Excellent first visit. Very attentive to needs and very proficient in his knowledge of sleep apnea. Took 6 mos to get appointment but all in all very satisfied with visit.

This doctor is a mix. You never know what you will get on a given appointment. He is a by the book doctor, however, he can be slick to cover his butt when he has to answer to opinions he shared with others versus what he tells you. I truly admired him for a while, until he was really needed to do the right thing. He is a company man before a doctor, and for that, I had to leave as I got sicker and wasn't about to get what I needed.

DR. Katznelson has bedside manner of a toad. Know it all who does not listen to patient. Office is very impersonal and cold set up like a hospital waiting area with pagers. Seems more interested in making money then helping people get well.

This is an exceptional doctor in that he hears the patient and takes the time to listen. He is highly ethical and it shows. He spend a lot of time trying to understand problems, and is not afraid to look elsewhere to get answers. He is not ego minded, he is truly dedicated to what he does. This is an outstanding neurologist that I would highly recommend to anyone in need of one.

In my opinion, he is insensitive to patient needs. He may be a 5 star neurologist - but he lacks compassion and certainly has no bedside manner.
