    Dr Xu has been my allergy and asthma doctor for many years. I developed severe allergies and asthma…read morein adulthood. Year after year, I suffered so much from allergies and never expected to find the relief I'm now experiencing. Dr Xu is my favorite doctor (I have several) and has helped me get my symptoms under control. Her care has been positively life changing. I have complete confidence in her expertise. She is a highly skilled and sought after expert in the Bay Area. Her practice has a few locations in the South Bay which makes scheduling very convenient. Her staff is well trained, friendly and helpful. Dr Xu is thorough, takes time with each of her patients, she's kind, compassionate and very professional. She has excellent communication skills and explains things in an understandable manner. I never feel rushed and always feel like she truly cares about me and my overall health. I highly recommend Dr Xu and the team at South Bay Allergy and Asthma Group. Five Stars all around!

    I'm so disappointed in Dr Xu and all her practices…read more First of all, she added herself onto my care team without prior consent or as much as to even ask me or speak to me. I just received an email saying that she's been added to my care team even though she's not in network. Secondly, to charge my insurance $3,000 for allergy testing is completely insane, I understand prices have gone up but to blatantly price gouge , shame on you. These people only care about one thing and that's money! Dr Xu was not personable, was snappy when I called about lab work she ordered for tests that don't even exist (how are you an allergist and you don't know that these tests you've ordered don't even exist, like there is no lab that provides these tests at all). And on top of that provided my primary care doctor a rude note of my visit with her. I did not consent to this either it just happened.

    Lena has been a godsend for me. Over the years she has helped me probably more than any other…read moredoctor I have. She regulated my thyroid when nobody else seems to figure out the dose I needed to be on and helped me with all my vitamins. I have ADD and she has helped me combine the medications I am on with the correct vitamins needed to keep me healthy. Recently she added a large dose of B12 to my regiment. I had really bad RLS (restless leg syndrome). Had it as long as I can remember but had gotten worse over the last couple of years. She thought I might have a B12 deficiency. Guess what? I did! Within a couple of weeks the RLS was gone. I was shocked. Although I shouldn't be considering what she's done for me in the past. She's constantly reading up on new breakthroughs and is up to date on everything. She has figured out all my issues because she has run tests that no other doctor recommended. They were all helpful. She's the nicest person you will ever meet and her care and understanding of my particular issues was amazing. She listens and takes the time to figure out exactly what's going on and sometimes a simple vitamin can cure years of pain and discomfort. In a nutshell, she's the best.

    I had an extremely frustrating experience with South Bay Allergy & Asthma Group. I scheduled what I…read morebelieved would be a straightforward appointment and was never informed about the cost of the visit or any additional testing beforehand. Weeks later, I received a bill for 1,400 for a simple allergy panel. (they billed my insurance $2500) The most frustrating part is that there was absolutely no transparency. If patients are going to be charged hundreds or thousands dollars for testing, consultations, or separate services, that should be explained clearly before anything is done -- not after the fact when the bill shows up unexpectedly. When I reached out about the charges, I felt like I got very little empathy or accountability; Even at one point being told I didn't know how to read bills. Medical offices should understand that people budget for healthcare and deserve to know what they're agreeing to financially before being treated. The billing process completely ruined the experience for me. I would strongly encourage anyone go to a more forthright office. I NEVER WANTED FREE SERVICE, I WANTED HONEST SERVICE, unfortunately I didn't receive that here. I have also submitted a few complaints to the medical board. I've attached my bill to this review.

However, when I tried to schedule a simple Telehealth follow-up to review my results, I was told I'd need to pay $240 cash upfront and then wait for insurance reimbursement. When I pushed back pointing out they're in-network with my insurance plan and asking why they couldn't bill insurance directly, the story changed. First I was told "health plans no longer cover Telehealth visits starting January 1, 2026". I called my insurance company directly, and they confirmed my plan covers Telehealth with no deductible. When I shared this with the office, the explanations for why I couldn't have a simple video call to review results I already received. I ended up canceling altogether. The medical care was fine, but the billing runaround and inconsistent answers made me lose trust in the office. I'd recommend clarifying their Telehealth and billing policies upfront before committing to any treatment plan here.
