The Sage Doctors

  • Herbs Topview
  • Mortar1
  • Stackrocks Lavendar
Both doctors graduated from the National University of Natural Medicine (NUNM) in Portland Oregon and moved to Colorado in 2002. Dr. Plummer and Dr. Koloski opened Sage Holistic Health together in January 2003. Their skills offer a unique blending of therapeutic modalities.

The doctors have a vision of building a community of healing practitioners at Sage Holistic Health.

The doctors refer their patients to each other for specific treatments, as well as to other health care professionals when appropriate in order to provide the highest and most appropriate level of care for each individual. They have worked diligently to develop an extensive referral network among other holistic health care practitioners as well as allopathic health care providers.

To support the community, the doctors donate to and annually support the Loveland Youth Gardeners.  Both doctors are providers for the Hope Lives! Breast Cancer Support Center and give nutritional consultations and acupuncture treatments to foundation clients going through cancer treatment.

  • Dr. Dee--I find myself writing again to say, "THANKS." I can't tell you how appreciative I am for the wonderful care you gave my brother. He is such a special person in my life, and your knowledge and help will have a big impact. Thank you for your excellent care. ~V.T.
  • I want to thank Dr. Plummer for treating my neck, hand and wrist pain. The Myokinesthetic System is a success! Since my last treatment a few weeks ago, I have been able to do activities such as gardening, vacuuming, scrubbing floors, blow-drying my hair, cooking, carrying boxes, making beds, etc., all of which used to result in pain. Driving the car even resulted in pain! Interestingly, I have been feeling arm strengthening instead! ~T.A.
  • Thank you for your tender loving healing these last several weeks. I can't tell you how much comfort you've brought me while healing from this pneumonia; from the (luxourious) hydrotherapy sessions to the tailor-made herbal tinctures. It's been a well thought out treatment which has made all the difference both psychologically and physically to my "mind-body." From my heart I say--NAMASTE. ~Julie
  • Just wanted you to know that your caring and thoughtful attention to my many health issues is greatly appreciated. It is reassuring to know that you both are doing your best to bring me some relief and that my questions, comments and opinions matter. Keep up the great work! ~Mary
  • I have never experienced such a thorough approach to medicine. The doctors at Sage Holistic took the time to discuss a range of health-related topics, from diet and exercise to what's happening in my life, careful to incorporate both traditional and holistic approaches. My symptoms presented a rather challenging diagnosis. Dr. Dee was able to "put the pieces together", much like a detective! I've been amazed at how much I learn each time I visit Dr. Dee and Dr. Plummer! ~Paula
  • Taking my family to Sage Holistic Health is the best decision I have ever made. The doctors are so warm and caring and have really made a difference in my life. ~Suzy
