I went in to see Dr. Reid because of some hives and my usual doctor was booked out far in advance. When I explained my situation to the front office staff they assured me Dr. Reid could assist in the matter. I had already seen my dermatologist, who has my trust and respect, and we agreed on the root cause of it. My dermatologist suggested seeing an allergist to see if there was anything further they could do. When I explained the root cause to Dr.Reid that once again, both my dermatologist and I agreed on based on the derm's other patients and my personal health history, Dr. Reid said "oh that's bullshit." Throughout our 45 minutes together he kept bringing it up as "bullshit" a total of 5 times. Not only are they unprofessional and disrespectful, but what's more worrisome is their completely dismissive attitude; for a doctor to not even consider possible root causes with data to back it up, is extreme cause for concern. They continued to speak poorly of my other medical doctors without even knowing them. Touting that "my primary and dermatologist should have been able to control my hives." But after doing what Dr. Reid prescribed for an entire week, I am still in no better shape. Lastly, he is a poor communicator: 1.) I didn't feel heard because I would explain in great detail "what happened" and he would immediately ask "okay so what happened?" and when I would ask him to clarify what further information he required, he would get irked at me. I've never had so much apprehension come from a doctor. 2.) He often interrupted me. He asked for my history of hives and when I would say "back in 2015 I tried this facewash and it gave me hives.." he would interrupt me to say "you can't call it hives because you don't know what it was." It was completely unnecessary and the third time he tried to interrupt me when explaining my history I finally said "OR whatever you want to call it." My medical team at the time diagnosed it as hives and it was treated as such, so constantly "correcting" me isn't fruitful. Needless to say, it was an utter complete waste of 2 hours and $40. I will never return.

Dr. Fast should be your first phone call if you have an allergy or immunology issue. Allergies and…read moreinfections can be misdiagnosed or ignored, with dire consequences and suffering if not treated early and accurately. I had a mystery pain that doctors could not figure out. Dr. Fast is smart and kind. She listened to my story for 5 min and was able to rapid-fire triage and provide a rare infection as a possible root cause. She proposed a simple test -- taking ibuprofen -- to confirm or rule out the infection. Imagine that -- instead of making me go get an elaborate, inconvenient, and time-consuming blood draw at a blood lab to confirm or rule out the cause, Dr. Fast gave me a free, self-administered test: take ibuprofen during a pain episode, if I don't have pain, it's the infection, if I still have pain, it might be something else. She is a genius with a big brain and a giant heart. For the Yelpers who didn't have the same experience, well, maybe they just don't understand competence and compassion when they experience it? I had to meet a lot of doctors in my mystery pain journey. Honestly, Dr. Fast is the best. She's a great communicator and one of those Harvard University/Yale Medical School/Stanford Medical School experts that could be talking on TV. In spite of the fact Dr. Fast could brag about going to Hahvahd, she keeps her impressive credentials to herself, is down-to-earth, is a great communicator with excellent bedside manner for all age groups and walks-of-life, including kids, seniors, young and middle-aged adults. Please google Dr. Katharine Fast and be blown away that the Internet agrees with me that she's the best allergy and immunology specialist in San Francisco and the Bay Area. You should book an appointment with Dr. Fast if you want an accurate, brilliant, approachable, and nice allergy and immunology expert on your side.

Dr. Andrea Yeung is an Excellent ear, nose, and throat (ENT) doctor. I was in dire need of a…read moreskilled ENT specialist. I had been suffering from a fungal infection in my left ear for six months, and my previous ENT had dropped the ball. Dr. Yeung quickly cleaned out the fungal infection, sent it for biopsy, and saw me four times every three days. Each time, she meticulously 'vacuumed' my ear. It was painful. Dr. Yeung was super efficient, gentle/caring, and she got great results. As well, her treatments helped close the hole in my middle ear. She also has great staff. I feel lucky to have connected with Dr. Yeung.

When I went to Dr. Yeung's office recently, I was told I need another surgery! Apparently, they didn't take out a bone in my nose that was blocking my sinus from getting out, and that is causing me having repetitive sinus infections over the years to the point that I'm on anti-biotics every 3 months. They never told me before/after my first surgery that was an issue, or else I would have told them to go all in and remove that bone and do a complete surgery/clean up. This is super frustrating to me, and hence the 1 star.

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.
