English-Speaking Premium Sleep Clinic

Clionic Sleep Clinic is built on precision sleep medicine.
We prioritize patient comfort through a carefully designed testing environment, advanced diagnostic equipment, and evidence-based care aligned with American Academy of Sleep Medicine (AASM) guidelines.

 In Korea, it is rare to find a sleep clinic where evaluation, consultation, and treatment are fully available in English. For this reason, Clionic has become a trusted destination for international patients traveling from abroad, as well as expatriates living in Korea who require accurate sleep evaluation without language barriers.

Sleep disorders are rarely solved by machines alone. CPAP therapy, for example, often fails due to pressure intolerance, mask discomfort, or poor long-term adherence—issues only patients truly understand after real use. As an ENT specialist with extensive experience in sleep medicine, we focus on identifying the root cause of each patient’s difficulty and tailoring treatment accordingly, rather than applying one-size-fits-all solutions.

Accurate diagnosis creates comfortable, sustainable sleep.
