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.

If I could give him 10 stars I would he is the most compassionate Dr. I have ever been to when I was diagnosed with cancer I literally thought my life was over but he took the ti e to talk to me and make me feel as if it was going to be OK my husband explains him as very professional but could be your best friend and my husband does not like dr.

Going through any health issues and finding the right Doctor has been difficult in California. So I'm glad Dr. Shum was recommended to me. I would have kept my cancer if I had to go back to the other doctor.

I honestly have not met a more amazing doctor. I saw him TWO times after being diagnosed and after coming from a “hot shot” Beverly Hills oncologist, Dr Shum was 5 stars! He spent so much time with us going through treatment options, pluses and minuses of each treatment method, and was patient and pleasant. Amazing bedside manner which other doctors DO NOT have. He even thinks “outside the box” which many doctors do not. I don’t have enough amazing words to describe how good I feel!

I am an ovarian cancer patient and have been with Dr Shum for about 5 years. He has been very compassionate and caring throughout my various treatments of chemo and radiation. The staff and nurses are all very kind and professional.
