A naturopathic medical doctor is a licensed clinician trained to diagnose, order labs and treat with natural therapies first. Our care is holistic in approach and medical in method.

How do I find a good naturopathic doctor in Phoenix, AZ?

Check that the doctor holds an Arizona NMD license, ask which conditions they see most often, and ask what testing guides their plans. Dr. Yosef works mainly with chronic, hard-to-diagnose illness such as chronic fatigue, Lyme disease and mold illness.

Can I keep my primary care doctor?

Yes. Many patients keep their primary care doctor and see us for the chronic problems that have not resolved. Naturopathic care can run alongside the care you already receive.

How much does a naturopathic doctor cost?

Cost depends on the testing and therapies your plan includes, so we go over it with you before anything starts. Contact our office and our team will explain the options for your situation.
