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.

Dr. Litchman was dismissive of my symptoms, and made me feel stupid for seeking help and my followup. He was not engaged, and seemed like he was reciting a speech from memory. During allergy testing, I started to feel as if I were having allergic reaction symptoms, and he told me I was just being nervous about the needles. I was not. I requested a different doctor, as I wouldn't even bother with him as a follow-up.

knowledgable but general and not client centered. I prefer doctors that learn about me and my past experiences. He probably would be fine for someone first interacting with an allergist.
