Chikako Harper

N.D., L.M.T.

Naturopathic Family Physician


I believes illnesses are manifestations of internal imbalances. My goal is to identify and treat the underlying cause rather than just treating symptoms. I use a unique, integrated approach, combining cutting-edge Western medicine with the healing arts of natural medicine to promote the body’s innate self-healing ability.

I build a partnership with each patient. I’m an expert on naturopathic medicine, but you are an expert on your own symptoms. We will collaborate and discover the root cause. We will work together to fine-tune your treatment plan and restore your health. Let’s work as a team to optimize your health. We’ll build a strong foundation so that you can focus and achieve your life goals!

My areas of specialty include: skin conditions, allergies, diabetes, hypertension, women’s health, breast cancer support, thyroid disorder, adrenal fatigue, migraine, GI conditions, weight loss, acute and chronic pain, and mood disorders.  Dr. Chikako is also a Mood Specialist, and the only practitioner in Oregon certified by Julia Ross, author of “The Mood Cure.

As your primary care doctor, I also offer routine health check-ups and women’s annual exams.

There is always a reason behind your illness.
Let’s get to the root cause.

I became an Oregon board-certified naturopathic doctor as part of my own health journey. I suffered head-to-toe severe Atopic Dermatitis (a.k.a. chronic eczema) for over 20 years. I was told there was no cure, and my doctors treated my symptoms with corticosteroid. We had to continually increase the dosage in order to control my eczema. I thought there must be a better way, so I quit my executive job, left Japan, and enrolled in the National College of Natural Medicine–the most authentic and comprehensive naturopathic medical school in the world. Overcoming my own chronic illness ignited a passion in me to help others reclaim their health and their lives.


I am also an Oregon Licensed  Massage Therapist  and a two-time breast cancer survivor.
