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.

Inadequate care
Dr. Vierra has always been very dismissive and inattentive at all my OB appointments. So much so that I switched doctors in the middle of my pregnancy. He is always too busy to answer questions or take the time to explain conditions.

What could be improved
  • I didn't feel respected
