Dr Ou is my fave doctor actually and ive moved around some and have gone thru quite a few doctors…read more He and his wife are so nice and smart! As a PCP, Dr Ou asks all the right questions and does commonsense treatment plans or sends you to further exams for any mystery pains. Staff is almost abrupt but friendly enough. lately, ive been asking for a referral and its been taking over a week. Now, in fairness, we did this over the phone and she was trying to prevent me from coming in physically just to ask for a routine physical test...but maybe they still needed me to follow up? it would be nice if i didnt have to. as far as i know, doc takes in both PPO and HMO and a variety of providers. i also love that i can communicate with him through his health portal (theres an app) and it also displays the results of your exams sometimes and summaries of your visit. I've made appointments using the app and asked him pertinent questions which he answered - unlike some docs who would probably be like, "oh i dont know, come down for an appt so i can check" Dr. Ou is very knowledgeble but he will never be annoyed when you offer information /treatment possibilities about a previous or recurring illness. He is COOL! Parking in front is limited but i've never had a problem getting a spot.

Not a pleasant experience at all. I've had this doctor listed as my primary care physician on my…read moreinsurance card for over two years. I called the office today to schedule my annual physical check-up, and the doctor himself answered the phone. He ran my insurance information through the system, and after verifying all the necessary details, he informed me that he is no longer accepting new patients. This is beyond ridiculous, and I wish I could leave a zero-star review for this unprofessional practice.

Dr Wu is a good dr! He spent enough time with his patient and is willing to listen. I also referred…read moresome of my closed friends to him. , but for some reason they don't want to go back. I've seen him many years at his other clinic. More than 1 year ago. I changed my insurance co so l need to go to his main clinic. I saw his front desk girl named Jennifer was kinda rude and impatient on the phone talked to the patient when my first day walked into the office. So I was very careful talking to her. Last month, after seeing dr Wu, I forgot to ask him to apply an ab ultrasound, so l called the office and spoke with Jennifer on the next day. She said I need to make another appointment to see dr Wu in order to get the ultrasound. But it takes long time to see dr Wu so she said I can do phone appointment. I know they don't want to do it for free, so I made a phone appointment a week later. After the phone appointment. I explained my situation with dr Wu, he gave me an ab ultrasound so I went 2 weeks ago. When I went to the place, the nurse told me the ultrasound I have is only for the lower ab. she suggested to ask dr to write another latter for me to do upper and too. So I called the office and talked to Jennifer and told her what nurse said. Jennifer told me I need to make another appointment again! I was very frustrated and asked her please ask dr since I am one of his old patients. She said: I am not his old patient at this office! She was very cold and no mercy and not kind at all! I decided to switch my family dr to another has very good reputation next day. When I went last week, they had a full house patient in the lobby, but the front desk lady and all other employees were all very friendly and patient. I was really impressed and glad my decision to switch the dr. I feel sorry for dr Wu didn't train his front desk person to be friendly, nice and professional. I guess lot dr they are busy, they might know how to take care of their patients, but forgot their employees specifically the front desk need to take extra care to the patient too since they work as a whole team.

Great Dr, Doctor Wu has been my PCP since 2016. Very knowledgeable Doctor and staff with a caring…read moreheart. He was extremely helpful and easy to talk to, a great listener and straight forward and helpful with talking through all the options. Dr Wu was attentive and truly cared for his patients.

Since I have returned, they have actually tried to explain their actions on the phone and that…read morethere was no intent to cause alarm. I have asked that they change their tone on phone calls to be more reflecting of any news. I hope that they are doing this with all patients leaving terrible reviews as they really can't handle any more negative ones. For my follow up, I saw Dr. Wang, who is my supposed to be my primary but I know she is incredibly busy. She is an amazing doctor and physician. She genuinely cares about her patients and their well being. Her time with me was incredibly limited but still managed to add in a yearly test that I have never done and ask about a cold I was fighting. She explained the procedure to me since it was my first time. She referred me to doctors for my follow up. She took the time for patient care. This is 180 degrees different from the male doctor that I first saw. I am absolutely grateful to Dr. Wang for taking the time to give me a check up as I have had no time or insurance to get these necessary checks until now. She is a wonderful doctor, no wonder it is so difficult to get an appointment with her. I have received additional phone calls from the office, thank you for changing your tone on the phone. It made me much more comfortable while listening to what you had to report. As promised, I would be revising my review but most definitely not taking it down.

This was my first visit to this facility to see a doctor, and the doctor was excellent. However,…read morethe reception check-in process is confusing, and the three-month scheduling window makes annual exams unnecessarily difficult to arrange--especially for older patients who must remember to call at exactly the right time. I was able to schedule my annual exam in advance at another office, and this facility should offer patients the same convenience and consideration.

Pediatrics - I started going to St. Jude when we went to Dr. Mathur for our first born a few years…read moreago as she had great reviews online. We have no complaints with her other than she does get busy and the schedule fills up quickly. There were times we had to see the other pediatrician, Dr. Alejo, instead due to scheduling. We found Dr. Alejo to be soooo personable and always went out of his way to ensure we were informed and cared for. Because of this, we switched over to Dr. Alejo as the PCP and are so happy with the service he provides. OBGYN - Dr. Du and Verina (NP) were the two I most often saw during my pregnancy. Both extremely friendly, personable and will take the time to answers questions, otherwise, office visits are standard and quick. Great experiences overall with both! Office has gone through extensive renovations and is very modern, clean and spacious. There is even a little seating area for the kids with a tv to keep them occupied / entertained while waiting. Located in the same plaza as The Habit / Sprouts / Ross. Shared parking lot with ample amount of spaces, never an issue.

Finding a PCP who truly…read morelistens can be difficult, but Dr. Hajal took the time to address all of my concerns and thoroughly explain my lab results and treatment plan in a way that was easy to understand. The office is clean, organized, and the staff are friendly and easy to communicate with. Scheduling and follow-up have been smooth, and I never felt rushed during my visit. I'm very happy I chose Dr. Hajal as my primary care physician and would highly recommend him to anyone looking for a knowledgeable, caring, and thorough PCP.

About a month ago I received an email from this office saying I needed to get a new medical card…read moreshowing Doctor Hajal needed to be listed as my primary doctor on my medical card. First of all, I never saw Dr Hajal. I saw Dr Khaleel and was very happy with my visit to her last year. I call the office and the one time I got someone on the line who said yes, our office needs to be listed on your card for you to continue to come here. I call anthem and they dispute that saying I can go to any providers and there's no reason to issue me a new medical card. Since then I have called La Vista multiple times and received no answer. I have left two messages, and gotten no call back. I emailed on the app, No response so I booked an appointment on the app only for it to be canceled today without a reason why. Maybe if someone from their office staff answered the phone, I'd have an answer. Fuck this place and thank you for making me go through the whole process of looking for a doctor again.
