Dr. Mammen P Zachariah, MD

Dr. Zachariah spent a lot of time with me discussing all of my concerns, providing a roadmap and suggesting all options. I left the appointment very thankful for a chance to meet with him about my health.

Dr Zachariah is the absolute best. Very thorough and provides excellent patient care. He’s the only Cardiologist I would consider.

Dr. Zachariah was great. I was able to have full conversations with him and discuss a few options. Very comfortable to talk to and he seems to be an educator at heart in how he describes things.

I have been under Dr Zachariah's care for over 20 years, he is a very knowledgeable and caring doctor, I am very pleased with his services.

Guy is a sneaky and a liar.

In all my years of seeing doctors I have never had such a terrible experience! Dr. Zachariah did NOT listen to my concerns nor those of my primary doctor nor my pulmonologist even though their concerns were shown during a test that Dr. Mammen's wife did in his office. Instead of taking precautions and doing extra testing to ensure no problems he chose to think that his knowledge was correct. It took me 3 additional months to pay out of pocket for a test that he would not approve. That test confirmed my other doctors concerns showing additional problems and brought me to a new cardiologist who did further testing to find even more issues. I am going for yet more testing as there were additional problems found. Had I just accepted Dr. Mammen's decision who knows what could have happened! For this very reason i highly recommend NOT choosing Dr. Mammen as your cardiologist!

This man spent 5 minutes with me for a cardiac clearance for surgery and he told me that "I should consider possibly seeing a Pulmonary doctor since I snore" I asked him if he was telling me that I had to delay my surgery and he said "no I am not saying that, I am just giving you information but it is up to you" . He totally lied. He sent me with my cardiac clearance papers with no notes on it to see a pulmonary doctor and he didn't say anything to my PCP or my surgeon, what he did was put the notes to the hospital and he never told anyone, the Friday before my surgery they cancelled it because of his note. He is a liar, he delayed my surgery and had he told me that it was going to be mandatory we had time to get it done but instead he lied and took what he called my choice away from me. I am so angry with this AWFUL doctor what a coward.

Dr. Zachariah was very good to me and did great job with Cardiac Cath, diagnosis, etc. I did have a communications issue that I wanted to convey to him though, as it caused me to switch to a new Cardiologist. The situation was this...I called to get authorization for Cardiac Rehab, and the lady I spoke to, Patty, said that the requesting doctor (my surgeon) would have to request it. I then said "they told me it should come from my cardiologist, so can you Not do this", to which Patty replied, "What are we supposed to do...take up their slack?" That is NO WAY to ever speak to a patient, so I requested and was told by reception that Dr. Zachariah had been informed that I wanted to talk to him and that he'd call me. He never did; hence, I changed to a cardiologist that works in same office as my heart surgeon. I hope Dr. Zachariah will see this and address it with Patty.

This Dr. is a gift from GOD.

great doctor
