The reviews listed below were collected independently of Unio Specialty Care through rater8. Each review represents an authentic and verified patient experience.
Dr. Simon and her team were incredibly kind, attentive, and compassionate while caring for my mom. One thing that stood out to me was how they had a nurse available to help translate from English to Spanish whenever needed, which made such a difference in helping my mom feel comfortable and understood.
It really takes a village, and Dr. Simon’s team cares about their patients and families. My mom and I are so grateful for the level of care, patience, and professionalism they showed throughout the entire experience. Thank you, Dr. Simon and Team!

The doctor was very rude to me in the hospital disrespectful this violated my patient rights, a passionate care. I was trying to explain to her when she asked me how this all started with me choking. She was very rude, disrespectful and yelled at me.. I have been in the medical field since 1983 worked in three hospitals numerous doctors office the largest holistic center. I even have my own MASSAGE business in Pacific Palisades for many years.. I almost married three Drs was engaged and I've been a patient. A doctor should not violate a patient's right to respectful, compassionate care number one second of all you do not humiliate a patient and talk with other workers and laugh at the patient.. this happened in the operating room. You do not make a patient wait for a doctors appointment for as long as I did when I kept telling them that I was still choking that something's wrong 😑. There is more not enough space to write it..
