    Waiting are and self check-in kiosks.
    Tina P.

    Quest is a great alternative to getting your labs done if your doctors are located far away. The phlebotomists here are very nice. It is a big laboratory now, however I was frustrated with the new check-in-system, make sure you have your driver's license and insurance on hand as you will need to scan each one of them and time runs out during check-in if you have to get it from your purse. It is also hard to get appointment times, if you have an emergency lab that needs to be done within a few days and before a specific time in the morning, it is very difficult to schedule an appointment.

    Needed lab work done and my Dr wrote an order for Quest. I got home and looked on their website for the next available appointment. It was 2 weeks out.....what the heck???!! 2 weeks? OK, so 2 weeks go by and it's time for my appointment. This location is in the strip mall on Azusa - in the same plaza as Bank of America. I arrive and check in using the screens in the lobby. There was no attendant there, just screens for self check in and other patients waiting to be called. The technician called my name and I went with him to the room where he would attempt to get a few tubes of blood. First poke - he misses the vein. Second poke, he misses again and them attempts to move the needle while its still in me - if you haven't had that done, it freaked hurts a lot. When I had Kaiser, they would get it on the first try and they would see me the same day. What kinda circus did my Dr send me to???? Never again. This place is a joke.

    Update , 4 hrs already still waiting !!!! I wish i could make zero star to this worst Lab ever !! I'm honestly baffled by how complicated this lab made something as simple as dropping off a stool sample. My son needed a test, so we were told we had to make an appointment just to drop it off -- because they need time to "make a label." I'm not sure how long printing a label is supposed to take, but I can't imagine it's more than a minute. The bigger issue is, how am I supposed to guarantee exactly when my son will poop? even a day before. It's not like I can schedule his bowels. We did our best -- rushed to the lab as soon as we had the sample -- only to be told we were more than 10 minutes late and our appointment was cancelled. We were told to wait as a walk-in instead. I've now been waiting here for over 3.5 hours just to hand over a stool sample. The process is beyond frustrating and unnecessarily difficult for parents already stressed about their child's health. There's got to be a better way to handle something this basic. Absolutely ridiculous experience.

    Dont ever go as a walk in unless you plan on waiting half a day to be seen. Even with an appointment this facility is slow.

    Even with an appointment, checked in a timely manner, don't expect to be called in for like 20-30 minutes.

    I had an extremely disappointing experience at this location. Unfortunately, the customer service…read morewas unacceptable, and the laboratory area appeared unclean, which raised serious concerns about the facility's standards. Additionally, the employee (Asian Female) assisting us at the Hacienda Heights location on Colima was rude, dismissive, and unprofessional throughout the interaction. To the point where she closed the door in my face and said "Come Back tomorrow". Mind you we got arrived 15 minutes before they closed. As a customer, I expect to be treated with courtesy and respect, regardless of the circumstances. It is concerning that someone displaying such poor customer service skills would be placed in a position that requires direct interaction with the public. I sincerely hope management takes this feedback seriously, addresses the cleanliness concerns, and provides additional customer service training to ensure future customers receive the level of professionalism and respect they deserve. HORRIBLE PLACE!!!!

    There is only one staff doing all the blood draw, paperwork, everything. Staff is Chinese with very…read morelimited English. The wait was an hour just for blood draw, eitha. Total of maybe only 4-5 people ahead of me. There is a sign in sheet, but it's completely useless as the staff never calls name from that list order. Instead you have to remember who was before and after you and keep an eye out when it's "your turn". Compared to Quest this lab felt like it has technology 20 years behind it.

    A few weeks ago, I started having some health concerns and was worried about how long it would take…read moreto get everything sorted out. A friend recommended this clinic, and I'm glad I listened. From check-in to checkout, the entire process was smooth. The staff were kind, attentive, and made me feel comfortable right away. I expected the referral process to take days, but they handled it quickly and kept me updated. When I needed medication, the prescription was sent out without delay. It's rare to find a clinic where everyone genuinely seems to care about helping patients. Their efficiency, professionalism, and friendly attitude turned what could have been a stressful situation into a very positive experience. I would definitely return and recommend them to family and friends.

    Oh, please. If there's a zero star, the NP deserve a zero star. I was calling them today like 3…read moretimes regarding my mom's lab results. They keep saying: "oh, we're busy right now, we'll calling u back." It never happens. All lies. Zero calls back. Worst one, the NP was yelled and didn't even want to listen to the complain, and hung up. Waow! What a service! Super epic. They called, inform about "something" that wasn't a clear instruction, and wanted us to check with a neuro specialist. How to communicate with the next doctor, if the instruction I received wasn't clear? If u inform something to someone, and someone communicate it to someone else, and it became unclear what do you want, cannot give response back, get the hell out pls. Do it yourself. Don't care what u want anymore. When I asked, "nicely"... their response was: oh, we're VERY busy right now, we WILL call you back. PRETT!! "Liar!" And the NP was saying: "don't u understand that we're VERY BUSY!!" "You need to listen to me!" (When she's the one NOT listening!) (After I called 3x and waited for them to call back like almost 8 hours???) Don't u think I AM NOT BUSY MA'AM? I was "too busy" waiting for your response, just to ask, what do u want from the neuro? From the kidney doctor? What the hell u want? Explain it nicely, not so complicated ma'am "busy-in-the-world." I'm sure the doctor is a nice person, but NOT the ma'am NP! She's a fucking bullshit!!! Not a profesional at all. They tend to hanging up their phone OR just blocked u into a busy line, so when u called them, NOONE (like literally noone) will pickup the phone OR listen to your voicemails. Their phone is broken, just like their heart is broken. Probably, just come to their busy office, and see how "busy" they are blocking people's phones call to make a very QUIET room. Wow!! Applause to their profesionalism. That's how they got their profesional degree. Just blocking people's phone, and do prescription till their patient's kidney is broken.
