Outstanding Caring Surgeon
I had Gastric Sleeve and Hiatal Hernia surgery on September 29, 2020. After doing a lot of research on surgeons, I choose to contact Dr. Kwan. From the very first appointment, I knew she was the surgeon for me. Dr. Kwan is very easy to talk to, communicates thoroughly each step of the way and makes sure that you fully understand the entire process. She never hung up on a telephone appointment until all my questions were answered. Her staff is also top notch and made the entire process so easy always staying one stop ahead of me with appointment and answering questions. If you are looking for a compassionate, skilled and thorough surgeon, Dr. Kwan is the one for you.

Simply outstanding
Had RNY and hiatal hernia repair in Nov 2021. Dr. Kwan has been very supportive, and clear about the process every step of the way. She prepared me with plenty of pain medication for after surgery, well, her surgery was so precise that I never, not once, needed to take any pain medication. This surgery was absolutely painless. I guess I can say, everything turned out perfect! I am currently at 125lbs. and could not have done it without her support. She does video visits, which I prefer, because I do not like driving. She takes the time to respond to all the multitude of questions I always ask. She is very knowledgeable, and always shares important information such as support groups or other pertinent information to help this be a successful surgery. Thank you very much Dr. Kwan!!!

Dr Kwan and her staff were very professional and full of information and encouragement! Bariatric Sleeve Robotic Surgery went home next day and the five little holes healed great with the glue and have not had one issue after surgery!! Thanks to Dr Kwan and the journey they take you on to get to the Bariatric surgery recommendations you and Dr Kwan agree on. Awesome is all I can say.

I went to Dr. Kwan about a hiatal hernia. Given my issues with weight she shared with me an option for bariatric surgery and she and her staff worked with me over many months to answer questions and make sure I was prepared. I couldn't be happier with results and availability of Dr. Kwan and her office to help with any post surgery questions or concerns.

I have just had my one year post op appointment. She is amazing weight loss surgeon. She gives you all the tools u need to loose the weight. She also gives you all the sample menus ideas you need. I have lost a total of 127 lbs in one year. I fully recommend Dr Kwan. I have also had zero issues. My only regret is not doing it sooner.

Dr. Kwan offers LINX ®, a new laparoscopic procedure to treat GERD. This procedure involves a string of metal beads that are drawn together by a magnet. When this string is placed around the lower esophagus, the magnet pulls the beads together and closes off the esophagus from the stomach.

Dr. Kwan was my doctor for a Barbaric Sleeve Surgery that I had in January 2020. I am very happy with the surgery, I have lost 90 lbs. so far and hope to take off more. I have kept the 90 lbs. off during the pandemic. The only "side effect" that I had after the surgery was being nauseated which I am told happens to some people. I let Dr. Kwan know and she gave me medicine to help me out, it eventually went away. Dr. Kwan and her staff were very helpful, I have never been sorry I had the surgery and recommend it for anyone that has had years of trying to loose wait and keeping it off.

Dr. Kwan did my bariatric sleeve surgery in 3/2018 and removed my gallbladder in 12/2020. I'm a person that does a lot of research when I get significant medical advice...especially for surgery. Dr. Kwan answered all my questions...she did not "brush" them off. She took them seriously and gave me clear answers. Sometimes that meant waiting to see how I healed and how I followed directions. I followed all her pre- and post-surgery orders and suggestions, which I think re-enforced a path for recovery, weight loss, and just being healthier. Both surgeries went just as expected. I think it helped that I went into both surgeries feeling positive about the outcome because I was confident about my surgeon's expertise, skill, and care. I recommend Dr. Kwan without reservation. Her team only makes things even better. They are extremely patient, knowledgeable, and very helpful. They really helped me set up some complex logistics during COVID-19 restrictions. THANKS to ALL!

Dr Kwan was my surgeon for bariatric surgery, vertical sleeve. I recommend this surgery for anyone sick of carrying extra weight. She helped me loose 50 lbs safely. It was a little hard to understand the staff positions, who to call for what and when. But, they are ready to do the hand-holding necessary for new patients learning about their new stomach. Insurance issue cleared up easily. John Muir Hospital was safe and great.

I don’t know what happened but my GI surgery with Diane Kwan went horribly wrong and now I’m very sick because of it. It made my acid reflux worse, not better. My esophagus is so damaged I’m scared I’ll have to have it removed. I also now have IBS and food allergies I never had before the surgery. The food allergies cause horrendous asthma attacks if I eat something that I’m now allergic too. My GI doc said my internal anatomy is seriously messed up. She didn’t seem at all sympathetic when I told her what has happened. Please pray for me!

She came off as knowledgable and kind. I was wrong! She recommended surgery for my son (probably money driven) surgery was done and wasn't done well. His wound was not healing at all.. We made several calls to Dr. Kwan , which was ineffective. His wound was open ,huge, painful, and stinky and she still was not concerned. She said will see you in a week. Really? Finally took him to urgent care, since she DIDNT CARE, and Dr. There said it was a surgery gone bad. He now has a staff infection and hole within a hole. This Dr. Kwan has damaged my son and is not kind and dosen't care. This will effect him for the rest of his life.

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!!!
