Even though there was a long wait, it was definitely worth it. Once I was seen by Sabrina, the…read morenurse practitioner, I never felt rushed and honestly felt like I was the first patient they were seeing that day. She was able to diagnose me, answered all of my questions, and made sure all of my concerns were addressed. She also took the time to explain my treatment plan and even talked through the possible reasons for how and where I could've caught it, which I really appreciated. Everyone was kind, thorough, and made me feel cared for. Overall, I had a great experience and would definitely come back if I ever needed urgent care again.

My dad have been feeling sharp pain in his heart. We were very concern and took him on a sunday to…read moreAp Urgent Care. We have been several urgent cares before and it's usually very packed and especially busy during the weekend. The wait time can be a few hours just to see a doctor. This urgent care is located right next to the Fwy. So it's very easy to find and plenty of parking spaces. I was amazed how empty and there was only 1 person in front of us. It took only 5 mins to check in after filling out all the medical paperwork. In less than 5-10 mins, a nurse already called us in to take my dad's health readings and immediately had a heart machine to monitor his heartbeat. In about 5-10 mins the doctor came in to check on my dad. Afterwards, it just took a little longer to wait for misc paperwork. I was amazed in less than 45 mins, we were in and out!!!! The facility was cleaned. They even have a security guard on site for our safety. The staff could also speak Chinese and overall they were professional and friendly! I highly recommend this urgent care vs going to an overcrowded facility which will take a few hours of wait and the more wait seeing the doctors and taking care of other misc items before you can actually leave!

I've been a patient at this office for years, and this was by far the most disappointing experience…read moreI've had. I received a call from the front desk today 4/8/2026 after I left my office visit regarding an additional charge for my consult I had paid $120 because I chose to visit their office while my new insurance kicks in, and the way it was handled was completely unprofessional. Instead of clearly explaining the reason for the extra $80 cost, the staff member came across as demanding and dismissive--as if I was supposed to already know their internal policies. At no point during my visit was I informed that discussing my symptoms could turn the appointment into a higher-cost consult. What made matters worse was the tone of the conversation. It felt like I was being blamed for the appointment running longer, which is unfair. Patients rely on medical staff to guide the visit appropriately--it's not our responsibility to manage time or determine billing classifications. There also seems to be a lack of internal communication and organization. If expectations, pricing, and visit structure were clearly communicated upfront, situations like this could easily be avoided. I asked to speak to the office manager because, yes, I had every right to be upset. Instead of taking accountability , apologizing, I was met with defensiveness--and then banned. Banned for speaking up after being treated poorly, advocating for myself. That tells you everything you need to know about how this office handles concerns. There is a serious lack of communication, organization, and basic respect here. If expectations and pricing were explained upfront like they should be, none of this would have happened.

He is too busy for his patients. Front desk acts like they are better than you the moment you…read morechallenge them and lose patience if they have to spend more than 2 min with you. They are also woefully outdated when it comes to technology. Who still uses fax and letters for updates. Aren't everything digital? It is 2024, not 2000. You have to call them to get any type of update but at the same time they are too busy to help you. Maybe you won't be so busy if you use modern technology or have some type of app to communicate. The nurse and aids also talk about your case loudly in the front office. Never heard of HIPAA? He may be fine for regular meds but he won't be able to help you if you have any serious illness.

This office is very busy and sometimes there is definitely a wait but the nurses and Dr Teng does provide excellent service. Their phone line sometimes are busy for half an hour and I can't get through to make an appointment. The office is very clean and Dr Teng is a very nice and patient focused doctor. I have never seen him raise his voice or get upset, super patient in answering all your questions and give you what you need, especially referrals to specialty doctors. My aunt had an eye problem and she got referred to one of the best at USC University medical center. Note this office is currently not accepting new patients as I was trying to refer one of my friends but she was turned down.
