Our mission is to provide thorough, thoughtful, and compassionate treatment of conditions involving the ear, nose, and throat. We will determine why you are not feeling your best, will use state-of-the-art methods to get you better, and will empower you with the knowledge of how to prevent the problem from happening again.

As healthcare providers, our mission is to deliver the best care, employing latest treatment and surgical interventions. Specializing in conditions involving ear, nose and throat, we diagnose, treat and inform our patients about their health conditions.

We mainly deal with following conditions:

Examination of symptoms using latest technologies
Nearly 30 million Americans have impaired hearing. The most common cause of hearing loss in children is otitis media. For the elderly-the largest group affected-heredity is the most frequent contributing factor. >>Schedule An Appointment
Evaluation and surgical treatment of certain nasal conditions
Nasal congestion is very distracting and uncomfortable. Our treatment methods are designed to be as comfortable as possible and do not require nasal packing. Most of our advanced procedures are so minor, they can be performed right in our office. >>Schedule An Appointment
Resume your active and healthy lifestyle
Our physicians specialize in diagnosing and treating recurring sinusitis and facial pressure. When necessary, we use precise procedures, such as image-guided surgery, to maximize results and minimize discomfort. >>Schedule An Appointment
You may be experiencing obstructive sleep apnea (OSA)
Sleep apnea usually is a chronic (ongoing) condition that disrupts your sleep. When your breathing pauses or becomes shallow, you transition from deep sleep to a lighter stage of sleep which results in poor sleep quality>>Schedule An Appointment
Patients often develop tinnitus as a symptom of temporary hearing loss. Use of hearing aid for tinnitus may help relieve the conditions.
