About Capital ENT
& Sinus Center
Capital ENT & Sinus Center is a comprehensive ear, nose, throat, sinus, allergy, sleep, pediatric, and hearing care practice serving patients across Austin, Lakeway, Marble Falls, and Dripping Springs.
Specialty ENT care with the convenience patients need.
Capital ENT & Sinus Center brings board-certified otolaryngology, audiology, allergy, and sleep care together in one practice. Patients come to us for common problems like ear infections, allergies, nasal congestion, and hearing loss, as well as more complex concerns such as chronic sinusitis, sleep apnea, voice problems, and pediatric ENT conditions.
Our goal is simple: help patients understand what is causing their symptoms, explain the options clearly, and offer care that fits their condition, anatomy, and goals. Many services are available in office, including diagnostic testing, audiology care, hearing aid fittings, CT imaging at select locations, allergy treatment, and minimally invasive procedures.

Four offices connected by one care team.
Patients can be seen in Austin, Lakeway, Marble Falls, and Dripping Springs. Provider availability and ancillary services vary by office, but each location is connected to the same Capital ENT team and care standards.
When additional testing, imaging, hearing care, allergy treatment, or a procedure is needed, our staff helps coordinate the next step so patients are not left piecing together care on their own.
View LocationsWhat Patients Can Expect
A specialist visit should leave you with more clarity, not more confusion.
A focused evaluation
Your provider reviews your symptoms, medical history, exam findings, and any testing needed to identify the most likely cause of the problem.
Clear treatment recommendations
We explain what is going on, what can be treated medically, what may need a procedure, and when watchful follow-up is appropriate.
Care that continues
ENT symptoms often overlap. Our physicians, PAs, audiologists, and clinical team coordinate care when more than one service is needed.
