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 have been coming to this office for many, many years. Dr. Bonner is fine, but the staff is always unbelievably rude, unprofessional and apparently untrained. I kept thinking things would get better, but the staff just gets worse and worse. Because I like Dr. Bonner, it is regrettable that I must now look for another Dr.

Dr. Bonner is a great doctor. However,the office staff is incompetent. After being admitted to ICU, I asked the staff to have the doctor call me due to having complications after being released from hospital. I left five messages and the dr. did not receive them. Upon a follow up appointment, the Dr.asked the office assistant to call a specialist on behave of myself. Upon not receiving a call from the spec. after three days, I called Dr. Bonners staff again at 10 am they never returned call.
