Sarah Hornsby

Sarah Hornsby, BSDH, RDH, a dental hygienist who is practicing as a myofunctional therapist, will connect the audience to the role of the RDH in airway assessment and offer an in-depth look at the health consequences of mouth breathing and poor oral posture. She will explain the advantages of a transdisciplinary healthcare approach on refining collaboration and treatment outcomes.

In 2015, Sarah opened MyoMentor to train and support hygienists and dentists who want to incorporate myofunctional therapy into their practices and careers. In her current role, as the Co-Director of the Myofunctional Therapy Department at The Breathe Institute, she is actively involved in publishing research on myofunctional therapy.

Christine Nguyen

Christine Nguyen, OTD, OTR/L, an infant occupational therapist (OT), will delineate the role of an OT, including understanding sensory integration versus behavior, infant developmental issues that may arise from oral motor dysfunction, and why a thorough, whole-body evaluation is crucial to addressing infant tethered oral tissues.

She received her Doctor of Occupational Therapy from the University of Southern California in 2010. Dr. Nguyen currently works in private practice in Arcadia, CA, where she serves as the Director and Founder of One Child Specialized OT.

Brian Hockel

Brian Hockel, DDS, a general dentist, will share an overview of the clinical protocols to prevent or address airway issues in the pediatric population.

Dr. Hockel is a general dentist who limits his orthodontic treatments to therapeutic and/or protective care of the airway. After graduating in 1989 with a Doctor of Dental Surgery degree from University of California, San Francisco, Dr. Hockel practiced functional (retractive) orthodontics and various types of expansion.

Furthermore, she will explain the dental and craniofacial signs and symptoms in pediatric sleep-disordered breathing, evidence-based pediatric sleep screening, and which craniofacial phenotypes would be best treated through early intervention orthodontics for children under the age of five years.
