A team focused on sleep apnea treatment innovation

Our interdisciplinary sleep disorders practice was one of the first of its kind. The Sleep Medicine Group, our primary clinical site is located in Portland Oregon.

Call or email to get the conversation started. While every diagnosis and treatment is itself unique, Dr. Joseph Zelk DNP, FNP, BC, CBSM, DBSM and his team has treated 1000s of patients over more than 15 years.​

We are the sleep clinic resource for all aspects of multi-specialty sleep apnea treatments. We have found, in our experience, that focusing on home sleep testing, dental appliance devices, Bongo RX (EPAP), and auto-adjusting CPAP therapy, along with hybridized treatments, we can achieve the most efficient manner to address the growing OSA population. The average wait for sleep consultation in the Greater Portland area can be months at other clinics. At Sleep Medicine Group a patient can often be seen within a week. We offer this same fast turn around time for our remote dental sleep medicine practices.

At our research division, Sleep Medicine Group, LLC, we have a team of sleep medicine team approache. With years of experience in the industry, we have the expertise to thoroughly innovate in the sleep disorders arena.
