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.

Dr.Zato is great
Doctor was very empathetic as well as professional. He actually takes his time to listen to your concerns and questions. While majority of doctors just rush you out the door like they’re late for something else. Although he does spend the necessary time with his patients, the wait is actually quite short. His assistant is just as wonderful. She’s Also polite and friendly with a smile. I love being able to set up appointments via text as well. Super convenient! I definitely recommend this practice.

Genuine Doctor
My experience with Dr. Zato, is that he genuinely cares and listens to, as to what brought you to his care. I've know Dr.Zato for a long time, he was my primary care physician through my daughter's pregnancy. He always provides the best service for each individual patient.
