Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

I should sue him
Injected me with multiple antipsychotics without telling me that I did not need. He said that it was to stop my trembling, because he didn’t believe that I was trembling in pain. Denied me further scans of my abdomen. I had to come back to the ER 2 more times and was admitted and later diagnosed with stage 4 endometriosis that required emergency surgery. The antipsychotics gave me awful side effects, and the refusal of quality care made my condition worsen.

*ALWAYS TRUST YOUR YOUR GUT INSTINCT!
Here is my current, honest review based on my experience: Monday - 07/17/2023 While @ work, I randomly started experiencing body temp fluctuations from freezing cold w/ shivers, to extreme overheating, that would cause me migraines and sweat seeping through my clothes. It was so uncomfortable and embarrassing. Also, felt extreme pain on my left side. Tuesday - 07/18/2023 My health wasn't improving so I went to UCLA Urgent Care in Woodland Hls & saw Dr. Alexander Hu, who disregard & dismissed me. He didn't ask for a urine sample. Wednesday, 07/19/2023 I gta 2nd opinion @ UCLA UC in Santa Clarita & saw Dr. David Hjerpe. He ordered a urine sample, blood work, & a CT Scan. After my Scan. I wash rushed to Henry Mayo Newhall ER, where I saw Dr. Oliver Sahagun. Long story short, he expedited my results & it turned out I had a Kidney UTI & it was caught in time before I became septic!

Repair of Incarcerated hernia.
Dr. Sahagun was my ER doctor @ Henry Mayo Newhall Memorial Hospital. He was very patient with me. He took the time to explain my condition to me and did all the correct steps from the taking of an MRI prior to releasing my hernia which had become incarcerated. He advised that I stay overnight for observation which was a good call on his part because the follow up doctor made sure that I had a binder to help with the healing process and further incarceration.
What went well
  • Listened & answered questions
  • Explained conditions well
  • Staff friendliness
  • Trusted the provider's decisions
