He takes time explaining diagnosis to his patients! I would recommend him 100%

Very thorough, impressively knowledgable, and kind. He read my charts and tests prior to the visit! It should be baseline but it is not! He even looked up a weird factoid I mentioned so he could correct a misaprehension I had about a proposed exam. He was willing to help me figure out what is going on, and that curiosity is what the medical profession is all about but sometimes rare to find. AND when I asked about potential healing he didn't cut off hope. He's kind and thoughtful. I really appreciated it. His staff are lovely and the office cheerfully decorated for the holiday. Only caveat would be a desire for a larger chair in the exam room but there were plenty in the waiting room. Stellar office and a great doctor.

Dr. Gao is very detail, very patient. He took time to read the record and go through many years ago’s history. Thank you.

My initial appointment with Dr. Kao was exceptionally positive. His commitment to understanding my situation was clear from his attentive approach. I particularly valued how he took his time to thoroughly address all my questions, offering comprehensive and easily understood explanations. I concluded the consultation feeling entirely reassured and confident in the advice I received.
