Dr. Kate Sage, NMD

Dr. Kate Sage, NMD

As a little girl in Northern Wisconsin, Dr. Kate Sage’s favorite game was playing doctor. Raised in a family of doctors, she always knew in her heart that practicing medicine is where her footsteps would take her.

At the University of Puget Sound in Tacoma, WA, Dr. Kate learned more about medicine, including the challenges of being an MD.  Weighing both sides, she opted instead to get a degree in Foreign Language and International Affairs.  Her senior year however, she met her first Naturopathic Doctor and the stars suddenly aligned. Eventually, Dr. Kate attended the National College of Naturopathic Medicine (now called the National University of Natural Medicine) in Portland, Oregon.  In 2009, her dream came true and she became the doctor she always wanted to be.From that point, she worked at a naturopathic family practice in Prescott, AZ.  Through the years she had two beautiful girls and began to enjoy more and more working with children in her practice.  In time, the stars made themselves clear that she would be happiest working with kids ALL of the time.

More work and schooling led to Dr. Kate to becoming a specialist in naturopathic pediatrics.  She is delighted to be living the dream at Blue Oak Clinic where she helps babies, children, and teens grow healthily and live as happily as possible. When she is not doctoring, she loves to run and swim and dance and play music, especially with her husband and girls.

She attended Southwest College of Naturopathic Medicine (SCNM) in Tempe AZ.  She gravitated toward herbal medicine, acupuncture, hydrotherapy and nutrition.  During clinical training she completed shifts in primary care and elected to train at a variety of community outreach clinics in the Greater Phoenix area (Southwest HIV Center, domestic violence shelter, Roosevelt Elementary community clinic and substance abuse detoxification centers.)  As she learned about traditional Nature Cure, she joined the Naturopathic Society and helped return the student-organized Naturopathic Gathering to SCNM.
