终于明白大家都给差评这专科医生，亲参经历。约了2个月来看专科居然不是这个地址，在现场打了10次电话都没人接，最后接了说取消我的预约医生不在，我还是叫儿子请假不上班开了来回1个多小时，还不肯给新地址我们，这是什么神仙操作？我还是第一次遇到，真的无语！美国居然有这样的专科医生？是专门坑人的吗？气死人专科没空就不应该接收病人的预约，我等了2个多月现在你们才取消，我还要重新换医生和预约，又要耽误几个月，病情都给耽误了怎么办，你们有没为病人考虑过？
They closed down without letting their patients know, I arrived for my appointment today. I've waited 4 months for this appointment since January, I can barely breath & swallow from a neck tumor. I will not only be leaving a review here, but I will be filing a complaint with the California medical board. No wonder why they have 2 star reviews. Completely & horribly unprofessional.
My wife had a 10:00 AM appointment today, March 13th, 2026, but upon arrival, we were told Dr. Tieng had not yet arrived. There were already five patients ahead of us, with an estimated wait time of 3–4 hours. Because we had to pick up our kids at 2:30 PM, we were forced to cancel. After seeing other negative reviews, we actually feel relieved that we didn’t proceed. Very disappointed in the lack of respect for patients' time.
my primary doctor referred me to this GI doctor but this doctor was very unprofessional they rescheduled me 2 days before the appointment, I already made the appointment with them 1 month or 2 months before but they suddenly rescheduled even on the same day but at a different time and i already have something to do in the afternoon.
It was a horrible experience with Dr Tieng both my egd and colonoscopy went horrible. I was not in a twilight. I choose her as I send my own patients to her. Never again will I recommend her.
