He always listens,explains thoroughly,and has great sense of humor which I truly appreciate. a very caring man. I am so happy I switched to him from his associate.

Dr. Roznik is a bit more focused, and less "warm and fuzzy" than the other physicians in this group. But I like him and have gotten used to his plain or serious demeanor. I can see how other patients might prefer more warmth.

Dr. Roznik has been my physician for 20+ years. I think that says it all.

This appointment was a new patient appointment, and I am not sure if I will continue seeing this provider. I felt rushed and that he wasn't really listening to me. He also didn't seem to know any of my history, and hadn't looked at my records. I didn't leave with a good feeling about him.

Dr. seemed rushed. Didn't ask any questions beyond the initial reason for the visit.

In the main, Dr. Roznik was excellent. I got a sense that he's booked pretty tightly, but he was able to get me in to address my illness and I was more than satisfied with the care he provided.

He did not seem open to working with others outside Western Medicine to problem solve. He is a new doctor for me.... we'll see how things go.

Seemed extremely rushed. I brought up concerns at the beginning that were never addressed and I wasn't given the chance to bring them up again. After the exam, he said, let's go out and get your script, and walked out right away, which didn't give me the chance to bring up the things I needed addressed.

Doctor seemed a bit harried. Very fast talking- however, since I had a long day myself, I really just wanted to get done and out myself.

Kind, took care of my needs, took the time to call in my prescription for me, which was really nice of him.
