Everything was fine. I would just typically wait until after more than one visit before "Highly Recommending" anyone.

Dr. Oh is really caring patients
May 14, 2025Seok won J.Verified patient
I appreciated the kindness and expertise of the staff - and Dr. Oh! He was great. I suggest to the staff that if a new patient has an appointment following lunch that they inform said patient the office will be closed and locked up. I arrived early to find the office and to fill out any additional forms and had to sit for 25 minutes before they returned from lunch.

Dr Oh, his PA and the entire staff were friendly, helpful and knowledgeable. His PA spent quite a bit of time with me going over symptoms and concerns before she brought Dr Oh in to see me. He was smart, kind and patient. He provided me with information and options for treatments, medications and supplements to treat me. I felt like they listened to me with patience and genuinely cared about my well being.
November 2, 2022Ashley D.Verified patient
Staffs are friendly. I didn't have to wait long before the doctor saw me. Dr Oh is well mannered and I he responded well to my questions and concerns.
October 18, 2022Judy G.Verified patient
Dr. Oh was really nice. Took the time to listen to what was going on, did his usual examinations, and then explained what the next options are. I really appreciate that it felt like he really was listening, and asking more questions to figure out what might be going on. He also was great at explaining what he saw and what his thoughts are. I appreciate that when he started, things went pretty quickly, but I did not feel rushed at all. Office staff was friendly too, and overall was an easy process. Would highly recommend.
February 7, 2022Jessica L.Verified patient

Dr. Oh is very caring, and takes his time when examining you. I had 3 other doctors look at my ears before seeing him and he was the only one who was able to help me. I really appreciate him.

February 24, 2020Shulong L.Verified patient
My time with Dr. Oh was great and through and he answered all my questions. The receptionists seemed too busy to interact much with me and didn’t seem like they had much time to help me with my concerns. That would be my only issue with this experience!

Dr. Charles Oh is an excellent ENT. I am so thankful for him & for the instant relief after he conducted his procedure to remove my earwax.
I highly recommend him! He is very knowledgeable, patient, caring & easy to talk to about your concerns & needs.
Myralynn B.Verified patient
Doctor Charles Oh was compassionate and attentive to details of my problem. He was able to find symptoms that other doctors failed to diagnose. That resulted to suggesting alternative but a very reasonable and promising treatment.
Highly recommended.

I was seen immediately, Dr. Oh very kindly listened to everything I had to say, and forwarded recommendations for me to get a scan at another office within a couple of days. Highly recommend.
February 8, 2017Sophia N.Verified patient
The doctor is very professional. I really like that he wanted to hear what really happened first before jumping to the conclusion and just checking. He is very polite and smiling at all time.
October 5, 2016Radee P.Verified patient
I was recommended by a friend to see Dr. Oh. His staff was super friendly and he was very attentive. He really listened to what I had to say and even gave me a couple options for treatment based on what my insurance had to offer. Overall, it was an awesome visit. I would highly recommend him to anyone looking for an ENT doctor.

September 12, 2016Edward G.Verified patient
Dr. Oh was incredibly kind and knowledgeable, and addressed all my questions and concerns. All of the staff are friendly, and the office has a very pleasant atmopshere. There was hardly any wait time to speak of. My experience was excellent, I'd highly recommended Dr. Oh!

The office staff was very friendly. The staff who took me to the patient room seemed genuinely interested in why I was there and what I did for a living. When I paid, she asked if I received the good news I had been hoping for and also told the other office girl my exciting plans for the summer. Extremely friendly and pleasant to be around.
Dr. Oh took his time to understand my situation, past and present. He gave me advice on what to change or how to make things better. He gave me the option of watching the TV as he scoped my vocal chords -- which was a really cool experience to see first-hand versus looking at a diagram. He asked if I had any questions, answered each question without making me feel stupid and took time to explain things I didn't understand. He never seemed rushed or gave the impression he didn't have time for me. Incredible Doctor!
March 29, 2016Samuel F.Verified patient
I was very pleased with Dr. Oh. He had a great demeanor and spoke clear English as well as explained everything clearly and understandably.
March 5, 2016Helen L.Verified patient
Very mediocre doctor's visit. Didn't gain any real helpful insight that I didn't already know via the world wide web. Came in hoping to fix a snoring issue and basically was told I should try a nasal spray, adjust my sleeping position, a sleep test, etc. I've basically already tried all of those suggestions thanks to some common sense and the internet so I'm back right where I started. 15-minute consultation took a nice hit to the wallet.
January 14, 2016Norby R.Verified patient
So refreshing to make an appointment and be seen on time! There was no wait! I didn't even have a chance to sit in the reception room.
Everyone was kind and professional. Dr. Oh was not rushed and took the time to listen and address my concerns. Thank you!
