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.

Intelligent and caring Doctor.
I first met Dr. Mercer as a referral from Emergency in the hospital when I couldn’t see out of one of my eyes.Dr. Mercer immediately performed surgery on my eye and I could see you again right away which I was extremely grateful for!As several years went by he was my main ophthalmologist and did a very thorough check up on my eyesight each time I visited.I highly recommend Dr. Mercer he’s a good man an experienced doctor and a very friendly person.

Confusing appointment.
My appointment was for 8:30 am, but ran late by 25 minutes. Drops that had quite a burn to them, with no warning of the sensation to come, were given by the assistant prior to the exam. The exam never included a final look, at what my vision will be like, with my new glasses, just veiwing through one eye at a time. At previous appointments with two different optomologists, I was informed I have a cataract in my left eye, believable, as I have trouble with blank spots when using the computer at work, and reading for pleasure. I now believe I need to spend more money to go get a 2nd opinion before buying new glasses.
