About My Guest

My guest for this episode is Dr. Jill Carnahan, MD.  Dr. Carnahan is board certified in both Family Medicine and Integrative Holistic Medicine. She completed her residency at the University of Illinois Program in Family Medicine at Methodist Medical Center and received her medical degree from Loyola University Stritch School of Medicine in Chicago. She received her Bachelor of Science degree in Bio-Engineering at the University of Illinois in Champaign-Urbana.  Dr. Carnahan moved to Boulder Colorado in 2010 joining medical partner, Dr. Robert Rountree. She opened her own practice, Flatiron Functional Medicine in Louisville CO to expand the services that she offers to her patients.  Dr. Jill Carnahan uses functional medicine to help you find answers to the cause of your illness and the nutritional and biochemical imbalances that may be making you feel ill. Functional medicine is personalized medicine that deals with root cause of disease instead of just treating symptoms.  Dr. Jill will search for underlying triggers that are contributing to illness through cutting edge lab testing and tailor the intervention to the specific needs of an individual. She may use diet, supplements, lifestyle changes or medication to treat illness but will seek the most gentle way to help the body restore balance.  She seeks to promote wellness and create hope, health and healing.  Dr. Carnahan walks her talk.  She is both a cancer survivor and recovered CIRS patient after she encountered mold in her practice.
