I met with Dr. Alidad for a severe case of tinnitus. Was also referred to Emily, his audiologist, for a work up and found my hearing was not as good as it used to be (II’m 71) and hearing aids are in my future. Everything was explained to me, the tests conducted were necessary, and I’m very comfortable with the care I received and trust the folks from the kind staff to the wonderful doctors.

Dr. Cheng has been my ENT for a few years now. When I needed emergency surgery, he was on call and at the hospital in a matter of minutes. I think I was prepped and in surgery within the hour. He's always thorough and knows so many tricks that my previous ENT did not. He's also very personable. The office is usually pretty busy and the wait time can get a little long but he is worth it.

Dr Alidad Arabshahi is an awesome doctor and the best ENT doctor I have ever come across, his assistants and the staff are great too. I highly recommended this place for any one that is in need of an EAR NOSE THROAT doctor. Thank you all for your service.
I don't normally leave a review because people don't go way out for their clients but this one did that, Dr. Arabshahi. He's doing a great job restoring my 2yr old son's breathing. He could mostly breathe through his mouth & had a pause in his breathing at night which was so scary. He has had cold & been congested as far as a baby until his pediatrician referred us to this Dr. He's a great man, God bless him.
