East Valley Naturopathic Doctors opened in Mesa in 2008. Seven licensed clinicians, one in-house clinic, and a framework — EVND Foundations — refined across thousands of complex cases.
EVND Foundations is the framework our doctors have refined over 18 years of practice. It treats chronic disease, optimization, and acute illness as an individual journey — guided by labs you can read, decisions you understand, and a plan that adjusts as your body does.
A 60–90 minute intake with one of our NMDs — the kind of conversation you have not had with a doctor before.
Functional labs, imaging where warranted, and conventional workups. We measure before we treat.
Your NMD builds a phased plan with clear milestones — diet, supplements, therapies, prescriptions.
We re-test, re-tune, and stay with you.
Suite 110 on Southern Avenue in Mesa: the front desk, the waiting room, and the treatment rooms. The IV suite, regenerative injection room, HBOT chamber and neurofeedback lab are all under one roof.
All servicesOur doctors are board-licensed NMDs in the state of Arizona, plus licensed massage, nutrition and skincare practitioners.

“Dr. Jason Porter has been so incredibly helpful in my health journey! He is very knowledgeable and you can tell that he is passionate about his job and helping his patients. He is proactive in recommending helpful tests, treatments, and more. I can tell that he cares about me as a patient and I appreciate his overall expertise. I highly recommend EVND and Dr. Porter!
“Dr. Porter and staff have been amazing. Dr. Porter is extremely thorough and takes the time to ask questions and listen intently to my responses. I do not feel rushed when I meet with him. I know I am being heard and I know he is trying to find the cause of the symptoms and not mask them with prescriptions. He worked a miracle on my piriformis muscle a few years ago through PRP. I highly Recommend!
“I’ve been a long time patient of Dr. Porter and EVND and I without hesitation highly recommend them. Dr. Porter is a genius and is always helping me sort out difficult chronic health issues all while being positive and professional!
“I have been a patient of Dr. Jennifer Nevels since 2019 and she has been the best doctor I’ve ever had! She truly took all the necessary time to listen to my symptoms and worked with me to get me feeling well. She explains everything well and goes through all your lab work results in detail. She is amazing and I highly recommend her as a doctor. The staff at East Valley Naturopathic Doctors is also amazing, kind, and so helpful. They are an excellent team!
“Dr. Nevels is truly the kindest, most compassionate, and knowledgeable doctor I have ever had. She listens to her patients and truly cares about them. BEST female doctor for any patient, but especially women, as she specializes in women’s health! You won’t regret going to her!
“Dr. Nevels saved my life! My life was declining fast. For years other doctors gave me suggestions on what I could do, or what it might be. Nothing worked. It was when I saw Dr Nevels did I get the answer to my declining health. I had intestinal Parasites!!
No other doctor considered parasites but Dr. Nevels. So blessed to have her as my doctor! Thank you for giving me my life back!
