Dr. Shereen Lim, author of Breathe, Sleep, Thrive, is an Australia-based dentist with a post graduate diploma in dental sleep medicine from the University of Western Australia. She was one of Australia's first handful of dentists to obtain a qualification in dental sleep medicine. She has been involved in managing snoring and obstructive sleep apnea for over a decade and has seen the physical, developmental, mental, and emotional problems that are often associated with these breathing disturbances throughout the lifespan.

Her mission is to highlight root causes and promote airway health, or a shift from managing disease and symptoms towards ensuring healthy nasal breathing and good airway development from infancy. She works in private practice and has a special focus on unlocking greater health and wellness through addressing tongue ties, oral dysfunction (during infant feeding, swallowing, breathing, chewing, and speech), and guiding good jaw development during childhood.
