Words from our patients

A. P.: I was referred to Dr. Nazarian by my ENT in San Fernando valley after my ear drum failed to heal on its own. I didn’t know what to expect. He explained everything and was extremely compassionate to my situation.

M. F.: Genuinely, don’t know where I’d be today without your help. You’ve changed the way I hear and feel and will forever be so grateful. You and your staff were so kind to me throughout my experience and I couldn’t have asked for a better first surgery experience. You seriously changed my life! Thank you so much for everything.

A. D.: Thank you for all your help and support over the past two weeks and before. I genuinely feel that you really care and you want to keep on helping me going into the future. I have never met an ENT surgeon (especially in Ireland) that has been more caring.

S. P.: OHNI! I am so, so, so happy with my cochlear implants! I CAN HEAR AGAIN!!! Dr. Nazarian is the best! The first implant I did not know what to expect and was kind of scarred, but Dr. Nazarian made it so easy to adjust to my new hearing!!! Because I was so happy with the first one, I decided to go with the second one!
