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 did not verbally or give written consent to do an endoscopy but the doctor still shoved a long thin metal device down my nostrils. I would not recommend.

I’ve had five previous sinus surgeries which makes me a difficult patient who keeps getting sinus infections. Dr Loos is always attentive. I never get the feeling that he feels there’s nothing he can do for me. Staff is great.

I regret taking my granddaughter to see this doctor. We both felt he was anxious and impatient. He seemed irritated that we were there

When I go to a specialist, I am not seeking someone to be my friend; I want to benefit from their expertise. But expertise is not enough. If a physician is incurious as Dr. Loos is, he is likely to miss symptoms, and jump to a conclusion regarding the diagnosis that is not based upon facts. I feel like Dr. Loos is following a spreadsheet, ascribing symptoms to his disorder of choice, and fixating upon it . He treated me like I was 85 years old and feeble-minded. I am not.
