Demetri J. Merianos, MD

I would like to sincerely thank Dr. Demetri Merianos for his professionalism and compassion. He performed surgery on my 10-year-old daughter to repair an epigastric hernia, and everything went perfectly. Dr. Merianos was very kind, attentive, and took the time to explain everything in detail before and after the procedure. His calm and caring approach made us feel supported and reassured throughout the entire process. We are deeply grateful to him and highly recommend him to anyone in need of a skilled and compassionate surgeon.

Dr. Demetri Merianos is an exceptional doctor, not only because of his high level of professionalism but also because of his genuine commitment to each of his patients. From the very first moment, his dedication and kindness make you feel like you are in the best hands. What truly sets him apart is that his care doesn’t end after surgery. He makes it clear that once he has operated on a patient, they become part of his medical family for life. He is always willing to provide support, answer questions, and offer reassurance, no matter how much time has passed. His patience, empathy, and willingness to listen make it very easy to trust him. When you’re going through a difficult time with your child’s health, finding a doctor like him—who is not only an expert in his field but also a person with a big heart—is a true relief. I would highly recommend Dr. Merianos to anyone looking for not just an exceptional surgeon but also a doctor who genuinely cares about the long-term well-being of… his patients.

He’s AMAZING. I’m the mom of a 15-year-old daughter who had a fibroadenoma removed in Nov. It was about 6 centimeters, so pretty large. My children are pretty self-sufficient, and she was able to run her own appt. I listen as she explained what she was feeling etc. I barely had to chime in. He covered it all. He made her feel so comfy. She has no problem saying she was def gonna remove it. She has a 2 pain level once she got home and only took pain meds for a day. That’s it. It looked so good even days later. The incision was CLEAN. I mean CLEAN. No black and blue marks nada. No oozing, no bleeding or discoloration. Only slept up in the living room for a few days to not lay on it. Surgery on Thursday and back to school on Monday in a soft bra, no underwire. Back to the seamless incision. He cut on the so you can’t see ANYTHING. The line is soooo thin I had to zoom in to see if he actually cut it at all. Wished he did adults. cause you see NOTHING. He told her if I was your dad I would… suggest you remove since I do these so often. Told her that may come back and just be on the look out. So at the post op appt he was super thorough and nailed everything. Always seen ASAP. Barely a wait. Just overall a super amazing experience, TRULY!

Dr. Merianos was very helpful.

We couldn’t have asked for a better doctor to perform surgery on our infant daughter to resolve a hernia. Dr. Merianos was so kind and communicative. He explained the entire process, thoroughly answered all of our questions, and made himself available for any follow ups. He truly calmed our nerves, and we are thankful that our daughter was in such good hands.

The best doctor my son could have had, an excellent surgeon. and he speaks Spanish very well.

I just wanted to write and express my gratitude for your great treatment.Please know how very deeply I appreciate your willingness to repeat the surgical procedures. You are truly exceptional in your desire to please your patients. Please accept my heartfelt thanks for all you have done for my baby. My baby had jejunal atresia and doctor Merianos did surgery for my daughter. She was premie baby 32wks. Everything went smooth and Doctor explain all details about surgery to me before and after surgery. Dr Merianos, my baby is healthy and happy thanks to you.

I met Dr. D. Merianos on Monday June 5, 2023 in his Brooklyn office at 7th Avenue. I did not wait long to see him. His staff was very cordial, friendly. We spoke for about 45 minutes and he took his time to explain to me in great details the medical procedure is going to do for my son. He also told me the pro and cons of the procedure which I did not expect him to do. After the visit, I felt that my son is in very good hands

Dr. Merianos treated my daughter. He was incredibly knowledgeable to explain the treatment necessary but also helped my daughter feel at ease. I would highly recommend him.

I’d recommend Dr. Merianos to any family/friends without hesitation. My son had his pulmonary sequestration surgery conducted by Dr. Merianos in Dec 2022 when he turned 1. Dr. Merianos was professional, courteous, patient and communicative since day one. He gave us suggestions on the best timing and approach of the procedure which was way more preferable than other opinions we got elsewhere. The surgery was very fast and successful. Dr. Merianos was responsive throughout the entire process. We are very happy with the outcome.
