Dr. Dayaparan Nadarajah, MD

This guy is a disgusting f’ing rude a$$ piece of sh!t!!! Find someone else!!

I am surprised by some of these reviews. I have been going to this office/dr for several years. Especially through the pandemic. I have never once had issue with the dr having to keep his mask on his face and never seen it as loose fitting. Anyway, I've had great care and respect from Dr Nadarajah, always. His staff has been helpful and kind and always willing to help me with anything. Yes, it is a busy office, however, the staff helps to ease the process with their friendliness and when the Dr comes in the room he takes the time out to go over my concerns and keeps up with my health.

Patients waited in unventilated waiting room. Doctor was 55 minutes late. Doctor could not keep his loose mask from slipping beneath his nose during exam. I had to keep reminding him to pull it up.

Very good dr. For sleep apnea. Knows his business.

My husband called to make an appointment, as a new patient at their Hackettstown Office. The receptionist was rude right off that bat, short with him and told him she would call him back for an appt time. That was strange. So she didn't call back, he called the office back. They said oh yes you are schedule for this date this time, surprised he didn't know. OK, two weeks later he shows up to his appt 30 minutes early for paperwork, doors are locked. He called the office #, same rude receptionist answered, said "he is scheduled for Newton" WHAT he called the Hackettstown # and was never told to go to Newton. Needless to say- we switched Pulmonologist. When someone is sick they don't need to deal with someone like that. Extremely unprofessional, says a lot about the office, she is the front line.

terrible experience,office rude, no call back after two weeks,ins.denied test and was told Nadaraja needed to call ins. to get approval for test. The office told me he would do so and get back to me. they got back to me with "If you feel your life is in danger by the Ins. refusal go to the emergency room". REALLY The worst DR. ever

Rude, does not return calls, considers talking to patients "a waste of time" unless they have a doctor's visit he can bill out, otherwise don't waste his time.

brilliant mind with great compassion. has saved many lives from incompetent doctors.

Barely spoke to me during office visit. Didn't answer my questions. Never returned my phone calls after office visit. Have heard from others he never returns phone calls.

I have been a patient of Dr Nadarajah's for years now and I couldn't have asked for a better doctor in my wildest dreams, I asked only one thing of him keep me out of the hospital which he did amazingly, I have walked into his office time and time again with bronchitis, pneumonia, asthma issues, allergies, a sore throat so bad from my nose draining the wrong way into my lungs, black mold specks on my lungs, major back pain and Dr Nadarajah has made my life complete without even the blink of an eye he was always happy to see me and knew exactly how to handle it even when i was the one in a panic! Since i have sadly moved out of the area i miss him as my primary care doctor, I am hoping i can find another doctor as professional, down to earth, caring, and helpful as him. We need more doctors like him.
