Sleep Apnea & TMJ Specialist Serving Newcastle, WA

Newcastle is a hillside residential enclave between Bellevue and Renton with sweeping views of Lake Washington, the Seattle skyline, and the Cascade Range. For residents here dealing with disrupted sleep, chronic jaw pain, persistent snoring, or CPAP frustration, Dr. Jeffrey W. Doneskey provides focused diagnostic and treatment expertise from his Bellevue office — just 10 minutes from Newcastle.

Dr. Doneskey is a certified Oral Medicine specialist, not a general dentist. He completed a two-year advanced education program at the University of Washington School of Dentistry specializing in TMJ disorders and oral medicine, followed by a fellowship in Oral Oncology at the Fred Hutchinson Cancer Research Center. With over 30 years of clinical practice, he invented and patented the SilentPartner™ — an FDA-cleared oral sleep appliance that treats obstructive sleep apnea while protecting jaw joint health.

Why Newcastle Residents Need a Sleep & TMJ Specialist

Newcastle’s hilltop geography and forested lots create a quieter sleeping environment than urban areas — which paradoxically means snoring and apnea events go unnoticed longer because there is less ambient noise to mask them

Newcastle’s proximity to Bellevue means residents here work in high-pressure Eastside corporate environments where stress-driven bruxism is prevalent but specialist TMJ care is surprisingly scarce

Named after the coal mining operations that fueled early Seattle, Newcastle today is one of the Eastside’s most desirable residential communities — and one of the closest to our Bellevue office
