He's very efficient and intelligent. Office work staff can be slow but they will work it through for you.

I went to the clinic today to pick up my results, but I was completely unprepared for just how terrible the doctor's attitude and the quality of service would be. read more

Would give a zero star if I could. DO NOT come here unless you want to be mistreated. This clinic has a huge ethical issue as their terrible receptionists often give attitude when patients have any questions or concerns. Nurses don't show respect or compassion when patients share their symptoms and experience. To all the people who work in this clinic, especially Jacqueline Tran (P.A) you shouldn't work in healthcare if you lack kindness, patience, and sympathy. read more

Incompetent and unhelpful practitioners. My dad needed a practitioner's signature for his disability benefits. Despite having significant mobility issues and being forced to carry heavy objects for up to 10 hours a day, the practitioner refused to sign the form and behaved in a condescending manner throughout the process. I don't recommend this place at all read more

Worst experience. Reception is horrible. Waiting is so long. Some staff don't speak English. They give you results and don't give you options of what to do. read more

We only get to see the doctor for check up once a year. We have seen by couple doctors in here, my favorite was Dr. Daniel , but he's no longer here. Dr. Tuan Le is the least helpful. Anyways, this place is horrible in term of calling for lab results. They didn't call me for my lab result. They called my husband, he didn't pickup but they never left any message. I looked at his lab result and see the number of his cholesterol is so high. I told him to call the office back and asked. They told him that he needs to come in and see doctor. What???? And you never left a message to tell him to do so??? The staffs here are not helpful, please don't schedule with any doctor in room 102. Both doctors and staffs are horrible. I'm looking to find another doctor!!! read more

I got my glasses prescription here and I can't see clearly at all with them. Whatever they measured was completely off. Very disappointing and unprofessional. Waste of time and money. read more

I dont know how this place is still in business. The zoo is more organized than this place. Appointment at 11:45. We didn't leave until 2:30 for a simple XRay. What a joke. Everyone here hates their job. Such a miserable place. read more

Recommend this place Floor3- Lilly. Thank you Lilly for helping me with the insurance. Appreciate it read more

Tiếng Việt & English Definitely worst medical experience anyone can ever have by a long shot. I never imagined how bottom of the barrel service this place provides until I experience it first hand . It's a miracle this Michael Dao asshole is still allow to practice medicine. Treats his patients like absolute garbage, doesn't actually ever diagnose people for what they're in for, rush every meeting as much as possible like it's a damn fast food restaurant. I truly believe this place only exists to farm government insurance (Medi-Cal) off of poor non-English speaking people. If you saw Michael Dao diagnose a patient without knowing he's a doctor before hand, you might think that he's circus clown doing a bit. Michael I hope it all catches up to you and your facility gets shut down forever for good. Please if you ever thought about coming, consider my review, don't come. You can probably tell from other reviews that this place has a painfully long wait time for anything, getting meds or getting service. It's not worth your time or dignity. Come here if you want to die instead of getting treated. Trung tâm y tế Michael Dao là nơi tồi tệ nhất mà các bạn có thể tưởng tượng tới. Bác sĩ Michael Dao là một con người người vô lương tâm và vô trách nhiệm. Chỉ có mục đích là kiếm tiền và không hề quan tâm tới sức khỏe của bệnh nhân. Bác sĩ gì mà không bao giờ chịu nghe bệnh nhân khai bệnh, chỉ giỏi cái cắt lời người khác. Bất cứ bệnh gì không quan trọng, 10 trên 10 lần bác sĩ Michael Dao sẽ giao thuốc giảm đau thay vì thật sự trị bệnh. Cách bác sĩ Michael Dao đối sử với khác hàng (bệnh nhân) chẳng khác gì đối sử với súc vật. Mình thành thật khuyên các bạn đừng bao giờ đến chỗ này. Nếu bạn nào đọc được Tiếng Anh thì xin hãy đọc phần trên của review mình. Mình cảm ơn và chúc sức khỏe. read more

Im tired of seeing elderly got yelled at by the receptionist whenever i go there with my grandparents. Anh you know whats worst? They have new receptionist team which is the same age as me! Probably not over 22 years old but they still act the same as the old ladies that been there. RUDE, UNPROFESSIONAL, NO MANNERS. They rolled their eyes whenever someone ask them to DO THEIR JOB! I beg my family to go to other clinics since we have plenty of viet doctors in the county now. And sure I will make them so! Save your time, and protect your elderly in your family they been treated horribly here. Mine were having me with them or else im not sure what gonna happen with them. read more

Please don't go here. All I need was a prescription refill and the ladies on the phone kept saying I had to come in. I told them I lived 2 cities away and I'm not coming in for just a prescription refill. Especially when it takes hours to see a doctor. Then they told me it's not their fault I live so far & that the doctor was on a 3 hr lunch break. I called multiple times throughout the week and the doctor told me I didn't need to come in and to just call for a refill from my appt with her the week prior. So I don't understand why it's so difficult for them to approve of it? This place does not care about their patients at all. Their staff have a lot of attitude and are rude as well. I've been here since I was a kid and honestly I've stayed at this clinic because I liked one of the female doctors I've been going to however she recently quit so I will have to find a new clinic. Service here takes forever and the aunties in the back gossip all day about patient problems. read more

Oh man...wish I had read the reviews before scheduling the appointment with this office. The appointment is at a later date, but they have already charged us $200 for the Covid testing. We were given the option: 1) pay $150, get the results in 2-3 days or 2)$200, get the results within 24 hours. Because of my working, I opt in to get the fast results. My 2 star review is solely based on the fact that during this pandemic, they charge you before rendering service. Although, there has been articles where he offer the service for free or even at a much lower cost. Will update you guys on the result after my appointment. read more

Horrible experience! The worst medical service! Please save yourself time and troubles and go find a better doctor elsewhere that provides excellent health l care services! read more

See attach picture. Don't wasted your money going here paying for the not approved & not accurate tests safer to stay home, social distancing, & wash your hands. STOP scamming your own people ‼‼‼ read more

If you are looking for a good or decent doctor then don't see Dr. Michael Dao. I took my dad there and the doctor's bedside manners are one of who doesn't care for the person instead the doctor only care about money. The doctor did a rush incomplete examination and didn't even examine the issue that my dad was trying to tell him. The aggressive violent motion the doctor performed on my almost 90 years old dad's legs make me cringe. Luckily my dad has strong legs and was not hurt. The doctor also didn't give us all information until I asked and tried to get my dad to agree with something without full information. The doctor yelled in my face when I told him to hold on about sending my dad somewhere because I knew my dad didn't fully understand. I tried to explain to my dad about what the doctor wanted to do and the doctor again continue to write in the records while I'm explaining to my dad so I told the doctor to slow down and the doctor yelled at me to slow down. The doctor also took a personal call while examining my dad. Seeing my dad is having a hard time walking you would think the doctor would not pull on my dad but the doctor did. My dad even told the doctor he feels like he's going to fall. The doctor just laughed it off. On a rating of 1-10, this doctor would get a minus 100. You can tell he does not care. Don't waste your time! read more

Waiting almost 2 hours for appointment. 2 hours to get medicine. Terrible service. Wish they are not over book

there is this ONE receptionist that is so incredibly rude. she always acts like im bothering her. sick to see a lack of empathy in a medical field. wonder how she will treat her patients lol read more

Terrible service. They require their patients to come every month for refills and they never respond to pharmacy requests. My parent almost died from his care. I don't want to give specifics bc my parents don't realize how bad this Dr is and continues to come here. read more

I'm surprised this place even get 2 stars lol it's a joke! 90% the staffs are ALWAYs unfriendly and not helpful at all. Took my mom there today at 4;30 literally no one there was helpful and when we asked questions they give her nasty attitude. The owner Need to train your staffs better.. smh wasting my time to even write this read more

As someone that felt very worried for my health and moved from doctor to doctor to find someone that could not only treat me well but also understood me, this place is literally the bottom of the barrel. I would most definitely say that if you want to come to a health clinic that specializes in making you feel so much worse about yourself, mentally and for your health, this place is it. I came by for a health checkup and previously having been scouring for doctors that understood me and validated me for my health concerns I thought I might give this place a go. Instead, I got an experience of a lifetime. I'm being very sarcastic when I say this because not only did they accuse me for their own disorganization and calling me a liar for telling them them that I had already previously signed up for a health program WITH THEM THERE, they yelled and accused one another (including me) on who lost my file. This whole experience felt so surreal and utterly ridiculous as I was sitting in the patient room while this whole altercation was happening since I was literally only 18 and already scared for my health. I'm just going to say I came out of there with tears and in the end, it was a whole miscommunication and lousy organization on their part that was at fault but that really doesn't erase this experience. As someone that is Vietnamese, don't go here if you want to go to a clinic run by rude Vietnamese aunties who only care about the next paycheck. read more

This is specifically for room 101. I've been here several times for minor things such as the flu, vaccine, etc. No matter what day or time I come, I have to wait over an hour just to be seen. The LVN and receptionists are constantly gossiping and arguing with patients. No sense of customer service whatsoever. Recently, I came in because I got bitten by a stray cat. Got my vitals taken went back to wait. Finally saw the doctor and I told the doctor I got bitten by a stray cat. He then says, "okay...so what do you want to do?" Really? You're the doctor! Not once did he look at the bite to see if it was swollen or infected. I then told him I wanted antibiotics and a tetanus shot. He said "okay. Go bring this to the pharmacy and they'll give you the tetanus vaccine, bring it back and the nurse will do it." This place is horrible. Seems like they care more about the reps coming in and putting on a show than actually providing care to patients. read more

Stay away from this place . The doctor don't give a crap. All they care about is losing their license . Forget this place . Go find someone that actually cares ! Can't even follow a simple discharged paper from UCI! This place is horrible ! For sure not taking any of my family members here ! STAY AWAY !! Appointment at 11:45.. I'm out at 2 something just to get half of my meds. read more

Thank you so much to Dr. Michael Dao He is a good doctor. He was so kindly and help everyone with his heart God bless him read more

They have THE WORST customer service here!!! This medical group has always dissapointed me from time to time. Staff are unfriendly, talking shit with each other, unprofessional and plain rude, they don't care about you or at least be nice to you. Their way of working is getting as much as money out of you or your insurance. They are greedy, immoral and disgusting people under the name of doctor. They will not care if you are in a bad condition and ask for medicine, they want you to come back so they will take more money out of your insurance, they even ask you to pay cash only to avoid tax. DO NOT COME TO THIS MEDICAL CENTER if you really care about your well-being and your parents... read more

Been coming here for over 10 years due to medi care insurance. Seen a fair amount of the crappy physicians on rotation. Absolutely most unprofessional and uneducated is QUANG BINH NGUYEN MD. Beware of his care provided to you, not to mention how unprofessional he is as a doctor and as a person who is representing this company read more

Flu season is here, and these assholes are back at it again to take advantage of people. If you want your flu shot, then go somewhere else. The long wait will probably get you sicker than before you came in. The nurses are jerk. Don't ask unless you want to extra terrible service. Don't believe that they are actually working on anything. They are just gossiping and trash talking. You will be ignore for sure. Who cares if you are sick or dying. read more

my problem : receptionist said that i can come and take the third shot of hpv and i come to take the number and sit to wait. then when i am coming in, they tell me that my document was expired. its so super bad service here, they did not tell me to wait for the agreement , i have to come and when i told them , they tell me that another girl said not anyone take the responsibility . omgggg!!!!!!!!!!!!!!!!!!!!! change where you take doctor right now read more

So bad khi lấy appointment ở đây. Lễ Tân thì nói chuyện nh ăn cớp rồi cúp máy cái rụp. Lấy hẹn khám tổng quát mà lấy cho khách lúc 4 rỡi chiều, tới ni khám xong thì bác sỹ bảo chỗ thử máu nghĩ rồi, chổ siêu âm củng nghĩ rồi, chổ thử hi thở cũng nghĩ rồi . Nói chung tới chỉ điền thông tin rồi bác sĩ hỏi vài câu xong cái éo gì cũng close. Thế tới khám đc cái éo gì chỉ tốn tiền khám rồi đi về. Lễ Tân làm hẹn ở đây có bị thần kinh ko, Ngu ngục đến thế là cùng. Will never come back. read more

They withheld information from me about my results over the phone. Given they did ask me to come in but said it wasn't serious. I had found out after going to another doctor that it had been serious, which they should have said over the phone instead of keeping it from me! read more

This doctor is a crook. Scamming people to charge $49 for Covid19 test kits that has been made in China from Korea and had not been approved by the FDA or CDC. He's later on changed his tactics by giving out for free to anyone who can't afford it because the FBI was looking into his business. His office employee are rude and unprofessional. You can look into his education background and you will find this guy is graduated from some medical school in the Caribbean. He's making his living out of all low income patients who are mostly on assistance from the government. read more

The imaging center here is horrible in terms of customer service. The receptionists were busy chit chatting with each other. My mom went here a couple of times and she had to wait for at least 2 hours to be imaged each time. It's ridiculous. They don't care about your time even though you come early or on time. My mom had to go to work so she had to leave after waiting for almost two hours. It happened at least twice already. We will try to find a better place that would take our insurance. DON'T GO HERE!!!!! IT'S HORRIBLE!! Super unprofessional.... read more

There are many great doctors, PA, and NPs. My primary doctor is Helen Do, she is a NP and all she cares about are her patients. She can spend a lot of time and explains whatever you don't understand. Before, my other doctors were to lazy to explain and they would not spend for five minutes to talk to me. I like Michael Dao group and specially Helen Do NP. read more

This is the most horrible, unexperienced, greedy medical clinic EVER. I have diabetic and I came in check up, they sent me to Labcorp for blood test and after I received a bill for over $1000. I am confused since I have insurance, why would they requested blood test for me if my insurance doesn't cover. I went to the doctor for answers but they were rude and mean. They are irresponsible, unethical and unwilling to help resolve. Please save yourself and your family from dealing with headaches this medical clinic created. The medical board should audit them. Should read his review on Yelp before sending your parents here. read more

Unorganized. Unprofessional. I went to the office to get a check up for my back being in pain. I gave the nurse my ID and she gave me paperwork to fill before I could get my check up. After filling out the paper work I waited an hour just to be told I'm in the wrong office because I was a minor. They had my ID the whole time, shouldn't they check that first? Then I asked if they could reserve an appointment at the same time in another room they said that I would have to schedule a new one. I ended up not getting a check up that day and the earliest appointment was the next week. I would not suggest this doctors office. read more

This is a medical clinic that have multiple doctors. This negative review is based solely on Dr. Anh Thu and their billing department lead, Jessica Nguyen. As a patient, you would hope that your primary care physician care enough about your health at a minimum. Instead, Dr. Anh Thu treated my mom as her experiment by prescribing Cologuard, new method for colorectal cancer screening (from Exact Sciences). Once result came in, the Dr./office didn't bother to contact my mom to provide her the result and/or request her to come in for a follow-up appt. On top of the poor follow-up skills with patient(s), insurance company does not cover this method stating that this is considered "experimental" compare to the traditional method (which is covered by all ins. co./Medicare/Medi-Cal, etc). Besides this, the Dr. billing dept. didn't bother checking with insurance co. on behalf of their patient in advance to see if this is even cover (probably getting some kind of kick-back from vendor...assuming). Unfortunately for my mom, she have PPO so no authorization is needed (wish she have HMO in this case). What make me furious is that I had to contact the office multiple times on different occasion (at least 4x...e.g. in-person & calling) to get assistance and yet I barely had any help. My only request from Dr. Anh Thu was for her to provide me a "Letter of Medical Necessity" (required by my mom ins.) to explain why she/Dr. chosen this method rather than the traditional one to submit it to my ins. in the process of appealing. The office was quite unhelpful and told me that the Dr. is on vacation (I was like...you don't have a back-up Dr. in her place while she's out or what???) so I had to put everything on hold & wait until she get back from her vacation which is about 2 wks (ridiculous). I then thought miracle has happened since I was able to get some assistance with their billing dept lead, Jessica Nguyen (I think that's her last name). She was nice enough to fax over a one time request for insurance to rethink of their decision (didn't explain anything except asking them to rethink and pay this bill). She never gave me a "Letter of Medical Necessity" which is the one thing I've requested from her multiple times & it is the main thing that's needed by the ins. co. I then tried to call her multiple times and leaving voicemail on her office line but she never pick up or response back. Overall, I felt this office and Jessica/billing dept was unprofessional. All they have to do is response to me and tell me there's nothing they can do but yet they chosen avoidance instead. Throughout this ordeal, the Dr. office keep blaming the vendor saying that they're the one who lied to the office about having this procedure be covered by insurance co. I felt that the Dr. office were not accountable for their wrong action and I'm hoping that others will learn from my experience and never to go to this unprofessional medical office/clinic (or their affiliated offices since management is questionable) as there are many other physicians/healthcare practitioners that are better and care about their patients more. Unfortunately for my mom, she's now stuck with an unnecessary bill due to the Dr/billing dept. not doing their due-diligence. Once again, I'm hoping others will rethink before signing up/going to this office since they basically have no accountability & not professional what so ever. read more
