I have been going there for six months, and it's been 100% AWFUL in every aspect. You can't get through to the actual office to speak to anyone or make an appointment. You get sent to some other country to make appointments or getting a message to your provider, which don't get to the provider. I had a very important message to let my provider know that I was going to wait on my bone marrow biopsy which my provider told me that she didn't get it. As well, when I did go to my follow-up appt, my provider ordered the wrong bloodwork, and the office sent me a message to do the bloodwork before my appt. which I did, and it was the wrong bloodwork and I didn't get any answers as far as what my issue was. As well, the billing department is terrible. For 5 months I called repeatably trying to get a billing statement with no success! As well, I had to call many times asking them to subtract off the co-pays I paid. They told me that would be sent to the statement dept., which there was no such thing in the end. You get someone from overseas that barely speak English and they say the same thing, that they will look into it for you and call you back and they don't. I was finally able to get transferred to a supervisor that promised to email me a statement and mail me one as well. I never got either one. I got a copy of my ledger a month later with no return address to send the bill. I had to send her three more messages and threaten to get an attorney and, a month later I got a letter stating that they have been changing the billing process and I was sent another copy of my ledger, not a billing statement. But, on the letter they typed out the billing address to send my payment. This office runs absolutely terrible in every aspect! And anyone that has cancer or trying to find out if you have cancer this place will cause you an unbelievable amount of stress when that is the last thing you need. I now have to go to another Oncologist to get the correct bloodwork ordered so I can get some answers, after waiting for 4 months only to have the wrong bloodwork ordered and no answers. I will continue to file complaints with other organizations that will look into the way this facility is operating, AWFUL! Betsy C read more

I want to thank Dr. Kandahari at the Oncology Institute in Temecula for the professional, thorough and kind attention. Having an oncologist who is educated and caring in this field makes this medical challenge a bit easier. And thank you to Maricella and Dr.Kandahari's medical assistant for their kindness and caring attitude. read more

This "doctor" Osagie Bello, made my friend's mom's cancer much worse & she just recently passed. I wouldn't recommend them in the slightest - they shouldn't be able to practice. DO NOT GO TO THIS DOCTOR. PLEASE. read more

Not only is Dr. Baseri very unprofessional but he makes you feel bad about not knowing your family's medical history. When I contacted the office for clarification about getting bloodwork done, they never had the doctor or PA respond to me and, when I followed up, they told me to go to the emergency room... It wasn't an emergency! I just wanted an answer! Then I told them I was not feeling good about how they were not responsive and not helping me so I wanted to see a different doctor and they said, "Of course...have a good rest of your day." Then they canceled my appointment. They didn't seem to actually care if I was their patient or not. read more

I waited for one month to have an iron infusion when I found out from the answering service they could not get medication. The service told me to go to another medical clinic. I never heard from any medical personnel. I had to go to emergency hospital. read more

Seriously the worst doctor's experience ever. They called 3 times and canceled my appointment and said the doctor was too busy and the last time they say they called and left a message on my voicemail and they didn't. This place is horrible and incredibly unprofessional. Choose another doctor. read more

Went for a consult and he recommended a treatment plan that was not consistent with NCCN guidelines. Saw a surgical oncologist who reviewed the guidelines with me and explained why I needed surgery. When I saw Dr. Baseri again and told him this he was very condescending and stated "why? They're not going to find anything". One of the reasons it was recommended to have surgery was to get full staging, and turns out I am stage 3 and need chemo, whereas Dr. Baseri had me at stage 1. If I had stayed with his plan my life expectancies would have been much shorter. read more

do not i repeat do not go to this facility or any that has a dr osagie bello. this guy is a total scam. his office staff is inept. hes down right snarky and tried to immediately put you in fear that that you need chemotherapy before he has a chance to thoroughly exam you. hes is an oncologist but never ever examined my breast or anything. just talks a lot of shiit. i filed a grievance against him. im yet to receive my copy. money over patient care. be careful. i' think he's from nigeria. i have to call it what it is. i can't say he's asian if he's not. no racism here just facts. read more

The whole corporation is a fraud. The company's corporate office is located in Cerritos, California. a.k.a somewhere in the Philippines. You get a brief consultation with a Doctor?! In my case I was unlucky enough to get Dr. Answer Shaikh. Who is rude, obnoxious and obviously a hatemonger. He tells you what's wrong and what treatment you need and poof. You're on your way to the most undescribable dysfunctional oncology - hematology medical practice. I could go on but I'm not helping you nor myself. If You want a competent, caring and compassionate Cancer center. Then this is not the place. Good luck and God bless on your healing journey. read more

I would never recommend this place nor Dr. Baseri. He is very unprofessional and does not spend anytime to get to know you. I guess this is what you get when you get a Dr. that got his medical education in the West Indies and not in the United States. Not only did I fill out the new patient paperwork when I received it but when I got there 2 other people asked me the same questions from the paperwork. The nurse practitioner came in and asked questions then proceeded to tell me she had to get his attention so he would actually come in the room or it could be a little bit. He came in maybe 10 minutes at the most and all he talked about is cancer. I was there to get tested for a genetic blood disorder not cancer. He proceeded to tell me about a patient he has that is in his 30's and has colon cancer and I need to get screened for it. Line of questioning was off topic and he proceeded to give me a prescription for lab work with about 15 different labs that had nothing to do with why I was there or what I needed to be tested for. After debate he reduced the labs and I left with the order I needed. I'm overall disappointed and dissatisfied with the visit. read more

Hit or miss. Sometimes I have very good experiences and sometimes I wait for 2 hrs after my appointment or the OC infiltrates and the nurse refuses to change it, they are very good at collecting the copay's. Doctors are very good though. And so is some of the front desk staff. read more

My suggestion - Stay away from this office at all costs! After a diagnosis of breast cancer, I was referred to The Oncology Institute for treatment. my appointment was made with Dr. John Schwerkoske for 10 am. I arrived at 9:30 to do paperwork. At 11:00, I was taken into a room, and vitals were taken. At 11:35, the doctor walked in, didn't introduce himself, stared down at his laptop, and said "Why are you here today?" Terrible first impression, but since I wouldn't need to see him again for another 6 weeks, I brushed it off as a bad day. My second appointment was just to get a referral to a radiation oncologist. I walked in early for my appointment to an overly full waiting room, listening to patient after patient ask the receptionist when they would be seen. Each of them saying they had been waiting over an hour already. At my 45 minute mark, I asked the receptionist if I could just get my referral, so I could leave. She got up, asked the doctor (in my line of sight), and then he looked at me, and waved me back. He walked me into a copy/coffee room, then asked a nurse to come in and take my vitals. I told him no way, and that I just need my referral so that I can get my radiation treatment started. He said well, how about you come back tomorrow afternoon, and you won't have to wait as long. Like, what?!? Just give me my paperwork! The receptionist printed my referral, and I left. I immediately called my PCP to ask for a new oncologist. Several hours later, Dr. Schwerkoske called my cell phone, and said he reviewed my file, and would like to set up another appointment to go over my treatment plan. I told him that I would not sit in his waiting room any more, and said I would happily do a tele-health appointment. He said that would be fine, and we set up an appointment. Guess who never called? Yep, you are correct. A receptionist called an hour after my appointment time and said "I was just checking to see if the doctor called you?" The next day, at 8:30 pm, the doctor called, and flat out lied to me telling me he called me "several times." I let him know that I was seeing another caregiver, and that he needed to reevaluate his choice of profession, because he was terrible at taking care of cancer patients. Again, stay away from this office at all costs. They will leave you frustrated, and not cared for. read more
