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.

Wonderful doctor and very knowledgeable in his field.

I never met in my life that unprofessional doctor. I have a lot issues with my heart and he just laughed at me. Now I am getting treatment in MGH and they found my problem. It was really important for my life. If we will have the doctors like Zimermann most of the people will just due and he will not even care. I will sue him. This person can't be a doctor

Came to the office and had to wait a while. Doctor did not see me AGAIN. Has only sent his PA in the last 2 times. Does not believe my concerns. Not happy with his service the last 5 years.
