I saw Dr. Diane Kwan in June 2025 for a suspected hernia above my belly button. She diagnosed an umbilical hernia and confirmed it with an ultrasound, which clearly identified the hernia in the exact area where I had pain and a visible bulge.

I’m going to try and not get emotional while typing this review…Dr. Kwan performed a hernia surgery on my husband last month. This is the second hernia repair he has gone through. The first surgery was performed 7-ish years ago by a different doctor.

I honestly just love Dr Kwan she is an amazing human being she is kind, gentle and understanding . She truly cares about her patients . She did my gastric bypass and I’m feeling amazing and it’s only been 24 hours! I highly would recommend her.
