Stefany Testerman (formerly Carstensen), FNP-C, RYT, IFMCP
 
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.

Natalie Duperreault-Rohde, AGACNP-BC

 

Natalie Duperreault-Rohde is an adult gerontology nurse practitioner who recently earned a Master of Science in Nursing from the University of Northern Colorado because she wanted to have a place in the world of Functional Medicine. Through experiences of her own, she believes there is more to health than Western medicine alone can offer and that a blend of integrative techniques and science driven medicine is the key to wellbeing.  She received  a Bachelor of Science in Nursing from the University of Colorado in 2003.  Her nursing career has been primarily in the Intensive Care Unit setting; she has also worked in Interventional Radiology and in outpatient surgical settings.  Natalie is particularly interested in chronic disease, gut healing, and managing  cardiovascular disease risk factors through lifestyle and diet modification.  She is board certified through the American Nurses Credentialing Center (ANCC). 

Natalie is originally from Canada and naturally loves winter in all its glory (down hill skiing, snowshoeing, building a snowman, and a roaring fireplace).  Cooking plant based foods and baking artisanal sourdough bread is a passion of hers.  She loves the outdoors and music in all its many forms.
