He would not care about your lab report and never follows up even if some of the the readings are alarming. You will have to rely on your own research of the numbers and then have to set up the follow up with him. Terrible.

Dr. Merola cares about his patients and that's why he spends lots of time for his patients. This triggers a very long wait in his office. Make sure that you'll bring a good book to read; then you'll be a very happy patient. He is a gem, I think.

I have been seeing Dr. Merola for all of my ailments over 25 years. I would not see another doctor for free! He is very compassionate and kind hearted. He goes above and beyond by being there for me whenever Ineed medical treatment. I couldn't ask for a better doctor. Most of the time you have to wait to see him BUT he is worth it!

Dr. Merola is nice and patient, but forget about getting a hold of him or his clinic after your visit. They do not answer emails and usually do not pick up the phone. Of course, leaving a message will take younowhere because you never hear back from them. I am deeply disappointed of someone I thought could become my primary care physician.

Horrible. Waited over an hour after my appt was scheduled. Finally got back with the doctor where h promptly answered a phone call from his wife on his cell phone and continued a chat for a few minutes. Had blood workand was supposed to go back for a follow up but it seems the office is no longer in business 2 weeks later as no one answers the phone. Oh and I still have not received tear results.

Dr. Merola was very nice to talk to and seemed to listen and pay attention when we were talking. Following up has been incredibly frustrating, however. He told me he was going to make a call to my sleep specialist laterin the day after our appointment to help me with a situation I was having. I never heard anything back - a few days later I emailed him to check in and didn't get a response back. Every single time I called the office, no matter what time of day it was, there was a prerecorded "nobody is in the office" message. Secretary was never, ever there; left messages and never got a return call or email back.

Dr Merola is definitely one of the best doctors I have ever seen. When you go with some symptoms, he knows exactly what is the issue and suggests right treatment for you. I think most of his knowledge is from hisyears of experience, which is lacking in many new generation practitioners.

Dr. Merola makes you feel like you are his only patient. He listens, assesses, explains in detail his diagnosis, the pros and cons and takes a genuine interest and concern in your well-being. I feel safe with him and trust himexplicitly. Every specialist that he has referred me to is as equally professional. Dr. Merola you can never retire. Thank you.

great bedside manner. He took the time to listen to my problem and asked detailed questions to further understand my unique situation and rule out potential causes.He had a sound multiple step path forward that included prescriptions and testingthat would provide better insight into the potential cause and solution. In addition Dr Merola explained in great depth why the test were needed and what they could reveal. He also laid out a course of action for me to follow pending the test results. His office also made sure my insurance would cover the testing before I left.

Dr M firmly believes in spending face to face time with the patient and so takes the time to explain everything. Yes that adds to the wait times but on balance it seems well worth it. Bring a book or play on your phone to pass the time.
