I found Dr. June Zhang through the positive reviews on Yelp. I'm so glad I did because every…read morepositive review about her is true! She's extremely nice and bubbly. She's very intelligent and was very thorough in her approach for my severe, full body eczema. She put me at ease despite how crappy I felt at the time. She took the time to listen to my concerns and addressed them all. I have experienced many doctors who sent me home with steroid creams and ointments without any concern for the outcome or my quality of life. She even called me after my visit to follow up on topics that she found more information on. Dr. Zhang changed up my medication therapy and has introduced me to many lifestyle changes so I can better control my skin without relying heavily on topical steroids. She has changed my life for the better and I would not go to any other allergist.

While I found the treatment effective during the first year and appreciated Dr. Zhang's nice…read moredemeanor, I experienced several ongoing concerns with the overall office operations. My main issue is that this office has always felt like a money-grab. The office often recommended additional tests and appointments that did not seem necessary. Although I understand the value of Ni-Ox and lung function assessments, the repeated testing rarely resulted in meaningful adjustments to my treatment plan. Appointments frequently ended with vague feedback rather than clear next steps for improvement. During one visit, I had a reaction to the shots, which was a stressful situation. The staff appeared uncertain about how to respond, and Dr. Zhang invited a medical assistant to observe my hives without asking for my consent. This was uncomfortable and dehumanizing. Additionally, I received the bill for this appointment and they charged me for a lung function test I did not take. I contacted the billing department who said they would call me back. I never received a call back despite following up. I check today to see they have revised their billing statement to deduct that charge. Very shady business that prioritizes money over patient care. I am now seeing a new allergist who looked at my tests and said that allergists should not be administering shots to people with numbers as bad as mine were.

Finally Free From Allergy Meds After 30 Years -- Exceptional Care at SH Medical Allergy…read more At 60 years old, I've seen a lot of medical practices over the years, including some of the best, such as Stanford and the Cleveland Clinic. SH Medical Allergy is truly one of the best medical practices I've ever experienced. I actually chose this practice over UCSF, where I often receive care, because SH Medical offers accelerated allergy shots so patients can reach the benefits faster. For me, that approach has worked remarkably well. I had been taking allergy medications intensely since about 1995, including antihistamines and nasal steroids. Now, for the first time in decades, I'm able to get by without either--and I'm no longer dealing with sinus infections. It honestly feels like a huge liberation. Dr. Gupta is exceptionally warm and attentive to detail. She helped me recognize that I likely had an underlying sinus issue and referred me to a specialist, which I greatly appreciated. She was also incredibly compassionate and accommodating when she learned about the sudden death of my partner of 16 years. Her office staff is outstanding. During a penicillin challenge, two of her newer medical assistants, Rishabh Agarwal and Shivaang Vyas, were incredibly comforting and kept me company throughout the process. They patiently answered all of my questions, were very gentle when administering the shots, and even explained how they count breaths--something I was curious about for my own research and teaching. The Castro office itself is delightful. The staff decorate for every holiday, which makes the office feel warm and welcoming. It honestly makes me feel like I'm back in elementary school in the best possible way. Jessica and Rachel deserve special mention as well--they do a wonderful job decorating and also act as warm hosts of the office. The entire environment feels thoughtful, friendly, and genuinely caring. I would recommend SH Medical Allergy without hesitation to anyone looking for thoughtful, attentive allergy care in San Francisco.

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.
