What is the difference between a holistic doctor and a naturopathic doctor?
Holistic describes an approach that looks at the whole person, and many kinds of practitioners use the word. A naturopathic doctor is a specific licensed profession trained in medical sciences along with natural therapies such as botanical medicine, homeopathy and clinical nutrition. Dr. Yosef practices as an NMD, so a holistic outlook comes with a medical workup.
Does Arizona recognize naturopathic doctors?
Yes. Arizona licenses naturopathic physicians, who practice under the NMD title. When you choose a naturopathic doctor in Mesa, AZ or nearby, look for that licensed NMD credential.
Do naturopathic doctors do blood tests?
Many do, and we use them routinely. Alongside customized blood and urine tests, we offer EAV testing, thermography and heart rate variability. Which tests you need depends on your symptoms and history.
Can a naturopathic doctor help with Lyme disease or mold illness?
These are among the conditions our team treats most. Dr. Yosef works with chronically ill patients, including those with Lyme disease and chronic fatigue syndrome, and Lina Kay, PA-C, MS, has extensive experience with mold illness. Care starts by identifying underlying imbalances and toxic overload.
How is IV therapy used in naturopathic care?
IV therapy delivers nutrients and other compounds directly into the bloodstream. Our formulas are chosen for a purpose: immune support, anti-inflammatory care, detoxification, antibiotic, antifungal or antiviral support, adrenal support or energy. Orthomolecular IV dosing is matched to deficiencies found in your testing.
How much does a naturopathic doctor cost in Mesa, AZ?
Cost depends on the testing and therapies your plan includes, so it varies from patient to patient. We review costs with you at your consultation, before any testing or treatment begins.
