I sent this email to Dr. Mariana Marcu, Allergist, NYC on Jan 14, 2026. ago. She never responded. TO: Dr. Mariana Marcu "I had a Dec 5, 2025 appointment with you – 5 weeks ago. I am 77 y/o and had never seen an allergist before as I have never had serious allergies. I didn’t come to you to determine if I had allergies. I came because I have hypersensitivity pneumonitis (HP) – a progressive lung disease with no cure. I thought there might be a parallel between allergies and the cause of my HP. I have been trying to determine ... read more
Love Dr Marcu!!!, I don’t why patients are leaving bad reviews she is the most caring Dr I’ve met compared to other Drs that will literally see you for just 5 mins. Dr Marcu took her time to carefully explain my diagnosis and treatment options. I felt truly heard and never rushed during my appointment. The office staff was also professional and efficient. I highly recommend this practice to anyone seeking quality allergy and asthma care.
I get my weekly allergy shots here from Dr. Marcu, and may I say I love her and the staff so much!! For a little time reference, my first ever visit to this doctor’s office was back in 2023.

I had a terrible experience with this practice and its staff. After my doctor of 30 years retired, I scheduled an appointment with Dr. Marcu as a new patient. On my first visit, her spirometry machine was broken, meaning she couldn’t even properly assess me. When I asked when it would be fixed, she simply said, "I don’t know, it’s very expensive." She prescribed me a new steroid inhaler, which worked well, but when it came time for a renewal after six months, my pharmacy sent multiple requests with no response. When I called... read more
I have been seeing Dr. Marcu since I was 26 I am now going on 37. Dr. Marcu has such a wonderful bedside manner , never making you feel uncomfortable and always being very honest. She has always listened to my concerns , any research I found on my own and wanted to try or learn more on. She treated so many years of horrible allergies (oral and seasonal) and sever skin dermatitis. Even when insurance pushed back, she pushed forward for the course of treatment I needed! The years of flares, patchy skin, not being able to open ... read more
