My father received treatment here for over a year. He was treated with dignity and respect despite…read morehis infirm condition (RAEB at age 93). The Oncology Institute accommodated his wheelchair and were always clear on what the course of treatment was. It was simple to schedule and re-schedule appointments. At one point an oral chemo medication was prescribed and they were able to take the copay for the pills in the office. Dr. Manuel Zavallos was able to explain what was happening to my dad, what the treatment should be and most importantly WHY each course of action was being taken. Katya and other caring clinicians administered injections and blood draws with compassion and prioritized uplifting my dad's spirits. There were a few times my dad needed blood transfusions at the ER and the Oncology Institute had complex paperwork ready for pickup for us on our way to the hospital. While my father's passing was inevitable with this dreaded disease he was clear with me that the Oncology Institute extended his life by the treatments as well as the way he was handled as a patient. They made the 93rd and final year of his life one of comfort in the knowledge his care was in great hands.

I am writing to formally express my concerns regarding the treatment I received during my recent…read moreoncology appointment with Dr. Sachdev on 11-27-2024. I left the appointment feeling dismissed, disrespected, and uncertain about the level of care I was receiving. I would like to detail the specific issues that led to my dissatisfaction and loss of confidence in Dr. Sachdev's ability to provide compassionate and competent care. 1. Lack of Compassion and Dismissive Attitude I felt that my diagnosis of breast cancer was treated as a minor or insignificant issue. While I understand that Dr. Sachdev deals with cancer cases daily, her bedside manner lacked the empathy and compassion I expected during such a challenging and emotional time. For example, when I expressed my fear about incomplete imaging and the possibility of undetected cancer, her responses did not provide reassurance or understanding. 2. Miscommunication and Gaslighting During our conversation, I expressed concern that only one specific area of my left breast had been imaged via ultrasound. Dr. Sachdev insisted that the entire breast was imaged, but later that evening, the nurse practitioner confirmed that only the specific spot where the tumor is located was examined. This inconsistency left me feeling unheard and invalidated. 3. Inadequate Breast Exam Dr. Sachdev's breast exam did not inspire confidence. She was unable to locate the lump in my left breast until I pointed it out, which raised concerns about her ability to detect abnormalities during the exam. This made me question the accuracy of her assessment of my right breast and whether any potential issues could have been overlooked. 4. Dismissiveness of Claustrophobia and MRI Challenges I was unable to complete my breast MRI due to severe claustrophobia, despite making two attempts. When I brought this up, Dr. Sachdev dismissed my concerns and claimed she had never heard of patients being sedated for MRIs. This contradicts the information provided by the breast center's pamphlet and imaging center staff, who stated that approximately 10% of claustrophobic patients require sedation. The nurse practitioner later confirmed that referrals for sedation have been made in the past, but this option was not considered during my appointment. 5. Lack of Comprehensive Imaging Given that my cancer was not detected through mammograms but was identified only after I felt a lump and requested an ultrasound and biopsy, I am deeply concerned that I have not received sufficient imaging to ensure that cancer is not present in other areas, including my right breast or lymph nodes. When I voiced this concern, Dr. Sachdev's assurance that "cancer cannot jump from the left breast to the right breast" felt dismissive rather than thorough. Steps I Have Taken Due to these experiences, I have requested my primary care physician to refer me to another oncology center. However, I feel it is important to address these issues to ensure no other patients feel dismissed, invalidated, or inadequately cared for.

She really helped to expedite the process so I could begin receiving treatment in a more timely manner. She even called me to let me know the positive results of my MRI as soon as they were available to her, which is important during these trying times. Thank you so much for all your time, effort, and compassion.

Terrible clinic -- avoid if you care about your loved ones…read more Our experience here during a cancer crisis was beyond frustrating. Dr. Kim, the oncologist, showed zero compassion -- he rolled his eyes when we told him this was our first referral after the diagnosis and offered no helpful information beyond saying surgery was urgent. He claimed he submitted a referral, but a week later we learned it hadn't been sent. No apology -- just a late submission to a surgeon who doesn't even accept new patients. We found a qualified surgeon ourselves and requested a new referral, only to be stonewalled by the authorizations department with excuses like "it'll take 7 days," blaming insurance (which confirmed approvals take minutes). No call back from the doctor. Phones go unanswered. Office feels chaotic and unprofessional. In a time when every day matters, they cost us nearly two weeks. Stay away from this clinic -- especially if time, care, and communication matter.

I never wanted to write this. But as someone who has sworn an oath in my federal role and is bound…read moreby strict standards of compliance and integrity, I have a legal and moral obligation to speak up. The Oncology Institute (TOI) failed my family and that's putting it mildly. A suspicious mass identified earlier this year was met with same day canceled appointments, delayed referrals, and no follow ups.. I not only became a full time caregiver for my loved one, I was now forced to take over TOI's administrative responsibilities: making calls, chasing authorizations, tracking down labs, coordinating between facilities. That is not the job of a family member. That's the clinic's job, and they failed. Because of this negligence, the cancer has spread and terminal. The fallout wasn't just emotional. I've lost income and have had to decline federal job assignments to manage the mess they created. While TOI hides behind California's malpractice caps and legal protections, this is no longer just a state issue. The failures here rise to a level that demands federal oversight. Formal complaints will be filed. I refuse to stay silent while others risk going through the same. I will pursue every legal remedy available to ensure this organization is held financially and ethically accountable for the harm it caused.
