    Dr Jacobs is the best allergist in the Bay Area, if not California. So experienced and amazingly…read morekind and thoughtful. Such an amazing diagnostician.

    Utter medical negligence by this so called team. I was anticipating a change in pharmacy benefits…read moreand a change in medication with the new year. I met with Dr. Jacobs on December 12 to go over the changes so we could get the ball rolling and not have a delay in my immune treatment which I require every 3 weeks to stay healthy due to a serious immune disorder. He assured me that it would be handled well. Then almost month later I call back and find out nothing has been done. The office didn't have a new script from the Dr. The contract worker they had hired to deal with insurance benefits at the office still didn't know I had a new pharmacy benefits provider. She was trying to order the old medication from the old benefits provider. So I spent the next two weeks on the phone for entire days - leaving messages, waiting on hold, coordinating between nursing staff (bc the dr was now on vacation), the independent contractor who didn't understand my insurance change, my pharmacy benefits provider and the pharmacy filing the order. Babysitting grown adults who are getting paid to apparently not do their jobs. The office at first admitted to dropping the ball, then they each slowly started to blame other people in the office and I realized what a toxic dysfunctional mess the whole operation was. Perhaps they once were good - the vast majority of these five star reviews are many years old. Today, I think they can handle routine allergy shots. That's their bread and butter. Anything more is a deep stretch for their abilities. In the end I finally got my medication two weeks late and it would have been even later if I hadn't borrowed a medical pump to use from a complete stranger. This was an incredibly stressful process that would have been avoided if people at this office understood how to do their jobs.

    Dr. Chang has been our family doctors for over 44 years since we moved to Bay Area…read more He takes care of everyone's health of my family. Now I am 82 years old, still actively doing exercise, studying new subjects, socializing with classmates and friends of every stage in my life. This review is our deepest respect to Dr. David Chang.

    Let me say, if this was just a review for Dr. Jue, I'd give five stars…read more He's a great doctor and for the two years I went here he was trustworthy and helpful. But it's the office. Every single time you make an appointment, they take it upon themselves to move it back. Not ONE time in the two years I went here did they ever honor the appointment time I made. So you make an appointment for 10:00 AM and you're driving in and get a text saying "don't forget about your 10:30 appointment." So every time you're sitting in the lobby for 45-60 minutes because these people think it's okay to change the appointment. Go to the office and look at how many pissed off people are sitting in the lobby. I make my appointments I put it on my calendar right away and put a post it on my monitor. Every time. The last time I made an appointment I did this and said if they move my appointment again, I'm done and sure enough they did. This is unethical in every way. People have lives and work and don't time to have their appointments moved around with out telling them. So every time I'd go in I was there for an hour and a half. This is NOT acceptable. Again, Dr. Jue, great. The people who run the office, the worst. I sucks because I had to go through a lot to find someone else, it's hard finding good doctors but the two doctors I've been to since both said this practice of moving the appointment time like this is not right. Keep that in mind if you go here.
