The day of the appointment, there was a power outage and the appointment was interrupted and the staff was very professional in getting us rescheduled right away and prompt on returning our phone calls and scheduling us for another appointment. I really do appreciate this office and staff. The only complaint I have is with the lab in the same building below. The girls that work there are very unprofessional, but that's the lab downstairs where they do blood work. Everything else was wonderful.
May 01, 2026
Yes, with this doctor, I really felt like he was listening to me and he showed that by asking if he could rotate my arm, which was bothering me in several ways, to determine more carefully where my problem was and I was impressed with that. Thank you.

Dr Wang is courteous, professional & always willing to help.
April 24, 2026
Very grateful Dr. Wang was able to see me right away. My Dr. (name removed) was not available, but I was given the option to see Dr. Wong. He listened to all my concerns and the pain I was experiencing. After reviewing results and examination of throat (had strep throat week before), I felt relieved as he explained the status of my condition. Dr. Wang sent my sample to quest lab. As soon as the results came in, he sent prescription to pharmacy which I was notified by the pharmacy plus his staff contacted me with the results. Highly recommend this doctor. Great experience! Thank you!
April 21, 2026
Dr Wang was very kind and compassionate. He listened to me and was very helpful to calm my nerves. I left the office much more positive than when I arrived. His suggestions will help me in the future to address my anxiety and insomnia issues.
April 20, 2026
Everything was wonderful. I had a good experience. I pressed the wrong button at the beginning because it's usually the other way around. Yes is one and bad would be four, but whatever. I'm fine. I'm happy. Thank you. Bye-bye.

Dr. William Wang is by far the best PCP I've ever had. I'm going to be 60 years old and I've just really used my PCPs to get referrals to the correct doctors. Dr. Wang is wonderful, thorough, friendly. He goes above and beyond with me all the time and he takes his time. I've never had so much help and kindness from a PCP. And (name removed) is wonderful as well. She's in the office and all the women up there are great.

March 13, 2026
Yes, Dr. Wang is an excellent physician. He's very specific. He runs the necessary tests that are needed and not, he doesn't run any unnecessary tests. He's very thoughtful and considerate. He explains in detail what the issues are and the next steps that I should be taking. So I would certainly recommend him to any family member that I have or any of my friends. Thank you for the opportunity to participate. Bye-bye.
March 03, 2026
Dr. Wang is very smart and helpful. He is kind and courteous.
March 02, 2026
Well, I was very well impressed because from all doctors that I have been seeing in PIH, this is the best. Wow, you know. I'm glad you have that as a doctor because he's kind. You know, try to help in everything, you know. I never saw a doctor like this. He's outstanding. You know, like I have another doctor and my family has a doctor in PIH, but you know. But he is what you want to see in a doctor that he cares and he tries to be helpful and kind. God bless him. Thank you for asking.

Overall, this is a good office. I've enjoyed my interactions with Dr. (name removed) and Dr. Wang. I think Dr. Wang needs to be more thorough and more patient. Dr. (name removed), I think, is fed up with me in regards to my illnesses and my symptoms. I think we rely too much on testing and the results. And when I say, hey, I'm still having symptoms, you know, for the most part, I think Dr. (name removed) and Dr. Wang, I think it's all my mind. Even though I'm still having symptoms and I try to get therapy and I try to do the best that I can, it's not their fault necessarily, but I think they need to be more detective and investigative in what they do as opposed to just ruling out things because certain test results. And I get it, that's how medicine works and how science works, but there are some times where a patient still, no matter what, the results say, you still feel symptoms.
February 25, 2026
It was good!
February 19, 2026
Dr. Wang made me feel very, very comfortable, especially when I asked him questions about my incontinence. So it was very personal, very hard thing for me to say subject, but his kindness. He was very, very kind. Thank you.
February 19, 2026
Dr wang was very thorough and sensitive to my needs. The entire staff was very friendly and helpful.

I had a great medical experience with the doctor. He listened to all my concerns, took great care of me, and I look forward to seeing him again in the near future. I really appreciate his caring that he provided for me and the awesome service that he did for me also. So yes, I would highly recommend him for family and friends. Thank you very much, Dr. Wang.

I was very pleased with my experience. Dr. Wang and the entire office staff were very friendly and professional.

A very good experience
November 04, 2025
It was my first time seeing this doctor. Everybody was courteous down to his nurse. And seeing the doctor for the first time, I really liked him and he listened to everything and explained everything to me. And that's what I really wanted in a doctor.
October 31, 2025
While it was sweet seeing office staff and physicians dressed up for Halloween, I would appreciate it more if provider wasn't wearing a full mask and sunglasses during my visit. Couldn't see facial expressions or see dr's eyes while we were talking - and this was my first appointment there, with that particular provider, to establish care. I was literally talking to a Dalmatian in sunglasses lol Maybe this helped break the ice with some patients; and maybe it was fun for existing/returning patients. But as a newbie, maybe at least take off the sunglasses?
October 28, 2025
Great Customer Service ... thank you so much
October 20, 2025
This appointment was made by the hospital for a follow up to my stay there. Dr Wang is not my PMD but I appreciated his information and recommendations going forward.
October 14, 2025
This was my first appointment with Dr. Wang. I came prepared with a printed document containing my more recent history, as well as my questions and concerns. He carefully went over the history and compared it to his notes from my previous primary care doctor. He addressed all of my concerns, and also went over all my medications with me, asking for background on each one (I have a lot of medications!) He diagnosed and suggested a treatment for a second degree burn scar on my back, and also set up a referral for a routine colonoscopy. He wants to see me again in three months. I feel like I'm in good hands.
September 24, 2025
I was most pleased with Dr Wang in how through he was and took enough time to under stand my concern.
September 17, 2025
It's always a pleasure to visit my providers office, staff and Dr. Wang!!
September 05, 2025
I think Dr. Wang is by far one of the best doctors I've had in a long, long, long time. And I'm 71 years old. So thank you. Thank you, Dr. Wang.
September 03, 2025
I'm sorry, now I understand why this guy had so many available openings. Basically, I was there, he gave me a lot of time, I explained and explained and explained, and all he kept doing was typing, typing, and then going, hitting the key to go backwards and erase it, and typing it again, and then saying, I really don't know why this happened to you. My arms and legs went numb, my hands were, they were like, closing shut. I couldn't even open them. I had to go to an ER. So this was my visit after the ER. And I left there feeling like I knew more about what happened to me than he did. I was so disappointed. It was a waste of my time.
September 02, 2025
I felt very welcoming. The office atmosphere was professional. The doctor was very thorough and I was very pleased when I left my appointment.

August 20, 2025
This was regarding Dr. Wang, William Wang. Late last year, I was going through a really tough time and I was seeking help. And I ended up finding that through Dr. William Wang, just his demeanor, the way he handled it. I was going through a tough time that I didn't know how to handle. And he put me at ease and told me that he had seen people, beat, you know, the situation that I was in and, and that gave me hope and, and it became true, but, I am so, thankful to, to Dr. William Wang for, for his, for his care.
August 19, 2025

Excellent customer experience. The nurse and the doctor were professional and attended to my request for an EKG. I was treated as a valued customer, which is very important to me. I definitely like this office and I would recommend it to everyone.
August 12, 2025
First time going to William Wang. Was a pleasant experience. He was very direct and listened to what I had to say. Would recommend him to my friends.
August 08, 2025
But he did not let me ask him a question that was not related to the sickness that I went for. I wanted to tell him something and he just was too busy with whatever was hurting me at the time.
August 05, 2025
Very polite and courteous. When my primary position retires, I would definitely continue with Dr. Wang.
July 23, 2025
