Treating The Underlying Disease

Integrative Cancer Medicine

Our approach involves not only treating the disease- the main focus of modern oncology- but also striving for improved quality of life through a combination of ancient wisdom and modern science. This is true integrative cancer medicine.

What Cancer Patients Need

Compassionate Care

We focus on the total picture of how our patients are doing, in all aspects of their lives. We offer a wealth of resources, close guidance, and comprehensive, common sense integrative/alternative treatment approaches.


Ancient wisdom and modern science

Integrative/Alternative Cancer Medicine is about intelligently synthesizing modern oncology with the most innovative, effective, and well-researched therapies in natural medicine.

Our goal is to provide care that is individualized to each patient, in a friendly, welcoming environment that supports wellbeing. This approach involves not only treating the cancer itself (primary focus of modern oncology), but also striving for optimal health.

Why Do A Cancer Consultation with Dr. Zieve?

  1. To have someone hear your cancer story in a non-rushed way.
  2. To receive guidance as to how best to work with your surgeon or oncologist.
  3. To be evaluated thoroughly through tests rarely done by oncologists.
  4. To receive a comprehensive integrative treatment protocol that is individualized to you–your quality of life concerns, your biological terrain, and your cancer itself, rather than just a chemo schedule.

Modern oncology is becoming more and more complicated by the day, which makes it more important than ever that you, as a patient, be able to sort through the often-conflicting information about cancer and its treatment to find the approach that’s best for you. I am here to help!

    Patient Reviews

    From the minute I met Dr. Zieve, I felt an unexpected ease. He is calm and patient, willing to answer all questions, and is genuinely interested in how his patients are doing, both physically and psychologically. He was the first doctor I encountered since my colon cancer diagnosis who did not talk down to me or make me feel like I was wasting his time. I've been working with him since 2017, and have recommended him many times. He has a wealth of knowledge about a variety of treatment approaches, and he considers your whole system, not just your cancer. He saw me as a person, not a diagnosis, and I'm very grateful to have found him.


    I came to see Dr. Zieve about 3 weeks after being diagnosed with stage 3 metastatic melanoma. It had spread from hundreds of subcutaneous tumors into my stomach, liver and bones. My regular oncologist was having a hard time authorizing the Braf + pharmaceutical drugs I needed and my condition was worsening daily. I believe that the vitamin C IV's I received saved my life by slowing down the disease process long enough to get the Braf inhibitors. Dr. Zieve also optimized my ability to recover with an array of herbs, mushrooms and other supplements to fight the cancer. He also was in direct contact with my oncologist in Sedona and as a team they insured my survival and quality of life I still enjoy today.


    COVID-19 Policy: Because of the severity of this pandemic with its many variants, and because there is so much we do not know, we ask when you come to the office to see Dr. Zieve, that you wear a mask that covers both your mouth and nose. This is mandatory even if you have already received a vaccine. Thank you for your cooperation.
