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 saw Dr Zak while in the hospital. An abdominal MRI revealed cysts in my pancreas which was a complete shock to me as I have had no symptoms or gastrointestinal issues. He was abrupt, rude and totally inappropriate in addressing the possible outcomes. He presented as authoritative (listen to me, I know everything!). "If it is what I think it is you will be on chemotherapy for the rest of your life; if it is worse, you will be dead in 6 months. I reported his behavior to the nursing staff and refused to see him again. Another doctor was assigned and he is the complete opposite. Avoid Dr. Zak.

He might be a good doctor, but his office staff is a disaster, receptionist/biller Gladys is extremely rude and unprofessional, makes a lot of mistakes and ballooning your bill to a total rip-off. There is no communication with the doctor whatsoever, once you are done with a procedure, or you want to complain on his staff. Stay away from this office! There are other doctors around.
