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.

From the beginning of my treatment Dr. Zumsteg has been a very clear medical professional to explain and establish treatments and goals; as well as to listen and clarify doubts and concerns.Also to a very optimistic attitude that conveys assurance,

Dr. Zumberg is a top level physician and person! He should get a raise because he provides a service that an amount of money can not match. Yes, a raise!

Dr Zumsteg is outstanding. He saved my lifeNow I know why good doctors run late. He spent so much time answering my questions. Reassuring me of all my treatments and prognosis. He's great. I've referred him other patients too and he's saved their lives also. Thank you, Cedars for having him on your staff.

Dr. Zumsteg has been my radiation oncologist since the first day I walked into Cedars-Sinai 7 years ago. He's a great doctor. He's comforting, he's reassuring and I think he's the best doctor I could've had for the treatment I needed.

My perfect score reflects the expertise of Dr. Zachary Zumsteig. Dr Zumsteig is clear, thoughtful, intelligent, and experienced. He calmly explains a pet scan so that I can understand Its results. I would recommend him to everybody who needs to go through radiation. During my six weeks, he visited with me to answer questions once per week. Because I knew I would see him, it took the stress of all my questions away. Now it's been two years of follow up, and I feel the same level of confidence and gratitude that he has decided to go into a very difficult line of medicine.

I can't express how lucky I feel to have had Dr. Zumsteg as part of my team treating an uncommon parotid cancer a few years back. He's an incredibly warm, kind person (though extremely reserved so it may not show at first) who truly had my best interests at heart and proactively communicated with my other doctors to ensure I was getting good, comprehensive care. He's genius-smart with encyclopedic knowledge, extremely well-respected by the other doctors, kind to his residents and the nurses I got to know liked him too so that says a lot. I don't think this specialty gets many reviews but I'm starting to understand how critical this physician has been to my excellent outcome from my treatment 5 years ago. Faced with a similar issue (but NOT a recurrence) now but from the wrong side of the country, I'm struggling with the idea of NOT having Dr. Z as my oncologist - I trust him that much, that I'd consider temporarily relocating to have him supervise my treatment again. HIGHLY RECOMMEND.
