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 a cancer patient of Dr. Knapp for 7 years. Thanks to his quick analysis and resulting treatment plan my cancer is undetectable. I am still on his medications and have no undesirable side effects. I also have regular scans and blood work for ensuring good health.

Compassion and kindness, what more is there?
Dr. Knapp is wonderful. I was instantly calmed by his tone and demeanor. He explained everything point blank but in a thoughtful manner. He covered everything with me and even explained possibilities that I wouldn’t have even considered. I am beyond thankful for the referral to his office.
