Dr Roznik is great.
May 15, 2017
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.

DR. Roznik is a great care provider!
March 27, 2017
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.

dr roznik is awesome.

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 Roznik was recommended by family member. Very pleased with Doctor Roznik and care my husband and I have received.

He never introduced himself despite first time I was seeing him. He took notes as I described my symptoms then hastily reeled off a series of tests that he wanted done. I asked where these were to be done & he said here in building. I only had previously had routine blood work with my primary doctor & had no idea the tests could be done right in the building.

i probably spent 15 or 20 minutes with the doctor once in my lifetime, so I can't answer definitively some questions.

Overall, the best internist I have ever had.

very positive results from both receptionist and doctor
November 17, 2016
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.
November 12, 2016
Kind, took care of my needs, took the time to call in my prescription for me, which was really nice of him.
October 24, 2016
The problem I have is bronchial and it is something I often deal with.
October 22, 2016
I have great confidence in Dr. Roznik. He takes the time to listen to the patient and he is very thorough. He puts me at ease whenever I visit him. For those reasons I decided to continue with Dr. Roznik when his office moved to Brookfield, even though I live in Oak Creek.
October 17, 2016
Dr. Roznik is the best & provides me with EXCELLENT care. I will follow him!
September 27, 2016
! thought he was sort of arrogant. He did do some tests on me and explined why he did them.
September 25, 2016
I am transferring from one state to the state of Wi. some of the questions don't fit my situation. However based on facts known to both myself and Dr Roznick ratings remain very good.
August 27, 2016
We have been with Dr. Roznik over 25 years. Feel very confirm in him.
August 13, 2016
It's a 5 minute experience where I am given a new pill everytime I go in
July 25, 2016
Provider went too fast and asked me what was wrong when he walked in. That's why I came to the doctor, for him to provide a full explanation and let me know what was exactly wrong. I feel I basically self-diagnosed myself and he just prescribed the antibiotics. Provider did not even do a full on assessment, only checked my breathing for what I think was a sinus infection.
July 18, 2016
Prescribes medication for the answer to most problems.
July 02, 2016
I am very happy with the care Dr.Roznik gave me.
June 27, 2016
Dr. Roznik took time to review my meds and health problems. He used the medical history I provided and discussed what the furute care plan would involve. GOOD JOB
May 09, 2016
Dr Roznik is always wonderful. He never makes me feel rushed and addresses any concerns immediately.
May 09, 2016
I followed this doctor from his former practice to his new practice because of how fantastic he is. You're lucky to have him on your team.
