    BAD BAD BAD BAD BAD BAD BAD BAD STAFF AND DOCTOR!!!!!!!!!!!!…read moreIf I could give a negative review I would. This is the second time coming here for my kids. The first time I called (2025) I was providing my information over the phone and the lady was extremely rude. Basically said I didn't have insurance coverage and wasn't able to schedule an appointment. I reiterated the fact that my children were covered and she needed to check her system thoroughly. Back and forth discussion that resulted in my calling back to schedule it when she simply could have scheduled the appointment to begin with and verified the active status of my insurance upon the appointment a month later or even in between that time. With her continued rudeness, I decided to give her a taste of her own medicine "no pun intended". She clearly didn't like it and coincidentally changed her attitude almost immediately. Upon arriving at the Doctors office, i found out that the rude lady over the phone was thinner short lady with dark mid-length hair. I don't recall her name at this moment. Fast forward, we entered the medical room. Dr. Koo kept interrupting me, dismissing my input regarding my concerns for my child and their health, and kept telling my young kids for them to explain themselves. I get it, you want to hear from the child directly how they feel but when they dont have the right words to explain themselves and articulate what is going on then thats when parents should advocate for their kids and speak up, which I tried doing. But again, Dr. Koo continued to ignore my concerns as a parent and kept interrupting me or basically shutting me up. I figured maybe she was having a bad day. giving her and her staff the benefit of doubt. 1 year later, another physical. Took my kids in and guess what!? YUP! Same BS! Same receptionist/nurse (whatever you want to call her) was rude. The rude lady was asking me what concerns i had related to my kids health. I explained and there was no empathy whatsoever. I felt like the concerns I was explaining to her didn't matter and tried rushing me by not allowing me to finish what i wanted to say and asked me "any other concerns" even before finishing my last sentence. If you dont know how to listen to patient's concerns, then this is definitely not the field you should be working in ... lady! She looked like someone put cat litter and fecal matter in her food with that snobby expression on her face! ugh! I hope she reads this too! Mind you, she also forgot to list some concerns i expressed. Anything i mentioned she immediately interrupted me by saying "You can tell the dr that, you can tell the dr that, you can tell the dr that." as if she didnt seem to care about what i had to say. I specifically asked for two specific exams and it was like twisting her arm! these exams i know for a fact she was supposed to do and didnt want to do it probably because she was being lazy. if your child goes in for an annual check up, anything can happen within a year so many changes, so you want to ensure you get EVERYTHING checked out! Not this office. NOPE! THEY DON'T CARE!!!! Once she left, Dr. Koo came in (shaking my head!) I started explaining the concerns. Guess what!? She did the same thing again as she did last year. Interrupted me, dismissed me, she was checking my child and made the comment like "what do i know im not the specialist". Right, youre not the specialist but you ARE the DOCTOR, so have some empathy lady!! Not to mention, my insurance fees pay your salary including my out of pocket expenses, so be grateful! I told myself I cant believe this! AGAIN!?!?!? this is ridiculous! Who does this?! what kind of doctor does this!? i was livid and so annoyed at the treatment we received, (better yet, lack of treatment), and couldn't wait for the appointment to be over with. Oh! and the two exams I requested, only one was done. Lo and behold, the one exam I requested, turned out my child now needs to be a specialist. If i wasn't persistent on the inhouse exam, my child would have suffered even longer!!!! SAVE YOUR TIME, MONEY, ENERGY, AND EVERYTHING OVERALL BY SELECTING SOMEONE WHO GENUINELY CARES!!!! FOR THE LOVE OF GOD DO NOT BRING YOUR CHILDREN HERE!!!!!

    Wish I could speak on Dr. Hsu however I never got to see her…read more Office doesn't answer phones, when I got frustrated and left an unkind message on my end, which I will admit wasn't my finest moment, I finally got a call back. They were however more concerned about the message than the medical care needed, stating they always answer their phones. Being more concerned about addressing the not answering phones comment than the actual medical emergency really says a lot about the staff. And they really don't answer phones because not even the insurance company was able to get through to them. Guess I really touched a sore spot there. Dr. Hsu should consider getting new staff unless this is actually a representation of her as a professional. But I've never actually been able to see her so I can't speak on her as a doctor. Such a shame. Update: I called multiple times so yes I did leave a voicemail with my information. Not only did I spend all morning trying to get a hold of you, but my insurance company tried too. They were met with no response as well and were very concerned that they changed my PCP immediately. When I got a call back it was because I upset you and I was never asked what medical support I needed. I was met with a "we always answer our phone, what do you mean?" So of course I was upset because I finally get a call back and it's regarding my comment. By this point, I had already changed my PCP and got an appointment for my medical situation. So, yes, I no longer needed your services. Regardless, I hope you can do better by your current and future clients. If you are unable to met demands it might be time to hire more hands or get a better system. My experience doesn't need to be everyone else's.

    Dr. Hsu is a doctor's doctor. She's smart, warm and has a passion for medicine and a passion for…read moretaking care of her patients. Highly recommended and she's got a strong following of other doctors and RNs who go to her as their primary care doctor. I can't say enough nice things about her and her staff. They're extremely helpful and efficient and return phone calls when you need them to answer a question or concern. Her office is like a Beverly Hills office in that it's a beautiful office and you'll walk in looking for the Nordstrom's piano player. It's that nice and extremely clean. Trust me you'll love Dr Hsu and her great staff.
