Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

I had covid in March 2020 and had residual and recurring symptoms for a year. I saw at least 5 doctors and had test after test with no relief. Dr. Sagalla persistently pursued tests and treatments and diagnosed me with asthma and severe sleep apena. His treatments gave me my life back! He is the most responsive Doctor I've ever met and has given me respectful and consistent advice and care. So very grateful he is my pulmonologist!
