A Word From Our Founder

When I founded the Los Angeles ENT practice in 2014 it became immediately clear to me that the climate of healthcare in Los Angeles (and the country) was lacking significantly. Within months of starting my practice I realized that many underserved lives were being neglected.

It became my mission to change how healthcare is delivered in our community. Over time I quickly realized that there is a significant void within my specialty and that the typical office visit for patients is not consistent with the rest of the service industry. I wanted to create a place where people could feel comfortable that their problems would be solved no matter how big or how small. On a larger scale I wanted to change the way medicine is delivered in our community and our country as a whole. My mission is to change the public's view of medicine and change the medical community's view of how medicine should be delivered.
