Dr. Yian came in alsmot rigth away and took his time to listen to the reason of my first time visit, and explained his treatment after a test done in the examing room. He made sure that he had answer ALL my questions before letting me go. He has a great bed manner and very caring about my health condition I will recomend Dr. Yian's practice to anynoe needing an ENT Dr. Last but not lease, the Staff was Excelent, totally a night and day different of what I read in Yelp.Thank you!!

This is an awesome ENT practice that puts patients first all the time. Beginning with the front desk, setting-up appointments and checking-in patients, and the doctors... everyone is patient, polite and very professional. My parents introduced me to OC ENT almost 25 years ago. Sadly both of my elderly parents have passed-away, but I continue to be a patient of the OC ENT. In fact, I drive 65 miles one way to be treated by the doctors at OC ENT.

It is VERY RARE that I go to a doctor's office and be seen on time. There is almost always a delay/wait for an average of 20-40 minutes of wait. However, I was able to see Dr. Son immediately without any delay. What a refreshing and stress-free visit! I feel respected as a person and my time was treated as equal in value to the doctor's. Thank you for running the office in a way that doctors' time and the patients' time are equally valued and respected.

May 10, 2022

Dr. John Sun is so nice and is patient when I have a list of questions for him. He kindly answers them all and is never in a rush. He preformed my sinus surgery last year, and I wanted him to check to see how I am healing. His office staff is very nice friendly each time I check in. I would refer Dr. JOHN Sun to anyone who is having any Ear, Nose or Throat problems.

Mar 15, 2022

I went to one doctor with bumps on my neck and he stated it both of you and leave them, then I went to see you all and you pretty much said the same thing but wanted to do an exam to see what they were. That seems a lot more professional! Definitely pleased with the entire staff!

Feb 4, 2022

I didn't realize I had been to your office several years before, but was pleasantly surprised when you told me I was already in your records. I was very pleased to see Dr. Sun (tough to see through the mask but I understand). I am encouraged by what he said about my right ear and hearing loss. I am looking forward to my hearing test and evaluation next Tuesday. Maybe this pressure that feels like water on the ear will go away and I will feel normal again. God bless you all and keep up the good work. And you can call me Ray. Ray Woolsey

Feb 3, 2022

I had an appointment for a hearing test. The Audiologist was super nice and efficient! She thoroughly explained the hearing test process and the outcome of the exam. The staff was very courteous and efficient. If you are in need of an ENT physician or a hearing exam, I would highly recommend the Orange County Ear, Nose & Throat practice!

Jan 14, 2022

Your office made it easy. Convenient appointment. Pleasant admin staff. The audiologist, Kristi, was excellent. I'll definitely be back in 12 months for a check up.

Jan 13, 2022

My appt. was on time and Dr. Shu was very nice and quick.

Jan 13, 2022

Dr. Yian is always courteous and gives the patient the necessary time and attention. He recently removed a long-standing ventilation tube and checked for a tonsilar stone. I queried whether the tube should be reinserted, thinking surely this was needed. Instead, he said, "let's see and give the ear a chance." Didn't push elective surgery! I love this type of nature/patient first perspective! Since I have tinnitus, we also did an audiology exam, which again, demonstrates his Audiologist is knowledgeable and gives time and attention to referred patients. Now going on 10 years with Dr Yian and still a five-star relationship!

Jan 13, 2022

Dr. Sun was great! took care of my issues quick and efficiently. He has a great bedside manor too!

Jan 7, 2022

Dec 7, 2021

Dr. Sun took the the time to explain my son's condition and answered every question I had. I did not feel rushed at all. The front office staff was professional and cordial. The facility was super clean.

Dec 2, 2021

Dr. Christopher Yian and his staff are always welcoming, efficient, and willing to assist me. Dr. Yian is excellent at what he does. He cares about his patients and when I have called his office asking a health related question I am surprised when I have Dr. Yian on the other end answering my concern. Considering he is a surgeon I know he makes every effort to get back to his patients as soon as he can and he certainly exceeds my expectations! I highly recommend Dr. Yian not only for his expertise but also his friendly demeanor. You will definitely be in good hands! More doctors should follow his lead.
