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.

Got cancer? Doctor Mar can help.
I picked UCI medical center for its reputation as a center of excellence in cancer treatments. Doctor Mar and her colleagues have my back in my fight against cancer. They are professionals in every regard. I’m very happy with my UCI decision.

Dr. Nataliya Mar is very knowledgeable and confident in her work. She is kind, compassionate, and very patient. She takes time to listen to all your questions and concerns. Then she addresses them all explaining the treatment and encouraging you not to fear. She has been a blessing to me and my family from the time I started this journey of recovery. I thank God for her and pray that God will continue to bless her as she helps others. May God also bless her staff who selflessly work hard helping people.

ER doctor tonight refuses that i would stay overnight bc "there was no need" despite my excruciating pain during urinatio. This awesome nurse, {Staff name removed}, did recommend to the doctor that I should stay for pain management. I felt disappointed bc I was discharged past midnight without giving any regard to my illness. Soon after, I came back bc the catheter placed was leaking so much, it was already past 1A. What a horrible experience !
