I used to be with Kaiser for many years along with my children until I got to know Dr Linda Hsu's care by observing her in the medical field and getting feedback from not only her patients but also from staff in the hospitals, her colleagues and the community!!! I could not wait until it was time to enroll, and without hesitation, asked her to be my primary and my children's as well. It was the best decision I've made to know that someone truly cares about my well-being, physically, emotionally, mentally! She is a passionate woman who has so much love for mankind and dedicated to serve the community! She is a blessing!!! I also have to add that her staff in her office are very delightful and helpful!

I've called multiple times for different reasons and have left plenty of voicemails, but they…read morerarely answer their phone and never seem to call back. Days go by without any response, and I've had to go in person just to find out what's going on. It's really frustrating because a doctor's office should be accessible to their patients. I've called at different times and on different days, and it honestly feels like their phones aren't even being monitored. It shouldn't be this difficult to get in contact with your doctor's office when you need help or have questions. You should be able to get a response in a reasonable amount of time, especially when it concerns your health.

I have been a patient of Dr. Sim for approximately 30 years. I have no complaints. He is very…read moreintelligent and has always treated me with empathy and compassion. I have had several surgeries and he always orders the appropriate referrals for me. One time I needed a cardiac pre-op clearance for my surgery which was only a few days away and he then checked my insurance then got on his cell phone and called a cardiologist to personally talk with him and get me an appointment asap. Another time I had a cough which lasted for over 3months. I saw Dr. Sim and he diagnosed me and prescribed a cough medicine I had never tried before. My cough went away within 3 days. Dr Sim will always call me back with the results of my lab or X-ray results whether they are abnormal or normal. His assistant Virginia is very empathetic towards me and willing to call me back to confirm when a prescription is called in and renewed or not by my insurance. Kathy at the front desk knows my lab orders Dr Sim orders for me for my twice a year physical visits. Kathy was great when she fought for me on the phone with my insurance at the time when the insurance wanted me to find an in-network primary care physician instead of Dr Sim. She alerted my insurance at the time that I was Dr Sims patient for many years and it was my choice to switch physicians or not. I refused to switch physicians and remained a cash patient for physician visits rather than go elsewhere. Now that I am retired and will be on Medicare I plan on remaining with Dr Sim, Virginia and Kathy and their awesome service.

She did go to a specialist, but towards the end, it was Dr.Sim who took care of her needs. Every time I go to see him, I thank him for the great care he took of my mom and my dad. My mom passed away in February 2025. As things got more difficult, I appreciated that my sister or I just had to call Dr. Sim, tell him what was going on, and he would call in an appropriate medication. I also need to add that he is my trusted physician. I have several medical issues. He has guided me to the correct specialist if it is something that he feels would be better cared for in that realm. When I had something that would not go away back in 2021, he was the first to tell me my symptoms sounded like Rhumationd Arthritis. I went to a specialist for autoimmune issues. The physician, after several tests, concluded the same thing. Dr. Sim is very intelligent. I am so glad that someone like him is nearby my home. My husband sees him. My oldest son sees him. We all know we are getting the best of care with him.

Both neurology offices confirmed that providing a temporary refill is standard practice for primary care physicians in this situation. Despite this, Dr. Hsu refused to refill the prescriptions, stating it was outside her specialty--leaving her own patient without medication. We were forced to escalate through insurance and go to urgent care to obtain medications that are routinely managed in primary care. In addition, our experience with the office staff was extremely frustrating. We often encountered confusion around basic insurance and care coordination questions and had to repeatedly follow up ourselves to move things forward. This added unnecessary stress during an already difficult situation. For a vulnerable patient with dementia, this lack of continuity of care and coordination is extremely concerning and raises serious ethical concerns, as going without necessary medication places a dementia patient at risk. This experience raises serious concerns about the standard of care being provided, especially for vulnerable patients such as those with dementia, where continuity of care is critical. Due to the seriousness of this situation, we will be reporting this through appropriate regulatory channels. Patients should be aware of how situations like this may be handled. We are immediately seeking a primary care provider that ensures appropriate and consistent care moving forward.

3rd location's a charm…read more.. One of my favorite and no hassle places is Minute Clinic, and I go there whenever I need to. Unfortunately, they closed at 5:30pm, and did not take me in for the reason of my visit today even though they stop seeing patients 15 mins before and I had arrived 30 mins prior to close. Oh well. I then went to my normal Pioneer Group urgent care location in Long Beach, and they had a sign on the door stating they were CLOSED... I experienced some issues with the security officer there also... Finally, I came to the Pioneer Group Downey location... they were open!! Thank goodness. You don't know how overjoyed I was. I signed in, everything was a breeze. They called my name after about 2 mins and I was SEEN by the doctor immediately. She gave me a prescription and I am on my way to wellness. After 3 hours of driving around to see the doctor, I'm so tired but relieved of my frustration. Thank you for the rapid turnaround. I didn't expect to be seen so quickly! I hope to be well and not have to return again.

My daughter had rashes through out her body, and without even looking in her mouth (key), he diagnosed her with chicken pox. Not only that, but he prescribed a high percentage of hydrocortisone ointment to use on her face. Thankfully we refused to give her the ointment after suspicion, and took her to the ER. It turns out, with a simple look in her mouth, it ended up being HFM (hands foot mouth) disorder. And the physician there told us not to use the dangerous dose of medication Dr Venugopal prescribed. I wouldn't recommend him. Sadly, the only two decent pediatric physicians in this network are him and Dr. Kato, and both have there concerning flaws. I'd rather pick Dr. Kato, who only prescribes antibiotics used in the 80s, than mr dangerous misdiagnoses. On a side note, Dr Venugopal's nurse is nice.
