Our ENT physicians, Dr. Karen L. Stierman, Dr. Russell D. Briggs and Dr. Kevin Taheri, are experienced and dedicated to providing superior ear, nose, throat, allergy and sinus healthcare in and around Austin, Texas.

Our physicians have extensive training in all aspects of ENT care, treating both children and adults. Our up-to-date techniques include the treatment of complex nasal and sinus disease. We offer an array of new surgical technology for the treatment of chronic sinusitis such as balloon sinuplasty and computer-guided sinus surgery. We were the first ENT clinic in Austin to offer minimally invasive balloon sinuplasty and our physicians are leaders in this exciting new field in sinus surgery. Our ENT surgeons can now access three-dimensional CT scan images of a patient's sinuses during surgery. This is an interactive surgical device that allows identification of critical anatomic structures and treatment of diseased areas in patients with complex sinus disease.

The Ear, Nose, Throat and Allergy Center of Austin is also pleased to provide quality allergy care for our patients. We have a full-time dedicated allergy staff to provide allergy testing, allergy treatment, and allergy injections at our Austin (Westlake), Round Rock, and Cedar Park locations.

We have a special interest in treating childhood and pediatric otolaryngology illnesses. Ear infections, hearing loss, throat and tonsil infections are treated in a compassionate yet up-to-date fashion to ensure a positive outcome.

The center's professional staff also specializes in treating ear disease and hearing loss, dizziness and vertigo, facial nerve and Bell’s palsy, and balance disorders. We provide full diagnostic audiologic evaluations and offer comprehensive hearing aid consultations. We dispense all types of hearing aids from most leading hearing aid manufacturers.

Our physicians also offer treatment for head and neck tumors, including thyroid and parathyroid disease, throat and skin cancers, obstructive sleep apnea and snoring, and voice disorders.
