There was NEVER a time that I didn't feel cared for and important. And I LOVE that EVERYTHING I need to do to fight this disease is ALL IN ONE PLACE! Makes it easier and convenient for the patients. Livia was my first contact and she set the precedent and no one has disappointed or fallen short. My medical oncologist (Dr. Chaudhary) and radiation oncologist (Dr. Gorty) are wonderful and patient doctors taking the time to explain everything to you. My Chemo nurse are AMAZING!! It is truly a work of heart for them . I would definitely recommend this group of oncologist should you ever find yourself or a loved one in need of help to fight this awful disease. Be well and God Bless

I took my mom to see Dr. Latif for her second visit, and unfortunately, I left very unhappy with…read moreour experience. My mom and I both had several questions and concerns, but I did not feel that they were addressed with much compassion or explanation. I was especially concerned about the bone marrow procedure because of my mom's age and how fragile her bones are, but the procedure and what we could expect were not really explained to us in a way that helped ease my concerns. My mom also mentioned that she had recently started experiencing pain throughout her body. Instead of asking more questions about this new symptom, Dr. Latif initially said that she was already on pain medication and that it wouldn't make a difference. I had to explain that this was a new issue and that my mom wanted to know what she could safely take for the pain. He initially suggested Motrin. However, when my mom was hospitalized, another physician had advised me not to let her take Motrin for an extended period because of concerns about bleeding and her low hemoglobin. After I brought this up, Dr. Latif then advised her to try Tylenol first and Motrin if that did not help. What bothered me most was that I did not feel there was enough follow-up when my mom described what she was experiencing. I wanted her concerns to be listened to, questions to be asked, and guidance to be given--especially considering her age and medical situation. Instead, I left feeling as though our concerns had not really been heard. I was also disappointed that the office did not have all of my mom's lab results available before our appointment and asked us whether she had completed the labs. We travel a significant distance for these appointments. I feel the office should verify that the necessary results have been received before the patient arrives, particularly when those results are important to the visit. Had we not been able to provide the information, we could have made the long trip unnecessarily. Overall, I am very unhappy with my experience with both the office and physician. We came to the appointment looking for medical guidance, explanations, and reassurance. Unfortunately, I left feeling that my mom's concerns were not fully listened to or addressed.

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.

She also went out of her way to get things to me and work around my schedule. If you ever have to have thyroid cancer, see Dr. Rao and Carol. They'll treat you right!

I've been biting my tongue about my experience with the office staff for quite some time just…read morebecause the doctor I was seeing was somewhat helpful with my diagnosis. However, today was my absolute last straw. A large number of the office staff here are unknowledgeable, unprofessional and immature. 1. I've called on several occasions asking questions, and the person on the phone constantly puts me on hold to ask someone else, then returns back to the phone with some regurgitated answer. I've also received answers/responses over the phone from one staff member, and then receive a totally different answer/response in person at the office. 2. At one point, I called and asked about submitting a continuity of care form, and the girl had me slowly enunciate "continuity" over the phone and spell it out for her so she could ask someone else about it (what it is, what to do with it, etc). From that interaction alone, I felt less than confident with the office staff handling my questions, forms, file, etc. 3. I received call that my continuity of care form (that was filled out, signed and submitted by this office and approved with an authorization code by insurance almost 2 months ago) was not being recognized and that my final appointment (mind you I'm in the middle of treatment and do not have another doctor to take over my treatment yet) cannot be fulfilled. I asked the staff member about the continuity of care form, and she said "We're not submitting those for anybody." Completely dumbfounded, I explained that my form was already submitted from the office and I have approval for this last visit before I see a new doctor (because I'm in the middle of blood tests, ultrasounds, and prescriptions). I received zero empathy from the staff members regarding my concerns of why the form is suddenly not being recognized. She was wholly unprofessional with her responses. My overall experience was subpar here, at best. Staff can truly make or break your experience, and in this case, completely broke all of my interactions with this office. The only positive comment I can confidently leave about this office is that the chairs in the waiting room are comfortable.

The office is clean, and accessible, and the doctors have provided all the necessary care and attention needed to manage our loved one's ongoing condition. The office staff does seem to change out every year or two which does affect responsiveness and familiarity. The only real issue we've experienced is having the office number go out of service, or changed to a new phone number without notice several times over the years. I would give H.O.S. an average star rating of 3.5 stars. The current office number as of 07/2026 is (626)508-0330. You can also call Dr Austin Ma's Healthcare group at (800)385-7795 for scheduling support.

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.
