"So kind, patient, enthusiastic, and very thorough."
Maxine is sleeping better and napping less during the day since starting treatment with an oral appliance instead of CPAP.

Loud snoring, gasping, waking up exhausted? Dr. Jeffrey Doneskey helps Seattle adults with snoring and obstructive sleep apnea breathe and sleep better with a custom, FDA-cleared oral appliance he designed himself.
Sleep apnea often goes undiagnosed. People blame their exhaustion on work, age or stress, while their partner lies awake listening to them snore and stop breathing.
Dr. Doneskey has more than 30 years of clinical experience, is a member of the American Academy of Dental Sleep Medicine, and invented the SilentPartner™ oral appliance. For many patients with snoring or mild to moderate obstructive sleep apnea, it's a quiet, comfortable alternative to the CPAP mask.
When you fall asleep, the muscles in your throat and mouth relax. In obstructive sleep apnea, your tongue and soft tissue fall back and block the airway. The SilentPartner™ gently holds your lower jaw forward, which keeps the airway open all night.
Every pause in breathing drops your oxygen and fragments your sleep. Over months and years, untreated sleep apnea is linked to serious health problems.

Answer the 8 questions of the STOP-BANG questionnaire, a screening tool widely used by sleep clinicians.
No overnight stay in a sleep lab. Dr. Doneskey's office offers home sleep testing with WatchPAT, a small wearable device that records your sleep time and sleep stages without an abdominal belt or nasal monitor.
We talk through your sleep, snoring and health, and examine your mouth, jaw and airway.
Take the WatchPAT home and wear it for one night. It tracks light, deep and REM sleep.
A sleep specialist interprets the study and confirms whether you have sleep apnea, how severe it is, or whether a full lab study is needed.
If an oral appliance is right for you, your SilentPartner™ is custom-made and adjusted until you're sleeping well.
Dr. Doneskey studied the connection between sleep problems and TMJ disorders, then invented his own oral sleep appliance. It gently moves your jaw forward to keep your airway open while you sleep, with a patented mechanism that makes fine-tuning simple.

Snoring and breathing pauses disrupt the sleep of everyone nearby. If your partner has noticed you snore loudly, stop breathing or gasp at night, that's worth a conversation, and worth an evaluation.

Dr. Doneskey has treated sleep apnea, snoring, TMJ disorders and facial pain for more than 30 years. He earned his DMD from the University of British Columbia in 1987, a Certificate in Oral Medicine from the University of Washington's two-year advanced program, and completed a two-year oral oncology fellowship at Fred Hutchinson Cancer Research Center.
Patients describe him as kind, patient, enthusiastic and very thorough. He takes time to listen, explains every option, and keeps adjusting your treatment until you're sleeping well.

Frank found Dr. Doneskey and the team professional and easy to work with, and prefers his SilentPartner appliance to CPAP.
Obstructive sleep apnea (OSA) is the most common form of sleep apnea. During sleep, the muscles of the throat and mouth relax and partially or fully block the airway, causing breathing pauses that can repeat many times a night.
Yes. For snoring and mild to moderate obstructive sleep apnea, a custom oral appliance like the FDA-cleared SilentPartner™ keeps your airway open by gently moving your jaw forward. It's quiet, portable and requires no mask. CPAP remains the standard for many patients with moderate to severe sleep apnea, and Dr. Doneskey will help you understand which is right for you.
The office offers at-home sleep testing with WatchPAT, a small wearable device that records your sleep time and sleep stages while you sleep in your own bed. A sleep specialist interprets the results, and the study shows whether a full lab study is needed.
Yes. The SilentPartner™ can also be used to reduce snoring even without sleep apnea, once an evaluation confirms it's appropriate for you.
Many insurers cover all or part of an oral appliance, though some don't. Check with your provider before your consultation, or ask the team to contact your insurer for you.
