I was very pleased with my experience. Dr. Wang and the entire office staff were very friendly and professional. Dr. Wang was very thorough in his research of my medical history and gave me excellent advice. He diagnosed my condition and prescribed medication which has cured most of my symptoms in only one day. I am very grateful to be a patient of Dr.Wang.

He's is very happy that he's been replaced with our retired doctor, Dr. (name removed). And I've been going to him for a year. He's an excellent doctor. I'm very much satisfied. He's very caring and just really takes time to find out how things really are with you. Yes, I'm thankful for him. Now can I give a 10 for him?
January 16, 2026
Dr. Wang and his staff are wonderful. From the moment I checked in, I felt cared for. The nurse was welcoming, and the doctor listened to me and answered my questions. I trust him with my medical care and am happy he is my doctor.

Dr Wang was very knowledgeable regarding the field of internal medicine. Dr Wang was thorough and focused in his examination and recommendations for my annual wellness visit and medical history. Medical assistant Christina was very professional and friendly and explained everything I needed to know during my visit.

Dr. Wang was extremely thorough, listened patiently, and took all the time that he needed with me. I did not feel rushed. I felt like he was focused and interested in what I was saying.

I love that William Wang's office is very thorough with my blood pressure and goes over all my information with me. And Dr. Wang is very helpful with giving insight on managing my blood pressure and weight control. And his assistant, (name removed), is awesome. She always makes the visit enjoyable.
December 12, 2025
Dr. Wang is extremely patient and listens very deeply so the patient feels heard, which is very healing in and of itself. Very open to hearing another opinion or question or wondering and highly recommend him. He's super amazing.

The therapy I was told I could receive with my insurance did not accept my insurance.
November 13, 2025
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.
September 02, 2025
Nurse (name removed) was very helpful.
August 29, 2025
Very through . I really liked him, easy to talk to and explain everything completely.
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
I hope I continue to see Dr william wang for future visits I was really satisfied with his care thank you and have a nice day
August 18, 2025
Dr. Wang is excellent, thorough, thoughtful and very knowledgeable. He is an excellent replacement since the passing of Dr. (name removed), my former GP. Thank you Dr. Wang!
August 13, 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
I was attended right away. The staff are helpful and kind. The doctor diagnosed was easy to understand.
July 22, 2025
For being the first time I consult Dr. Wang...very professional...he listened to my problems and was patient in explaining my questions and if I have to make another appointment I would do it with Dr. Wang. Thank you.

Dr Wang was very thorough and explained as he examined me of what he saw or thought based on my symptoms which reassured me that he would find a way to help me recover. Thank you Dr Wang.
July 01, 2025
I am impressed with Doctor Wang. I would consider changing my primary care provider to Doctor Wang should my current PCG no longer be available.
June 26, 2025
The reason why I came to see this Dr. was an medication question but they went ahead and gave me a whole exam and the answer that I was looking for plus a referral to a specialist, very helpful thank you all
June 23, 2025
Excellent doctor
June 11, 2025
It is too early for me to fairly evaluate this physician.
June 06, 2025
Just note the last question, I pressed one by mistake. But yes, I would recommend to a family member. He's a great doctor.
June 04, 2025
SUPER GOOD.
June 04, 2025
I never liked to have doctors visits before, but now with Dr .William Wang I will look forward my appointments, very nice indeed.
May 28, 2025
This young physician was intensely thorough in his examination, but short on minor details such as eye contact, knocking before entering the room, and introducing himself.
May 23, 2025
Excellent!!! Dr. Wang was very helpful and explained everything clearly.
May 22, 2025
Dr. Wang knew just what to do to help me with a volunteer work clearance form. He evaluated my vaccination history and requested the lab tests I needed. He is a great listener and communicator!
May 20, 2025
My experience with the doctor was great really enjoy it. He made me feel comfortable answering my questions. Well definitely see him again if possible great doctor in LA.
May 15, 2025
They got my dad in within two hours of making an appointment. He had leg pain, but unfortunately last night his pain got so severe he couldn't even walk so I still don't know what's going on with him. Might have to take him to emergency.
May 13, 2025
I'm very, very satisfied with this service. The staff there is very polite and good. And Dr. Wang, oh, I just love him. He is so thorough and so easy to talk to that I would recommend him and the service there for anyone. It is very, I'm very satisfied. And Dr. Wang, thank you so much. I really appreciate you as a doctor. Thank you, Dr. Wang.
May 05, 2025
I called to try to schedule an appointment with Dr. (name removed). He wasn't available, but I was able to get in to see Dr. William Wang. It was the first time I'd seen him. I think he's a fine doctor, but I would need more experience with him. I don't (INAUDIBLE).
April 25, 2025
It was a pleasant experience
April 24, 2025
I'm very happy with the service he gives. He explains everything to you very well, and I'm happy with him. Thank you.
April 18, 2025
Yes, I appreciated this provider's thoroughness and he was very serious and very thoughtful. The only problem I had, it was a little difficult hearing him under the combination of mask and the helmet, plastic helmet. And I had a little trouble and I am a little hard of hearing and that was my only concern. I had to ask him to repeat things several times. But I'm very, very grateful for having seen this provider. Thank you. Bye.
April 17, 2025
First time with this doctor. He gave me his time for a through exam for surgery. I feel confident and ready! Thank you
April 16, 2025
Dr. Wang and the staff are a great team. Same as the X-ray department very professional and caring person
April 15, 2025
I truly enjoyed the doctor. That's the first time I've been there. So I was kind of scared, but I was okay, and he made me feel comfortable. So I really liked him. And I'm going to be seeing him next month, so I'm going to be looking forward to that. Okay. Thank you.
April 15, 2025
It was much better than what I had before, more though. My previous primary care physician never touched me-never checked my eyes, ears, heartbeat, etc. the office staff at the previous primary care physician were also fairly rude. I'm very happy with the change and hope I feel the same about the ophthalmologist referral.
April 10, 2025
I had thorough checkup, was impressed and glad I went to this health provider
April 09, 2025
Do not like this DR next time i will wait for my DR
April 04, 2025
Dr. Wang was an excellent doctor. Never met him before in my life. He took time to hear me out and everything. He even followed up on something that I needed that he made the call personally to me to make sure I was taking enough protein. I appreciate that. He's going to be my primary doctor from now on. I trust him and I will recommend him to anybody that asks of me. Thank you.
April 02, 2025
Dr. Wang was very professional and compassionate to my concerns. A pleasure to have seen him.
April 01, 2025
Dr. Wang made me feel heard. When I shared a medical issue with him he stopped typing on the computer and faced me. He gave me his entire attention and I felt that he treated me with respect.
March 25, 2025
I used to have Dr. (name removed) as my physician and because of convenience reasons I stopped coming to her, but I returned and so I was set up for as a new patient, which is understood. But when I was setting up my appointment, whoever answered the phone, I don't know if they understand or if it could be communicated to the patient better, but they weren't clear about the process. And so I originally set up my appointment with Dr. (name removed) for April 28th, but then I asked, I was trying to get in sooner. And so the person on the phone said I could see another doctor as a new patient and then I can come back to Dr. (name removed), but I have to have a new patient consultation or session first before I start being seen as a regular client. So when I came in...
March 21, 2025
Yes, the doctor provided very quick but thorough testing, tested me thoroughly and made sure I was okay. And I was very happy with the appointment. He was able to identify and rule out any other symptoms. And I appreciated that very much. And he was very customer service oriented, very friendly. I appreciate that very much. Thank you.
March 21, 2025
This is the first time I have seen Dr. Wang. Dr. (name removed) is my doctor and she is on vacation.
March 19, 2025
I really liked the doctor I saw. The only main problem I had was when I called to make an appointment, it was my first time visiting the receptionist that I couldn't see any doctor until the middle of August. And I said that was not reasonable and I needed to speak to a manager. Later a manager called a few days later and she allowed me to come in last week, which was much better.
March 17, 2025
Thank you for your time and care Dr. Wang.
March 11, 2025
Dr. Wang is a calm, pleasant and caring individual. He spent time with me and try to make certain I did not forget any of my issues.
March 11, 2025
Very good doctor! Dr. Wang throughly examined me and asked many questions. I felt really at ease and in good care with his excellent knowledge and advice. He was very good!!! Thank you!
March 05, 2025
Not only was the doctor professional and courteous. You spent more time with me than most doctors do. And he's seeking other medication that would be more beneficial to my needs as a diabetic and asked questions pertinent to my needs. I have a good feeling and feel relaxed with Dr Wang and staff who are very curious.
March 04, 2025
I'm very satisfied with the Doctor and Nurse who interpreted for me.
February 27, 2025
Even though I was not able to see my PCP, they were able to accommodate me with another doctor (Dr. Wang) for a next day visit. He did a great job and was thorough
February 26, 2025
He came prepared, meaning he read my file before seeing me. Efficient. Pleasant manner.
February 26, 2025
First time to see Dr. Wang. I had no problem with him. Dr Wang was very understanding and polite. He spent enough time to explain everything. The problem was I had to see if they forgot about me, cause other people were called in before me.
February 20, 2025
Okay, you got me in real quick, took care of me, listened to me, and took care of my problem like almost immediately. I appreciate it very much. Thank you. Bye.
February 18, 2025
Dr. William Wang is an excellent primary physician. Would recommend to all of my family and friends.
