About Dr. Katie Lee
Dr. Katie Lee is a dentist, author, and speaker whose work centers on oral microbiome science and oral-systemic health. She has incorporated saliva testing into clinical care since 2012 and is known for making complex microbial data useful in the dental chair, helping dental teams connect oral bacteria and inflammation with whole-body health and turn those findings into clear, practical care.
Dr. Lee is the Founder and CEO of Collective Health Society, an integrated biological dental and functional wellness clinic in Centennial, Colorado. The practice brings oral microbiome testing, biological dentistry, functional wellness, and airway and sleep care together under one roof, with the mouth treated as a gateway to total health.
She serves on Wellnesse's Dental Advisory Board, as a Clinical Advisor for Daily Dental Cares, and OrisDX, and as Vice President of Education & Development for North American Dental Group, where she leads evidence-based clinical education.
A Career Built on Root-Cause Thinking
Dr. Lee's interest in oral health started early. After an ATV accident as a teenager left her with extensive facial and dental trauma, she saw firsthand how the health of the mouth shapes overall health and quality of life. She went on to graduate second in her class from the University of Illinois Chicago College of Dentistry.
Her career has since spanned individual patient care, clinician development, and multi-practice clinical leadership. That range lets her speak to patients and dental teams alike, and she is a sought-after educator on the mouth-body connection for clinicians ready to look beyond symptom management.
