I had bariatric surgery done by Dr. Kwan last year. She did a gastric sleeve procedure at John Muir-Concord. The entire procedure was done with a robot in an hour. There was way less pain than I thought there would be. The recovery was easy and painless. I have lost about a hundred pounds. She is a very caring doctor and easy to talk to, I would highly recommend her to everyone.

Dr. Kwan preformed a robotic gastric sleeve surgery on me months ago. The care I received from her was amazing. Prior to my surgery she made sure I had a good understanding of what to expect. She has gone above and beyond in fallowing my care since the surgery. Her staff is knowledgeable and supportive. She gives extraordinary care and I have refereed several people to see her including my mother. Dr. Kwan has exceeded my expectations and the surgery is the best thing I have ever done for myself. Dr. Kwan is the best doctor I have seen!!!

Extraordinary is how I would describe my entire experience with Dr. Kwan and her staff. She was highly recommended to me for hernia repair and I can’t imagine having a better surgeon. She is very thorough in explaining everything about the procedure and made sure I had my questions answered. I always received an immediate response if I called her office with a follow up question. I cannot praise Dr. Kwan enough – she is very professional, smart, thorough and a very sweet person, too!

Dr. Kwan did a good job of explaining what to expect before surgery. The day of surgery I was well medicated for anxiety and pain and cared for by her team. Her training in robotic surgery made me more confident that I would get through without complications. After 3 days I was up and about and 3 weeks later I'm almost back to my old self.

I have unfortunately been treated for way too many conditions in my 73 years. Thus I am somewhat of an expert on doctors and their staffs/offices. Dr. Kwan is one of the very best. She explains everything and is obviously a very skilled surgeon. Her staff is excellent and I don't think I've every waited more than 5 minutes. The office was designed by a decorator but with input from the staff. It is extremely bright and cheerful.

Dr. Kwan clearly explained the procedure and recovery plan. I took the minimum amount of pain meds for a few days after the procedure and felt little to no pain after that. Dr. Kwan is an excellent surgeon and was very personable throughout the entire time I was under her care. I would highly recommend her.

Dr. Kwan removed my Gallbladder in late April. She fit me in quickly and took time to explain the process to me. Her staff and surgery team were very professional, helpful, friendly and reassuring. I had a bit of an ugly scar that a previous Dr. had left on my belly button and Dr. Kwan fixed it when she finished so I actually came out looking better than when I went in. The pain was minimal and I knew what to expect the whole way. She was AWESOME!

Dr. Kwan recently preformed hernia repair surgery on me. I’m 77 years old and was more than a little hesitant about it. She told me what to expect and answered all my questions regarding the procedure. The surgery went better than I expected. I experienced very little pain after surgery and am quite pleased with the results. She is easy to talk to and cares about her patents well being. I would highly recommend her and use her in the future if needed. All I can say is, she's good.

Dr. Kwan is a miracle worker. She performed my gall bladder removal surgery following my gall bladder attack. Beautiful surgical work with only four very tiny scars and I was back to work after only a week. Her care and patience when answering all my questions before and after surgery was reassuring and I whole heartedly recommend her as a physician and surgeon.

I had surgery by Dr Kwan two weeks ago. During the initial visit through my two week follow-up, Dr Kwan has been professional, compassionate, and thorough in all aspects. She has taken the time to fully explain what she would be doing and what I could expect both during and following the procedure. Her operating room team made me feel very comfortable, explained just what I would feel, and instilled a confidence that put me at peace. I feel extremely fortunate to have been referred To Dr Kwan.

Dr. Kwan is by far one of the most caring, knowledgeable and "GREAT" at what she does type of rare doctor you just really like and feel comfortable with from the get go. My mother had to have a mass removed from her leg and she absolutely loved Dr. Kwan. Prior to surgery my mother was always in pain and now post surgery she has NO pain at all. I highly recommend Dr. Kwan to anyone looking for a GREAT doctor. My mom said it best, she was the light in our darkest moment. Thank you Dr. Kwan.
