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.

Dr. Merlino changed the battery for my pacemaker/defibrillator and was quite the artist with a very nice, hardly noticeable scar, and no stitches!....I like Dr. Merlino and am glad he's my cardiologist...He takes the time with you in the office and doesn't rush his visits...I would definitely recommend him and his staff for their professionalism, to others

Dr. Merlino performed a cardiac ablation on my son and I can't say enough wonderful things about him. My son, is 43 and mentally challenged. Dr. Merlino spoke clearly and respectfully to him, and put my son at ease. He is often ignored while physicians speak directly to me. Not so with Dr. Merlino.
My son was given the greatest of care throughout his treatment and surgery, which was very successful. I would highly recommend him to anyone seeking cardiac care.

very good experience at the Dr. Merlino's office, Staff is very helpful, able to do the required tests need before I can see the doctor.
A very happy and good office visit.
Dr. Merlino is very easy to talk to. Does not rush his examination.
And he likes to explain every step, and he is not in a rush.
I have no hesitation in recommending Dr. Merlino to my family or friends.
