Great doctor. Always pleasant. Very knowledgeable. Five other doctors could not figure out my problem but Dr. JOAO DID!!
Always great appointment
Great Doc
Dr. Joao was very good today. He gave me two breathing test’s and medicine for chest congestion.
He’s doing a great job keeping this old boy healthy.
This was the most disgusting interaction I have ever had with a healthcare provider. I have spent months waiting on this appointment (for it to be rescheduled by the office saying I wasn’t allowed to see a different provider) and this appointment was because of a referral from another doctor. I had seen Dr. Jiao before months ago and he was lovely so I went into this appointment with nothing but the same expectations. I was laughed at by Dr. Jiao when I told him I was in this appointment because of something another doctor referred me for. He was condescending as well asking me what research I had done to come to the conclusion that I had and questioning the legitimacy of my symptoms. When I said I understood that there was not a definitive answer but what other explanation could he give for what I am experiencing, he again chuckled and said I “just have allergies”. I will be calling the practice manager.
His professional manner, his interest in my medical issues, he responds to any questions I have, his way of treating me are top notch. I recommend Dr Jiao!
He always takes his time to make sure that I'm doing well. You can tell that he really cares.
He was patient and listen to my problem and was very helpful in making suggestions as to blood test and other things that could be the problem.
His staff also work hard to go over and above in caring for patients. Thank you!
