dr greg reynolds


Dr Greg Reynolds - Somnodontist

Born in Christchurch, Dr Greg Reynolds BDS DipBus MScMed(Sleep Med) MMedSc graduated from the University of Otago Dental School in 1979, before embarking on several years' practice in Zimbabwe, South Africa and London. Returning to New Zealand in 1986, he operated dental practices in Christchurch and the West Coast.

Having developed a personal interest in sleep-disordered breathing (SDB), Dr. Reynolds's career in sleep medicine began at the Sleep Disorders Center in Shreveport, at Louisiana State University in 2000. Six years of full-time study and research later, he graduated with Masters degrees from both the University of Otago and the University of Sydney in 2006. His research theses on oral appliance treatment provided the foundation for his experience in the field of dental sleep medicine, Somnodontics™ and the ongoing development of dental splints for SDB.
His clinical practice is focused on non-surgical treatment of sleep/breathing disorders using special custom-made dental orthotics called mandibular advancement splints (MAS).  The MAS fits over the upper and lower teeth and is used when asleep.  It controls SDB by opening and stabilising a narrow, floppy airway, the basic cause of snoring and obstructive sleep apnoea (OSA).  The Somnosplint™ and SnoreMASter™ range of MAS appliances that Greg developed are suitable for many patients, particularly those with chronic snoring and less severe degrees of OSA.  The Somnosplint™ MAS may also be an effective alternative to poorly tolerated CPAP or invasive surgical procedures. 

Dr Reynolds was the first dentist to obtain post-graduate qualifications in 'sleep medicine' in Australasia and is the only one in New Zealand practising exclusively in this field.  For more information on dental appliance therapy for SDB or to make an appointment, go to


Dr. Naveen Pillarisetti - Paediatric Respiratory Physician

Dr Naveen Pillarisetti earned his medical degree in his native India but received higher training in the paediatric teaching hospitals of the UK. His fellowship in paediatric respiratory medicine from The Royal Children’s Hospital in Melbourne meant he was close enough to set his sights on New Zealand. When he was offered a position as a paediatric consultant at Starship Hospital, it was the perfect excuse to stay in a part of the world he loves.

Naveen recently conducted research into early cystic fibrosis lung disease and is currently looking at the role of airway microbiome in bronchiectasis. He hosts several paediatric respiratory out-reach clinics around the country and teaches at both a student and post-graduate level.

Working with children has its own set of special challenges but, Naveen believes, early intervention in disorders of a respiratory and sleep nature can have significant positive impact on the health of a patient as an adult. He is married to a developmental paediatrician and the couple has a teenage son and active Labrador to keep them occupied on the weekends.
