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.

My wife has been a patient of Dr. Mercado for 7+ years and was very happy with his level of professionalism. because of this I switched from my old doctor to Dr Mercado about 4 years ago and I can say without hesitation that I have no regrets. His level of attentiveness is outstanding and I have never felt rushed unlike my experience with other doctors. 2 years ago he successfully determined the root cause of my 4 month cough. It was cured in about 3 days.

He saw that I was not walking straight and had poor balance. He failed to tell me to go to the ER, just kept telling me my bp was high. He seemed distracted that day when I saw him and his office was busy. I left his office unable to walk properly and as I was leaving he asked "Are you going to be ok?" My mom's doc was the one who listened to me and urged me to go to the ER. I ended having a brain infection and was in the ICU for 4 days. I won't recommend him to anyone.
