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.

Thyroid cancer

Doctor Klaff helped me through my thyroid cancer at age 34 male. It was a rare cancer. He called it Differentiation follicular carcinoma. I had the whole thyroid removed. It was so rare he brought it to the cancer board to see if they could find another case study. Only found one person. Anyway short story I am now 63 and appreciated his care at the time.
