Pre-Conception Airway Care Education (PACE) Act
Date: 2025
Role: Primary Author and Policy Lead
Established a federally endorsed, state-wide preventative health policy initiative focused on educating women of reproductive age about airway health, sleep disorders affecting breathing, and strategies to reduce maternal and neonatal complications.
Note: This complements initiatives like the WELLS Act to prevent adverse maternal and neonatal events.
Presented to and accepted by federal health policy channels.
Newborn Early Childhood Tethered-Tissue and Airway Resistance (NECTTAR) Act
Date: 2025
Role: Primary Author and Policy Lead
Established a forward-thinking federal public health policy initiative designed to optimize airway and craniofacial health from birth through adulthood. Supported by public health officials, it empowers clinicians to identify and address airway and respiratory issues before they develop into chronic conditions.
Presented to and accepted by federal health policy channels.
