Dr Paul Sun was great with me. Not only did he do a great job of emergency care and surgery at Saddleback Memorial Hospital, but each time I had a question, his office contacted him, and he got right back to me. I am feeling much better, and I would highly recommend him.

Amazing doctor and staff!!! The wait was minimal, the doctor was thorough and listened to my concerns. We worked together to come up with a plan for the next steps of my care. Check out was a breeze. My referrals were submitted quickly and I was contacted right away with the information. I have nothing but great things to say about this office.

I simply cannot thank Dr Yian enough for his kind advice and thorough guidance vis-à-vis my current nose-related difficulties, especially with regard to normal breathing, and of course for his patience.

Oct 26, 2021

Hey, no one really likes going to doctors. No offense is meant. It's just a fact. Since we live in empty shells that fall apart, we're put in positions that compromise the way we look at things in life. That's basically where I'm at today having been diagnosed with cancer. That said, the service I've received since then has been done, I'm assuming, according to protocol. Since I've never really been in this position before, I can only hope that continues, and I'm not just another patient in a string of patients, which it feels like sometimes. Thank you for your service. It is appreciated.

Oct 22, 2021

I have been visiting Dr. John Sun for a couple of years now. I like the way his office sends me reminders of appointments, the minimal time spent in the office waiting for the appointment and the ear wax removal process. I am very satisfied with the results.

Thank you again for an effective diagnosis and treatment. This week you installed a drainage tube in my weakest ear and it helped it immeasurably. I can hardly wait until you can also do the other one. It has solved the feeling of isolation that I had because I couldn't hear what was going on around me. I am grateful to be able to communicate

Sep 15, 2021
