"My interest on airway health and its effects on the entire body has really brought all of my learning so far into focus. Being a dentist, I have extensive knowledge of the airway, and its intimate connection with the development of the orofacial structure, including the upper dental arch, jaw, and jaw alignment." - Dr. Henrichsen
