Who We Are

Holly Deffert, RN Owner/Founder

Holly Deffert, RN- Colorado native, nurse turned natural healer, life long student, planet protector, lover of life! My greatest passion is helping others! My approach to healing has been influenced by conventional medicine, 10 years of emergency department nursing as well as the study of functional/integrative/regenerative/energy medicine and the teachings from ancient plant medicine philosophies.

I became frustrated with our current health care system after watching many people suffer unnecessarily.  10 years ago I started a juice cleanse that opened my eyes to a whole other world of Holistic Healing, one not openly shared in western medicine.  

I began seeking out like-minded health practitioners and focusing my attention more on holistic health. I believe in treating the mind, body and spirit of each person, not just symptoms of disease. This ancient approach to health considers how each person interacts with his or her environment. People accept responsibility for their own level of well-being – everyday choices are used to take charge of one’s own health. The goal is to achieve maximum well-being, where everything is functioning at its optimal level. True healing can be attributed to personal awareness, life style changes, mindset reprogramming, self acceptance, healing from personal traumas and a team of skilled practitioners.


As one of of the owners and founders of The Earth is Calling Natural Remedies, I am so excited and honored to be a part of your healing journey.  I am looking forward to servicing the Denver/Evergreen area with a variety of stem cell therapies, ozone therapies, biophotonic therapy and other nutritional IV support as well as the best super food nutrition on the planet.

I became a Nurse over 20 years ago, and initially, I worked in the inpatient hospital setting, in a variety of settings including oncology, Bone Marrow Transplant, ICU, Labor and Delivery and a Medical Surgical unit. I rapidly became frustrated by the fact that so many of the patients I cared for struggled with chronic diseases that were often related to choices in diet and lifestyle. Additionally, the traditional Western medical system was not focused on healing, it seemed focused on treating symptoms without actually improving patient health.  After I became a Nurse Practitioner in 2008, I dedicated my practice to helping patients improve their lifestyles and nutritional approaches, while working to empower patients with education and supportive self care strategies.  


My approach with patients is patient centered and compassionate. My goal is to partner with you, and to offer you tools, education and support so that you can feel and be your very best. I utilize Functional Medicine principles in order to truly get to the root cause of your symptoms, and together, we will develop a comprehensive treatment plan that is effective, manageable and focused not just on treating your symptoms but on restoring balance to your body.  


I graduated from the University of Colorado College of Nursing with a Bachelor's Degree of Science in Nursing in 2000. I returned to school a few years later, and graduated from my alma mater with a Master's Degree in Nursing in 2008 and became Board Certified as  a Family Nurse Practitioner. Finally, out of a desire to deepen my own spiritual and yoga practice, I completed a 200 hour Yoga Teacher Training with Whole Yoga in Denver Colorado in 2013. Additionally, I have continued my education in the fields of Integrative Medicine and Functional Medicine with the Institute of Functional Medicine on an ongoing basis, and have the honor of being granted the designation of Institute for Functional Medicine Certified Practitioner (IFMCP) in December 2019.
