    After more than 7 months waiting to be seen, I was only given a tele-health appointment with Dr…read more Virk. On the day of visit, a nurse calls me on the doctor's behalf to handle my care, stating that the doctor is "out." The nurse sent me to complete labs at Quest Diagnostics. After that, I simply received a short voicemail saying that they will follow up in 3 months, but never did. I had much better care near SoCal. Glad I took steps of my own to improve my health. I feel bad for people on Medi-Cal because Sierra Hematology is their only option.

She took my health seriously. The wait times were never very long (I saw a review that suggested they were.) She strikes me as quite intelligent. She's not afraid to look things up in front of me, and she does it very quickly. Some people just pretend to know everything. They don't. People that will look things up, like side effects from the drugs you're taking, are the doctors you want to see. Everyone I interacted with was kind and competent. We never figured out what is causing my high white blood cell count. I ended up having to leave because I had to change PCPs, and that messes my insurance up for going to Sierra Hematology and Oncology. I think the worst case scenarios have been tested for, at least. I would recommend them to everyone but my enemies.

    I had high hopes for this medical office, and specifically in working with Dr. Kellen Na. She is a…read morepretty good listener and clinician, however, she upcoded my husband and charged him for an issue that's been on his medical history for 30+ years and claimed that it is separate because he brought it up. That's the whole point of a physical, to bring up and discuss ONGOING and LONGSTANDING medical conditions, is it not? So that eroded our trust in her. As for myself, she was ok, but not very opened to other than conventional medical treatments and more or less minimized the efficacy of using functional and more holistic medical treatment modules and modalities as well as supplements even though there's plenty of medical literature showing that natural remedies are not inferior to synthetic lab-formulated treatments for many conditions and in many cases, the more natural treatments yield as good if not better results with much fewer side effects. Dr. Na also quoted sources like American Cancer Society (it's a hugely questionable "non-profit" whose CEO makes over $1M a year and also they've been accused of overly pushing statins etc. https://blog.charitywatch.org/1-million-charity-compensation-packages-2024-update and https://www.quora.com/Is-the-American-Cancer-Society-a-scam Also she had a hard time performing a pap on me, and thankfully they use a plastic instrument now instead of the metal one, or else I would probably have been screaming. She did get the speciment she needed, but it was not a pleasant or smooth experience. So unfortunately, I don't plan to be under Dr. Na's care anymore.

The medical assistant promptly returned my call, and all vital signs were taken appropriately. I had a quick and efficient visit to the clinic, resulting in a diagnosis and prescribed medication. The experience was great, from the front office to the back office team! Love Dr. Lao, but as she was out the Express Clinic Team were great!

    I am not clear why the same business has two Yelp profiles so I'm posting again: A family member of…read moremine was diagnosed with cancer, and while researching treatment options, I came across Infuze MD. After a brief call with an employee named Paolo, who spoke positively about the clinic, I shared the information with my relative. In hindsight, I realize that in my desperation, I may have overlooked warning signs. At the time, I did not realize Paolo is not a medical professional, even though he was the first person discussing treatment options. The clinic is owned and operated by Dr. Nilda Agnes Abellera, who is board-certified in PEDIATRICS but whose clinic advertises integrative medicine. My relative traveled from out of state to begin what was described as an "intensive" 20-day cancer program. According to her account, the first three days did not feel intensive. She reported that infusion rates appeared slowed, staff could not explain the scientific basis for some treatments, and the doctor missed a planned medication review. She also observed what she believed was dried blood on a chair and described an IV bag fully draining while the needle was in place, which worried her. On October 9, 2025, she said her care was terminated immediately after raising concerns, without timely written notice, referrals, or arrangements to ensure access to medical care until she could establish care elsewhere. Referrals were only provided after I contacted the clinic. This abrupt termination caused a delay of over a month in her treatment and worsened her PTSD symptoms. She also tried to obtain her medical records multiple ways. On October 10, she requested them in person but was denied. She also submitted a written request and used the clinic's online inquiry form. As of this writing--52 days later--she has not received her complete records. When I called the clinic, Paolo was tense and dismissive, and I could not speak directly with Dr. Abellera. Given the situation, I became concerned about whether proper procedures were followed and intended to file a complaint with the Medical Board of California. Additional observations and concerns (personal experience): Family-run structure: The clinic is owned by Dr. Abellera. Paolo appears to manage many aspects, and another family member may also work there. This raised questions about oversight and role clarity. Online reviews: Of 32 Google reviews, 5 were five-star without details. Only one mentioned "cancer," making it hard to evaluate patient experiences compared with other clinics with hundreds of detailed reviews. Difficulty communicating with the physician: My relative and I tried to speak directly with Dr. Abellera; she did not speak with me, and my relative felt the doctor was unwilling to address her concerns. This lack of communication was alarming given her serious diagnosis. Cost vs. expectations: The program cost approximately $1,800 per day. Based on my relative's experience, the services did not match the program description. Others may feel differently, but this was our impression. Social media promotion: Paolo participates in Facebook groups promoting the clinic without identifying himself as an employee, which seemed misleading. I have included a screenshot for reference. In more than a decade in healthcare, I have never witnessed a more concerning divergence from a physician's duty to do no harm: terminating care without notice, effectively leaving my relative without immediate, comparable care options while facing life-threatening cancer.
