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.

Worse office staff
I am writing this in April. I had one consultation with Dr. clerk in October which went well. Unfortunately, it’s the office staff that I am reviewing. I have called the office multiple times at least 5 trying to set up a sleep study. Each time the person that I speak to says she will call back to make an appointment. I never get an email or call back. The first two times she told me I had to fill out the forms on Elation. It was never sent to me. She had the wrong email. The second time I filled it out waiting for a call back soon after. I called back making sure she received the info. She said she did and would call back. She never did. I called back several times trying to get an appointment. no answer on the phone, I was sent to voicemail where I left several messages that were not returned. I have given up and I am now looking for anther doctor. I am sorry I never got to complete my sleep study with Dr. Clerk because of the lack of patient care by the staff.

He was thorough and also very easy to talk too. A personal doctor which always isn’t the case. Plus he’s got a sense of humor.
