Welcome and thank you for your interest in Optimal Terrain! We are your resource for all things related to integrative oncology in treatment, prevention, and support for the cancer journey and beyond.

We recognize the overwhelming amount of information at your fingertips, suggestions from well-meaning family and friends, and the constant stream of media input further adding to the stress and confusion of being met with a diagnosis of cancer. Where do I begin? What is the next step? Who should I see? What can I do to avoid being a statistic? How do I prevent recurrence? How do I educate my family on how to lower their risk of cancer?

Instead of focusing on the cancer site and cell, we focus on establishing your “Optimal Terrain,” making it inhospitable to the cancer cell. We create a road map of the best options available to you given your individual and unique metabolic process.

Optimal Terrain is forging a new definition of health in a cancerous process.

2016 Upcoming Events


In my opinion, there are areas of medicine that need special training and full-time focus. Oncology is such an area. I live in a rural area and am the only resource in my county for integrative oncology. However, I also handle all the other needs of my patients as their primary care provider. I am very grateful that I have Dr. Nasha Winters as a trusted consultant. Though I have attended many conferences focusing on oncology, and have assisted in many protocols over the years, I have found that having Dr. Nasha Winters as a resource to help develop the most powerful treatment strategies for my oncology patients is invaluable. The depth and detail that she can add is astounding and incredibly inspirational to my patients (and to me). I know that my patients are happier having her on board. Clearly, so am I.
Holly Christy, ND, LAc
Practitioner / Element 7 Wellness
I have known and worked with Dr. Winters over the last 9 years both personally and professionally with mutual patients. The integrity and clarity that she brings to the table are remarkable. Her thoroughness and ability to sort out fine details in peoples health conditions are a true gift. I have not seen anyone who looks at the overall picture of someone's health as well as she does. She is a constant student and is continually on the cutting edge of what is possible for the people she serves. She has raised the bar of what true healthcare can look like.
Dr. Clayton Sullwold, D.C., K.C.S.C., C.A.C
Practitioner / Atlas Specific
One of my colleagues is a naturopath who has worked wonders for women with ovarian cancer. Her name is Dr. Nasha Winters. She consults via Skype. She has a very active practice so it may take some time to get an appointment. If you think you might be interested in working with her then reach out ASAP. Optimal Terrain Consulting Bonus: She's very supportive of the ketogenic diet and other lifestyle improvements.
Miriam Kalamian, EdM, MS, CNS
Practitioner / Dietary Therapies
Nasha Winters is generous in both heart and deed. She has committed her personal time to events organized by Klose Training to help educate health professionals and patients alike. Her message – backed by science and treatment success with her own patients – is one that is rare in the mainstream health care world today, i.e. that people can take responsibility for aspects of their own health through the choices they make in their diet and lifestyle. The information she imparts has been met with resistant by many conventional practitioners but because of Dr. Winters’ courageous persistence, her important message is now winning over physicians and therapists, to the benefit for their patients. Dr. Winters’ passion is contagious and motivating.
