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.

Cancelled my appointment at the last minute. In lieu of an apology, I was told they “don’t control” the online system that they chose to use to book their appointments.... I was instead offered appointments in the middle of the work day. She could be an excellent doctor, but I wouldn’t know due to the behavior of her staff.

She is quite thorough with her interview and also gives a lot of time for me to ask questions. After 2 years as my allergist I've been much less involved with the allergies that she has discovered I am sensitive to.
