Dr. Naggar is a very special doc. He listens to everything I said and commented when needed even though I have a habit of rambling on. I have many questions. He took his time and answered them in a language I could understand.

My appointmemt was rescheduoed3 or 4 times due to the Doctor havding flue. Eventually I had a vertual appointment which is less desirdable than in person. I was happy to have the appointment however because my son flu in from Chicago to help me with the appintment which would have gone for naught. I appreciated the vertual visit even though I had hoped for an inperson. The Doctor was good enough to schedule the visit while he was ill.

Dr. Naggar is very personable with great bedside manner. He has excellent communication skills. He listens closely before carefully & thoroughly assessing and evaluating a patient's condition. He clearly explains his examination procedures & thought processes. He expertly translates technical findings into layman's terms, such as explaining MRI scans. Most importantly, he is focuses on his patient throughout his entire session, dedicates ample amount of time for the visit, encourages questions to ensure patient is fully Informed of all health conditions, and works closely with the patient to develop a path forward.

I was with my wife in the hospital in an immunotherapy session and Dr. Naggar had no issue with us getting to his office late, seeing us quickly and taking his time to hear us and answer all of our questions. It was refreshing to visit a doctor that didn't rush through the visit.
