Verified Patient Reviews
Would definitely recommend! I hadn’t seen a dermatologist in a long time, and Dr.Kwan was great with my needs. I waited less than five minutes, and everyone was very nice.
He comes highly recommended but did not listen to what I was saying about my skin and its reactions to certain products and insisted that I try an Obagi product that contained retin a which is awful on my skin. I did not feel like he was listening to my concerns.
Doctor and his staff very professional, cordial, caring. They exceeded my expectations. Welcoming atmosphere, comfortable waiting room, but they don't make you wait long so get there early to enjoy the environment.
Really took my goals and preferences into account to design my treatment plan. I felt listened to and supported in my decision making.
Doctor is very professional, and friendly. Efficient and helpful staff.
Exceptional service and professional combined with outstanding knowledge and care.
Always swift and professional....Synced like a perfect Swiss watch!
Dr. Kwan did a thorough cancer screening and made time to address all of my concerns. The office is very modern and fresh.
Straightforward, kind, and answered all my questions!
The office is really nice, and everybody was very professional. Highly recommend them!
Nice offices - took care of all my issues in one visit.
He was very straightforward about how long the treatments would take to affect my skin. As a 24 year-old, I had acne for the first time in my life due to a change in birth control, and it was horrible. It took some patience, but Dr. Kwan found the right combination of treatments to clear my skin up and it's looking great!
He is the best - thorough, talented and as nice as can be. Staff is superb as well.
I am so appreciative of Dr. Rupa for seeing me at such a short notice. Very short wait period and is to the point. Highly recommended
Seems very trustworthy. didn't push anything cosmetic on me at all until i asked.
Excellent visit. Best experience with a dermatologist to date.
Really enjoyed meeting Dr. Kwan.
Great staff, helpful doctor, beautiful office.
Great visit. The office is modern and incredibly professional. Dr. Kwan was helpful in answering all my questions, as well as providing suggestions of things to look out for. The staff was incredibly pleasant.
I felt that Dr. Kwan didn't look at my skin. He had a plan of what he wanted to do before even seeing me. I felt that the plan was probably the same plan that he gives to everyone else with my condition and was not personally tailored to my health goals or needs.
Dr Kwan helps me to not rush and jump to laser treatment ~ instead we have an agreement on follow his prescription and routines to tackle with my current active and scar issue. He is very friendly and I feel comfortable and reilable of how efficient and knowledgable their nurse and aesthetician. I would like to follow what they have been told so and hope to change the texture of my skin to more healthy looking:)
Dr. Kwan is very pleasant and professional. Unlike a lot of physicians these days, he actually took the time to listen to my concern and thoroughly address it. The office and other medical staff was also very nice and provided detailed information about treatment options and the processes. And being brought in to the exam room right on time was a bonus. Great first experience with this office.
Spiffy office, central location, short wait, and nice, attentive staff. Dr Kwan seemed knowledgable and nice. Didn't feel rushed. Nice duds on Dr Kwan too!
Dr. Kwan and his staff have a gift for making patients feel at ease. Great visit. Great doctor. I am happy to recommend him.
Thorough, thoughtful, efficient.
Dr. Kwan is the best there is!! He is a fantastic doctor and an amazing person. He is "5 star" among 5 stars!! There is no one better!!
Dr. Kwan is extremely professional and knowledgeable and was able to go through my skin screening very quickly without it feeling at all rushed or impersonal. I had one area that he wanted to check out (very simple procedure) and he offered the option of taking care of it within the appointment or rescheduling. Since Dr. Kwan is booked about a month out, I opted for having the procedure done immediately. It was quick, relatively painless, and I felt relieved. The nurses and receptionist were also extremely personable and made me feel at ease even though this was my first appointment with a dermatologist. I highly recommend Dr. Kwan if you're looking for a dermatologist in San Francisco.
Great as always! Takes care of business right away.
The spa atmosphere is not my cup of tea but it was an efficient, on time visit and the doc had time to discuss issues. He was very clear, and on point, only possible concern is that he focused on the areas I brought up to his attention but didn't do a full check-up himself possibly discovering things I'm not aware of.
Super friendly and informative. His staff were great as well. Overall wonderful experience, I'd highly recommend him.
Wonderful! He spent a lot of time listening to me, my reasons for the visit and my preferences in terms of next steps. Plus, his staff is amazing.
The Doc was very nice.
Wow, I didn't realize how awesome it would be to see a Dr. Kwan, get diagnosed, and treated all within 5 minutes. The office is pleasant with courteous staff and very clean, modern decor.
liked he and his staff...was out the door in 15 minutes
He was very knowledgeable and the office was probably the coolest medical office I've ever been in.
Dr. Kwan has improved a lot since my earlier visits (about 2 years) He genuinely cares about his patients and does very well in explaining. Enough said, he's my best doctor and I will stick with him for as long as I need him!
Dr. Kwan was fantastic! He was super warm and communicative, and he even found a way to bill my insurance to zap a few veins off my nose. Will absolutely be going back the next time I need a dermatologist.
Nice staff and doctor
I had a very good appointment with Dr. Kwan. He was very thorough and straight and to the point, but also listened to all I had to say, had a good bedside manner, and makes himself available for any further questions and issues. I had no wait in the waiting room either, and the rest of the staff I interacted with was also pleasant. I would definitely recommend Dr. Kwan for those looking for a Dermatologist.
I was very happy with my visit. I was greeted with a beautifully designed office, friendly staff and very kind and knowledgable doctor. My appointment was exactly on time. He walked into the exam room at 9:15 on the dot. This has never happened to me when visiting a doctor's office!
The many assistants were welcoming and helpful. I liked Dr. Kwan. He was patient with my questions. My face has many red bruises; I await the results; however, it looks like some of the capillaries are still visible.
He is brilliant. Very friendly, helpful and knowledgable. I love how his office is electronic it makes everything much easier. This is how all doctors should be.
Great visit. Very professional, extremely thorough.
Great! I felt comfortable and felt like my concerns were addressed. I like that he took the time to listen to my concerns, and he was realistic about how long it would take before I noticed a difference in my skin. I am super optimistic about my treatment plan and look forward to seeing the results!
I was frustrated that they didn't read the information I entered about why I was coming in for a visit. They ended up making it work but the situation could have easily been avoided.
Quick, efficient and thorough, yet not rushed. Felt like he addressed exactly what I needed without delay. Hopeful that the results will be positive!
My first visit with Dr. Kwan went very well. The front desk staff acknowledged me right away and I only wait for about 5 mins before a nurse called me into a room. Dr. Kwan showed up shortly after and was very approachable and knowledgable. I really like how he gave me samples of different brands to try before I make larger purchases.
Doctor Kwan is an excellent doctor with an outstanding staff. He knows his stuff an has a friendly yet professional manner. An all around good guy.
He was nice and I can tell he is probably good, but he is too tentative. I wanted to remove some sun spots and asked about laser removal. He ended up giving me a topical treatment. It isn't working and I don't have the patience. Probably won't go back since he didn't listen and his solution didn't work.
Super nice doctor! The office was so modern and clean. I felt like I was at a spa or a trendy salon vs. a doctor's office. Will definitely come back!
I had to switch doctors when my firm changed health insurance plans, which can be a bit of a crap shoot. I was very pleased with Dr. Kwan and will continue to see him. Friendly, professional and knows his stuff.
Very professional and genuine in questioning and recommendations!
He is both professional and polite and knows his business!! I feel really comfortable with him.
Doctor Kwan was very pleasant and my appointment was over in 10 minutes!
Does not hurry you through a consultation.
Great experience, very friendly and makes you feel comfortable right away. Was able to make a quick diagnosis on a skin issue that no other doctor I had been too was able to identify.
dr Kwan had very good manners, very listenning person, i just move in town, and very happy to find such a good physician!!! the office is very clean and update. i will return for sure.
I was in and out in less than 10 minutes. He was kind and professional, took care of all of my concerns and boom. done. Thanks Dr. Kwan!
Dr Kwan was timely, quickly diagnosed my skin condition, and explained my treatment options. I would recommend him to my family and friends without reservation.
Dr. Kwan was very helpful and answered all of my questions.
Very nice, gave me lots of samples and was very helpful
Dr. Kwan was great. I don't think a visit to the doctor can get any better, unless they read your mind and get your medical history. (As it was I filled out a quick form on an iPad.) The office also looks and feels like a high end spa.
Personable, quick, efficient, resolute.
Great dermatologist - great bedside manner, very knowledgeable, and took the time to explain exactly what my issue and course of treatment would be.
Great first visit. Very knowledgeable and puts you at ease.
Great experience with ZocDoc and Dr. Kwan. I got an appointment right away, didn't have to wait, and got all my issues taken care of.
Would definitely recommend
Mr Kwan aws truly professional anda gave me right feedback
This was such a great experience. Dr. Kwan and his staff were all amazing, efficient, and extremely professional/knowledgable. So glad to find Dr. Kwan! Thanks to ZocDoc for making the appointment scheduling so easy!
Easily the best derm in the city
Dr. Kwan was great! Wonderful bedside manner and very helpful.
he was professional, knowledgeable, friendly and extremely efficient. probably the best dermatologist appointment i have ever had, and i've been to many!
Very nice office, sweet doctor and a very efficient staff.
Dr. Kwan was great. He was very helpful and provided tons of information. He gives a lot of insight in to why your skin is the way it is and does everything he can to get you free samples and save you as much as possible. Also worth noting: his skin, and that of all the people working at his office, is magnificent.
Always a gentleman, Always calm assuring...love him!!
Dr. Kwan is great. He always listens to my concerns and gives me great advice.
I found Dr. Kwan to be warm and engaging. I came to him with a melasma problem. He could have easily convinced me that I needed expensive laser treatments, however reassured me that topicals were the best route for now. Instead of busting out his script pad, he encouraged me to use hydoroquinone that I already have & samples that he provided. Dr. Kwan is a kind, competent, ethical dermatologist. Already looking forward to my next appointment!
He was awesome! For the first time I didn't feel rushed with a dermatologist visit. He would listen to my problems and answer my questions. I thought he was very sweet and gentle.
It was so easy and relaxing No stress Thankyou dr kwan
I'm very happy, I left with hope.
Very nice man and honest about the results that he can achieve.
Friendly-Fast and efficent! :-)
Very knowledgable in his field, I totally trust his diganosis.
wonderful! Look forward to a long and beautifying relationship.
Very quick, easy and comfortable. Dr. Kwan was very knowledgeable and easy to speak with.
Great experience; nice office; nice doctor. Would recommend him.
Dr. Kwan was very professional and engaging. I did feel however; he was in a bit of a rush even though I was on time for my appointment. I also came to get a skin screening and acne consultation and was told I could only get one at a time and that I would need to book a separate appointment. It's not easy to get time off work and I wish that someone had communicated this to me when I called to make the appointment. Either way I left happy and have recommended him to a few people:)
Dr. Kwan has the perfect attitude with his patients - he is friendly yet professional, and seems to genuinely care about you. He is clearly an experienced practitioner, having diagnosed my dermatological issue immediately. Dr. Kwan's practice goes above and beyond in their customer service, which is so rare in the healthcare industry these days. I would recommend Dr. Kwan to anyone in search of a new dermatologist!
Dr. Kwan and his staff are friendly and professional. The office is new-age with whites and fogged glass, which makes it feel more like a spa than a doctor's office, but they had me fixed up and out of there faster than a taco bell drive-thru! I would definitely recommend Dr. Kwan.
