I've been with Vista medical group for 10 years & I absolutely love the care our Doctors provide. My kids see Dr. Maria Castillo. She always takes her time with them & is respectful & kind to our special request regarding our health choices. I've personally been going through a healing cancer journey for the last 7 years and I could not imagine a better doctor than Dr. Azar by my side. He is willing & happy to move mountains to make sure that I'm getting the right care & support. He is incredibly knowledgeable beyond just allopathic medicine. He is intuitive, & highly wise in nutrition & overall wellness. I am grateful to have Dr. Nazar on my side! read more

If I could give zero stars I would. I came here when it was vista and was happy with Dr. Maria and Azar. I have been trying to get an appointment with Optum for a week and they have never once actually picked up the phone at all. I was on hold for over a week on various occasions for more than 30 minutes each time, at different times of the day. I'm literally still on hold with them as I type this. Never would I entrust my health in such an unprofessional place who doesn't even care to pick up your phone call. I switched today because this is unacceptable; I would've asked to speak to a supervisor if they ever even picked up the phone. The good reviews I've read are all from vista and the recent Optum ones are garbage read more

Optim corona is the worst place for health care, my mom went there 2 tomes with high blood pressure and they did not treat her for it and they wouldn't let my dad inside to translate read more

My podiatrist provided service and billed Optum! It is continuing ,treatment and Optimal paid for it in the past! In May, Optum denied payment as not covered service. However, a week later during a conference call,with Optum and Health Net it was established that the service is covered and Optum's responsibility to pay. To date, 1/3/26 it has not been paid and is being turned over to a collection service. Avoid any medical group that uses Optum. It can result in ruining your credit score!​ read more

I arrived at their office at 3pm. All the workers were in the lobby inflating balloons and told me they were not taking any more patients for the day. A female worker told me they were no longer extended care as of Friday but that the changes were not made yet (that made no sense). The website still listed them as open and also as extended care. I asked what time they closed. She said 5pm but that the doctor was at lunch and would not see anyone else. It is very frustrating to have to deal with this kind of medical service specially when you are not feeling good. read more

Well....they don't answer the phone, called at 130, figured there still at lunch, called at 3pm, phone just rings...it's Monday, open till 8pm...I'll try later. Was waiting for my asthma meds to be delivered to my home...had been out of my daily inhaler for 3 days, pharmacy says"doc canceled it, till you get blood draw...nobody told me this! So now been off my daily meds for 5 days, I can't breathe!! Can't get ahold of any doc, I'll probably need to go to ER now! Such care they give.​ read more

Cant reach anyone on the phone to even make an appointment. All I get is that the line is busy or is disconnected. Please update your phone number. Not sure how you operate as a physicality if no one can call and make an appointment. read more

The drs here don't test you for anything. They will prescribe you things and not test for anything. I was asked if i, myself took a covid test. Then the dr prescribed me a z pack and some other stuff normally for Covid. I had flu like symptoms. Went to a different urgent care. Not only did they test me for Covid which I didn't have but strep as well. I almost passed out at this urgent care and they didn't care nor did they carry ice packs. This place I will never go to again. They check your breathing, ears, and inside your mouth and scoot you out the door. Go to an accelerated urgent care they will run a full exam on you. The dr u saw today told me to stop taking one of the meds this dr prescribed because it has worse side effects. (Hallucinations/dizziness/etc) which it was giving me the worst vertigo of my life! Don't come here! read more

Anthony Pinner PA is unprofessional and rude. My brother went in because he was told he needed a CT scan and in order to get a referral he needed to see his doctor. Mind you his doctor is never in so he sees Anthony Pinner PA who told my brother the first time when my brother handed him his documents from his emergency room stay. Anthony Pinner told my brother this is to much paper to go over. WTH! My brother had pancreatic infection two blood clots fluid in his lungs. ER recommended CT. Anthony Pinner sent him to endocrine who he said would put in a request for CT . Endocrine stated his pcp was supposed to. So my brother went back and Anthony Pinner PA gave him a ultrasound. If they would of scanned his medical documents in the first time they would of had his records. Nope since it was to much documents he gave them back to my brother. Calling the medical board on this PA and faculty. PLEASE DO NOT SEND YOUR LOVED ONES HERE. read more

An hour and a half a waited and was the only person here and they took someone ahead of me that came in 30 mins after then she did a telehealth appt ahead of me then to top that off took another patient ahead of me because they had an appt!!!!! NEVER AGAIN THIS PLACE IS HORRIBLE!!! The care is lacking in all respects! read more

The front desk Hispanic girl was yelling at me and my 76 year old mother to go sit when all we did was ask to talk to the doctor. The Filipina nurse was being unhelpful. So I asked to speak to a doctor god forbid someone ask to speak to a doctor. Absolutely disgusting front desk. This Hispanic girl had no respect for a senior who just fell on the ground and has a big bump on their head. Instead of being helpful and asking if we need anything I had to push to talk to a doctor. It's like humanity doesn't exist at vista urgent care how are these people allowed to be nurses ? Just disgusting. I have respect for nurses and doctors but people that are rude and gross deserve no respect. I'll be writing a letter to the higher ups. This facility needs an attitude adjustment. read more

Optum - Corona - Waiting for the doctor - Family Practice Near Me - Corona, California

Vista Medical Group in Corona is the worst office I have ever encountered, and I'm not even a patient! I called the office at 951-549-0900 to ask general questions on behalf of my sister-in-law, who had a stroke and can no longer speak. First, I spoke to Perla, in medical records, who interrupted every word I said and didn't let me speak. When I complained, she left me on hold. I hung up and tried to call back, but they saw my number and hung on my like 10 times! I finally blocked my number and they picked up! what a coincidence. I spoke to the Manager, who said we are having phone issues...yeah right. She was just as rude as Perla! awful...and she's the manager?? Please beware of this place. read more

Check in at 12:30 PM, my appointment is at 12:40 pm, got the paper work, filled them up, let us say it took me 30 minutes to fully fill out everything, time passes till I realized it is 02:30 PM, so it is been two complete hours in the clinic setting waiting to see the doctor. WHY, WHY, WHY. I ask the receptionist at 02:35 pm she said sorry we are little behind and the doctor is little behind with patients, I told here then you shouldn't schedule more appointments, it took me more than 45 days to schedule the appointment and when I come on it I waiting 2 hrs you guys should respect my time, I have things and responsibilities to do and you telling me little behind. I told here this is the first time for me here and I waiting that long, I do not want your service and I do not want to be seen by the doctor, remove me from your system and I will change the Dr with my insurance. read more

Poor customer service. It is really hard to communicate with your Dr or look for answers. You need to be really patient if you are trying to contact your Dr. The leave you hanging on the phone. They transfer you like 20 times (probably trying for you to give up). They never call you back. Bad experience. read more

Date service rendered 7/20/2021 -TIME 12:01-12:12 pm You can't always depend on the help to answer the questions or reassure you of what you and your doctor discuss. I don't care if you as a professional nurse/secretary feel assured in your responses, if the patient doesn't, then you figure out a way to best explain the answers to the questions being asked without the covert disrespect or you find someone else whose able to. Just because you're having a bad day or don't like the patient that your job requires you to attend to doesn't warrant your lack of respect. If & when the contempt is returned then you'll want to play victim and gossip false narratives. Some aren't privileged enough to know the patients entire medical history & for that Reason incorrectly assume that everyone is the same or can speak openly without consequence. Even the phlebotomist at labcorp wanted her name to report the unprofessionalism she was subjected to when calling their office to verify a lab request. It's not the establishment as a whole that's bad, it's certain individuals who bring negativity to the establishment as a whole that give it a bad name. Hopefully the employees won't follow the lead of an overly emotional female who doesn't know how to lead. It's almost as if they become vindictive & are mad with the ill patient for their messing up. read more

I first gave Dr. Azar himself 5-stars, as he is a good and decent man and doctor, and always enjoyable during my many visits there. He got me to switch to being a vegetarian too! He appears to genuinely care for his patients and is doing a great job. Yelp is bugging me to review the office staff as well, lol. My experience in that realm is hit and miss, mostly MISS. I am not sure why this is and am a bit confused by it all. I would love to say more, but will reserve that for later. UPDATE-down to 1-star: I will have to agree with a great deal of the reviews here that give this medical group 1 star, primarily due to the support staff. They are just AWFUL. Stuck up and full of themselves, uncaring, super rude, never answer their emails, put you on hold and pass you person-to-person to try to get rid of you, and screw up appointments and referrals constantly. I don't understand WHY the good doctor continues to employ these people. They are the WORST. read more

First of all I wanted to thank miss Araceli for the great exceptional customer service went over and beyond.... I was waiting in the pharmacy for a while and she made sure that I got what I needed everyone here is very helpful and caring much love they share... thank you vista medical group for hiring beautiful people like this... if anyone goes to them ask for miss Araceli and give her a high five from me Victor read more

They make many errors that will cost you time and money. For instance, the second to the last time I was there they gave me my receipt at the end that had my name right at the wrong address and phone number- belonging to another guy with my name -clearly a HIPAA violation. This also created a big mess in trying to get my prescriptions refilled. On my last visit the physician assistant (you'll typically get a younger PA, not a seasoned doctor), gave me an order for an ultrasound and put the wrong information in the check box. It wasn't till after I scheduled my ultrasound and showed up with my paperwork did the tech notice the error. I went to Vista because they are in my #Cigna "in-network" and wanted to save a few bucks - my mistake. (Speaking of Cigna- all their In-Network DRs and centers near me have the lowest customer satisfaction and yelp reviews- why is that Cigna? What's that say about Cigna's quality of care?) On the positive side, I did have two other visits that they did just fine for me- they were on target and reasonably quick about it. Hit and miss I guess. But I'll be going to Norco Urgent care next time. read more

Front desk was friendly and efficient. Waited in a HOT room for a doctor for over an hour. Doctor was not polite or caring upon arrival. Then the doctor told me my son either had a virus or a bacterial infection and he wasn't sure which but prescribed antibiotic anyway. I am only a mom doctor but I already know it's either a virus or bacteria infection. Waste of time and money. I had to go to another urgent care for a professional to help my son. read more

I highly recommend switching doctors if you haven't experienced another other then this low quality group of individuals. I came in last year for a physical & wasn't feeling completely there (Mentally & Physically). I had some concerns I wanted checked & everything was dismissed by there doctor with the worse attitude I've dealt with. I was repeatedly told I'm young & there's nothing wrong with me. Followed by I should probably stop working out. (What doctor tells someone to stop working out) I got my blood work done with labcorp. If I didn't sign up for an account to view my results I wouldn't have known that my wbc, vitamin b12, Vitamin D3, & a number of others were abnormally low. I finally switched doctors after years of being signed up with these shady individuals. Best decision I have made. I already have an appointment to go over my blood work & to see a specialist in regards to my gastric issues. I checked my records & it was Anthony Pinner at the time of my appointment. This guy needs his medical license revoked. Does not need to be a doctor & have other peoples health in his hands. His attitude is horrible & his overall carelessness with his patients is evident amongst other reviews. read more

Horrible service! All the front desk ladies do not help you! I arrived and was not greeted I was ignored, so I took a seat. A few moments later another person walked in and got greeted and helped right away. After signing in before everyone else, the next person was called, then the next person after that. WTF After waiting over 40 minutes with nothing, I finally said why have I not been helped and the past 2 people that came in after me have got helped and already left. I needed to use the restroom and I told her that, she didn't care or try to help me. Avoid this clinic at all cost! They need friendly helpful front desk personal. All 3 woman were of no help. This clinic sucks, they need to hire better front desk read more

I came in to Urgent Care just before 9:30 AM. Saw Dr. Carrington regarding a bladder infection peeing blood. I called my pharmacy over 3 hours later & they still had not received the RX from Dr. Carrington. I called the Urgent Care & got Wendy on the phone, she was very nice tried to get the RX called in. When I went to pick up the RX, there was no antibiotic.... I called the Urgent care and this time got a guy named Trinidad and explained the situation. He said that the Dr. was in a room with a patient and he would call me back. After about a half hour I still hadn't heard from him and it was 6:37 PM by then so I called him back. He was useless and rude & kept saying that I was not their only patient. He was very unprofessional and does not belong interacting with patients. What a waste of oxygen. I went back to this Urgent care and Frances tried to diffuse the situation. Not once did Dr. Carrington come to the phone, call or come out. It took over 9- hours to finally get what I needed. I cannot recommend them. read more

Whatever you do dont go the Vista urgent care in Chino Ca! No X-ray tech available, the person at the front desk was rude with no compassion whatsoever! She would hide in the back and was nowhere to be found ! We needed a wheelchair and she could care less! when your in pain it's not easy getting in and out of a car just to go to Another urgent care! read more

Close this place down! This place is horrible! I have never ever been treated so bad! I still cry because of my experience with these people. They don't care. I was so ill and they judge me and they kept me out of work for 3 months! Just so they can literally say to me in my face that they are just putting up with me because of the doctor saying it was in my head! How? Why keep me out of work then? The specialist I was referred to finally told me my diagnosis and I was literally dying. I can't believe these people at Vista Medical Group in eastvale and chino are people that are in charge of health and people. Luckily I can stand up for me and I will be taking action on these people I will not keep quiet about the discrimination and the abuse I received with these so called medical professionals and doctors. read more

As others have stated this place is ridiculous, they keep you waiting forever to be seen, 1st one in when they open the doors at 8am, being seen for a simple return to work evaluation and it's already been over 45 minutes in the front waiting room. I've been here in the past for the same thing and sat here for 3 hours. read more

I've been going to Vista Medical Group for many years but today's visit is my last. I'm actually very upset at myself for not dumping them sooner. Dr. Azar, the only doctor they have is an extremely rude, condescending, and distracted person who has an attention span of a toddler. He's impulsive, always distracted, rushed and never listens to you. When you say you need some questions answered, he starts yelling and tells you that he doesn't have time for you as he has many more patients to see. I wonder how he could do his job of diagnosing or treating anybody with these kinds of personality disorders. He either needs to retire or hire somebody competent. AVOID this doctor and this office at any cost. read more

Front and back office staff are rude! Brought my son for physical wished I had gone elsewhere!

This is the worst place to get anything done the right way they never do what they're supposed to do the people in the front are not paying somebody's not paying attention if you go in there they're going to screw something up for you no I was there today at urgent Care and they never called my prescriptions in so now I can't get hold of anybody on the phone or anything read more

Called in about setting up an appointment for either over the phone or in person, and the staff said I would only be able to do a video appointment (due to my symptoms) just for the them to charge my insurance take my copay and tell me I need to be seen in person for medications. The quality of care from this particular location is trash!!! Go somewhere else, don't waste your time & money read more

I have worked in medicine for over 30 years in a number of capacities. I have never been in an office so disorganized. Prescription refills do not happen. They never contact you regarding lab results. My husband is DM2. He had protein in his urine, his A1c is high, plus a number of other abnormalities. That was three months ago and no word. I called with bladder symptoms and was told they could get me in in two weeks. The ppl that answer the phones and make appointments are not the least bit educated. I've been denied refills, being told I need to be seen, while already having an appt on the books. There is no consistency in this practice. I made an appt for the bladder symptoms. They were doing a culture. The first one out of the cupboard was incomplete, the second one was used for the culture, BUT the EMPTY culture kit was sent to Quest. It's pathetic and also very dangerous. Not worth the trouble or medical risk. read more

The doctor who attended me was so kind and insightful. I felt safe and cared for and was attended quickly

If i can give ZERO stars I would. I made an appointment with my primary care to get my daughter her shots for school, and they said they didnt take my insurance. We've been going to Vista for a few years and now you dont take my insurance. Why did your office make me an appointment? We will NO longer be going to Vista. BYE! read more

Unfortunately I am so disappointed with VISTA right now The fact that I can't even get anyone to answer or even return my calls just to make an appointment is unbelievable And today they kept switching me over and over and then for someone to answer only to hang up on me needless to say I'm still trying to get through I love going to Vista and I come from sanbernadino but today and for the last week has been nothing but trouble trying to get through I just need an appointment Someone Anyone should be able to just give me an appointment And no purpose of having a website that asks what days and times would you like if nobody is reading them I hate writing a bad review on my doctors office but they need to know what is going on and agree this is not acceptable read more

I was turned away this morning from urgent care and told to just let my antibiotics kick in. Didn't even bother to let me see the doctor. I'm on day 3 of antibiotics and I'm getting worse and I'm in pain. I understand antibiotics take time, but a consultation with possibly prescribing additional medication to help me be more comfortable until they do kick in would have been nice. The only reason I came here was because they open an hour earlier than other urgent cares and I was in sever pain and discomfort. My otc cold meds arent doing enough to help me. I've seen other reviews along the same line of being denied. They did offer me a phone visit as I was crying and leaving which I did say yes to, but later denied. I already told you what was going on and all they had to say was let them kick in, essentially suck it up. What makes you think I'm now going to be comfortable telling you AGAIN what's wrong and expect a different answer from you. What a joke. I ended up going elsewhere and was listened to and prescribed more meds and different antibiotics because of my severity. I think the lesson here is to listen to your patients, they know when something isn't right with their body read more

Had an outstanding experience at this urgent care with Dr. Carrington. Exceptional bedside manners, incredibly helpful, and resourceful. Dr. Carrington attentively listened to my concerns and provided valuable recommendations. I would certainly return - he's an excellent doctor! The receptionists were also great - everyone was so polite and respectful. Highly recommend this urgent care; Dr. Carrington genuinely cares about his patients! read more

They should probably reconsider the sign on their wall that says "your referrals are the best compliments", considering they obviously offer zero customer service training to their employees. Got hurt at work. My company sends me to Vista with my Worker's Comp insurance company name (it's a large carrier) and claim #. I call on my way, they say "as long as you have your claim #, that's all we need!" I get there and meet Ms. "I didn't get my lunch break" and she was NOT going to budge. Apparently because the insurance company had not faxed (who faxes anymore??) them authorization, they wouldn't see me. I asked her to call them, she said "you can call them". I asked her again to assist me, she refused. We walked out. What a joke. Went to another local UC and they helped me immediately with the same info I was offering to give her. Obviously they got what they needed to get paid and Vista isn't interested in that, or making customers happy. I live nearby. I will NEVER go to Vista again for any UC needs. Horrible. read more

On October 22,2023, I took my husband to Vista Urgent Care in Corona. My husband and I cannot begin to express our satisfaction with the staff, from the front desk, Ms Grace, to the Medical Assistant/X-Ray Tech, Ms Millie Castillo and the PA, Ms Maggie Carpio. As soon as we entered the clinic, we felt comfortable and felt the positive vibes. Each and every one of them was courteous, professional and made our visit as comfortable as they possibly could. Our wait time in waiting room and the exam room was quick. PA Maggie Carpio took the time to listen and to answer all our questions and she made us feel like we were the only patient there. She didn't rush through things. We both are very satisfied with the care and attention that we have received from her. Thank you so much, Dr. Carpio for caring and for being so compassionate . And to Ms Millie Castillo, she is very friendly and she presented herself in a positive, professional manner. Thank you so much for the caring and friendly can do attitude and smiles. Overall, the PA and staff provided excellent professional and courteous care. We highly recommend a visit to Vista Medical Group Urgent Care located in 2071 Compton Ave., Corona, CA. read more

Not sure if I return back. dr was very nice but it always takes forever. My son had a 104 fever and waited 20 minutes before we saw a Dr.

I checked into the office at 10:55am and was called to be seen at 12:15pm. Yes that it a whole 1 hour and 20 minute wait. I asked why so long of a wait and they said they were busy. I've been to other medical offices like this for the same thing and when the waiting rooms were full, I was seen within 20 to 30 mins of check in. I chose this place because I was referred by someone. The office itself is nice and clean in appearance with a pleasant staff, and a large screen tv in the waiting room for your eyeball pleasure. Ask about the free tote bag with your Yelp check in. read more
