I'm very happy with the care that I've received for the last 10 years for my child with a heart condition that we've experienced at the age of 3, and they've done a wonderful job. They've never made me feel any insecurities. They've, they're awesome people. I appreciate everything they have done for us. Thank you.

Excellent - wish we could get all the care from UCSF for this particular issue rather than having to coordinate with Kaiser.

I was very pleased in my visit. Please, remind your fellows of minding their bedside manner I know they are still learning but it felt like they were pushing for answers but not acknowledging my responses.

We came from overseas and FTE initial online application for an appointment was lost somehow, which I didn't know until I finally called after a couple of weeks. That was a bit of a problem. However, once I was connected to the international medical service, the staff worked very hard to arrange the appointment, about which I very much appreciate. Once I arrived, everything went very smoothly with very little waiting time. Lastly I really like the MyChart feature. It was a little bit tricky to get it set up, but very useful once the account was set up.
