My mom had him as a doctor in the hospital. He gave her her cancer diagnosis by calling it out from the hallway for all to hear, which is both against policy and just a horrific way to deliver this news to another human being. He also dismissed all our questions, made sexist jokes at very inappropriate times, and kept her hospitalized for much longer than we thought necessary.

Dr. Oo is like doctors used to be, before they seemingly all became only concerned with how much money they'll make. He really listens to his patients, and he takes his time with a diagnosis. One truly gets the feeling that he cares and is genuinely concerned; and he generates an atmosphere of trust. He has a great sense of humor, but can be serious as a heart attack when he is trying to get you to take your health more seriously. In this world of instant gratification where people are always in a big hurry, I am sure Dr. Oo will have people who will criticize him because you'll be there for awhile when you go to see him. He takes time with ALL his patients. He is intelligent, competent, and thorough. He is kind, and he is one-of-a-kind. To sum things up, I am quite frankly thankful to God I finally found him.

My uncle has been a patient of his for 20 years and he has had a 2 falls within a 2 week period and was admitted to the hospital both times. The second time being in the hospital he came in to his room told him "I told you would be back" "I am not talking to you" and walked out of the room. Is that how you treat your patients. I don't think that is very professional

I finally found a doctor who is competent , easy to talk to and has a wonderful sense of humor. He tends to run late occasionally but I believe it is because he ALWAYS takes his time to address each patient's concerns and to explain test results thoroughly in practical manner. I love him and have recommended him to several others.

Dr. Oo is extremely thorough, and I believe it is because of this that a patient may have to wait a few extra minutes. I hightly recommend.
