I had a bad experience this morning that gave me a bad taste in my mouth concerning this business…read more(Advance Oncology Center) in West Covina, Ca. As we arrived to take my 91 yr old mother to her appointment, having 16 daily total appointments, apparently one of the male workers explained that we have been late everyday for the past week since we started taking my mother and they been accommodating us, which is untrue and unfounded. They have not been accommodating us, in fact we are the ones waiting to be called when arriving early. I explained we haven't been late as the appointment was at 10:45am and not 10:00am as he stated. The worker stated he wouldn't be able to see my mother today since we were late and had other patients. After review of the print out of all 16 appointments, today appointment was in fact at 10:00am as the worker said but every other appointment was at 10:45am. Now sharing rides among 3 of my siblings, we have been sharing, taking my mother to her appointments. Some coming from different areas Covina, Glendora, and Pasadena not knowing traffic and to be late, didn't feel we should have been treated and scolded when we been there on time. I felt if we need to wait, when we're early for appointments, sometimes over 30 minutes, a few minutes shouldn't be an issue. I sure hope they have the same schedule as given. Maybe practice on better service skills and review the schedule times, before assuming we are late numerous of times.

They told me on the phone of the up front co pay to pre order the injection so I paid it and made the appointment thinking It was going to be quick. When you have cancer and are so sick the last thing you want to do is sit in a waiting room with other sick people.theres no compassion here.

After a year and a half of trying to give them a chance, I've transferred my care elsewhere, and the experience where I'm at has been much much better. Please avoid this office if you are able!

Part 1 Sit back, this is going to be a long one…read more I was diagnosed with breast cancer in October of 2025. This was surprising and upsetting. It was more important to me to focus on the cure than the diagnosis. It turns out there are so many appointments and so many hoops you need to jump through when dealing with cancer. I made my initial appointment with the oncology institute as soon as my authorization was issued. My first appointment was on 11/21/2025. On the first visit there wasn't much to be done except meet the doctor, get bloodwork paperwork and make another appointment. The next appointment I set was for December 26, 2025. I asked specifically if the dr was working that day because I thought that it was odd that the dr would be there on a Friday, the day after Christmas. I was assured he would be so I put it in my calendar. (An afterthought on this visit. As I walked out of the room, I asked if I could use the restroom. I was told yes, there was a restroom outside. That seemed so logical to not let me use the restroom 10 feet down the hall {the same one they let my husband use prior to going into the room} when they could have me go to the front desk, ask for a key, go outside to the restroom used by all of the businesses and then return the key. Just plain rude, but quite foreshadowing of the following encounters I would experience there.) We left the appointment and went straight to get my bloodwork done. On December 26, 2025 (I unfortunately came down with that flu bug that was going around, but I had an appointment) my husband and I went in for my scheduled appointment. Upon arrival to the facility, I was told that the dr was not in and I would need to reschedule. I was beyond annoyed, First, I had asked specifically when making the appointment that the dr was going to be in that day, Second, I felt miserable but kept my appointment because I had one. I would have preferred to stay home and in bed. I asked why I got no call to let me know the appointment had been cancelled. I was told that they didn't know and they were not the person who made the calls. They seemed neither apologetic nor sympathetic. I suppose I should have been appreciative of the fact that they were willing to schedule another appointment for me. The rescheduled appointment was for January 16, 2026. We arrived on January 16th for my appointment. Luckily, the dr was there and I was going to be seen. I gave them my $50 copay and waited to be called back. When being called back to the exam room, my vitals were taken and I was asked if I had any concerns. I told the young lady that I had been having dizzy spells and that was concerning me. She noted it on my chart (I think). When the dr came into the exam room, he let me know that my bloodwork all looked good with the exception of my kidneys. I told him those numbers were probably still off since I donated a kidney in August (this was discussed at my last appointment with him). He asked if I knew the person (still no like the last time we discussed it) and if it hurt when it was done. I let him know I had been under anesthesia so I didn't feel a thing. That was the extent of our conversation for the most part with him telling me to make a return appointment three weeks after my double mastectomy. He didn't mention my dizziness, the visit seemed well worth my $50 and time spent. I could not of anything better to do with my time or money or stress regarding my cancer. I went to the front to schedule my next visit. I let them know I needed it 3 weeks after my surgery. I pulled out my calendar so I could record the date and time. We looked at the calendar to find a date 3 weeks after my February 5th surgery. I was given the date and time, wrote it down and was also given a print out for the appointment. When I went home, as I was putting the print out in my notebook, I noticed that the date and time were incorrect. The appointment reflected on the paper was a week after the surgery. I immediately called the office to let them know they recorded it incorrectly. After attempting to explain the situation with the person who had answered the phone, they responded with the notion that I needed to reschedule my appointment. No, I just needed them to give me the correct appointment that I was given in the office when I was there. I guess this incompetence was just another perk of paying $50 (those who have to pay more probably are thinking I am lucky to only have to pay that amount, I agree but my insurance pays a lot for nothing there.) We scheduled my appointment for March 12, 2026. Apparently, these reviews are limited to a certain number of characters. Things did not get better on my return...I was told by their rude staff I was no longer a patient because of insurance. The story is longer and has been a horrible experience. Based on the other reviews, I am not alone in my feelings of this place. More stress for a cancer diagnosis.

My mother's been in pain and constantly telling him, but it doesn't seem like he would want to do anything to help her, just showing no sign of effort. Saying something down the line like there's no need for you to do chemo anymore since nothing is working. Hope this message reaches out to future cancer patients because it would suck if you have to deal with someone like Hank on a Thursday afternoon. I wish for everyone to receive good health and good service from doctors because that's where our tax dollars are going, not to some grumpy old man that can't do his job right and gives up in a heartbeat.
