Dr Brzezinski is always very thorough and listens patiently. I dread the day that he retires. He is just awesome.

Dr. Brzenzinski is the most thorough and attentive doctor. He takes the time to listen and answer questions. He is definitely an expert in his field, and we are lucky to have him in our area.

Dr. B. spent over an hour and a half with me and my husband going over my history, asking questions of me, taking questions from us. Never once did we feel like he was in a hurry to get out of the room and on to his next patient. All doctors should be more like him!

I feel like the doctor is over scheduled. I had an appointment early in the morning and saw the doctor over an hour after scheduled appointment time. He is very thorough with his patients so more time should be scheduled between patients.

I appreciate the time Dr Brzezenski spends with me. I don't mind waiting when I have to because I know how well he takes care of his patients.

Dr Brzezinski seems overloaded and did not remember the specifics of my medical history, current situation, or why I had scheduled the appointment. after awhile, we had mostly cleared it up, but I have been seeing him for years, and saw him in December last, so it was surprising as he has always been on the ball. once we caught up, everything was normal.

My husband and I were so impressed by Dr. Brzezinski. He spent almost 2 hours with us going over all of my questions,concerns,and records. He truly cares for his patients and not only has an outstanding knowledge base he is caring and kind. I consider it a blessing to have seen Dr. Brzezinski.

Dr. Brzezinski is the best physician I have ever had. He takes the time to listen and to explain. He is kind and very knowledgeable about his specialty of gastroenterology. I trust him, I like him, he is fantastic.

While this has been my provider of choice for a number of years it is very difficult to get in to see him for follow up appointments even based on when he wants to see me back.

I do not mind waiting a little longer because I know the doctor will give the time needed to listen to me, be thorough, consider all options.

Dr. Brzenzski ALWAYS that's as much time with his patients as the patient requires and ALWAYS thoroughly explains all options and alternatives related to the condition being treated. I was lucky to find him as a gastroenterologist roughly 30 years ago and don't look forward to the day that relationship may end.

Dr. B was great! Would highly recommend him. My only issue was waiting the three hours from my appointment time until I saw him.

Dr. B has been my Dr for many many years, he is absolutely the greatest to me and my family. Only issue I have is I know I usually have to plan an extra few hours for any appt's. Dr B is totally worth the wait.

While things ran a little behind, it was obvious that this was only the case because Dr. Brzezinski takes ample time to connect with each patient, explain things thoroughly, and answer any questions. I'd rather wait a few minutes for the care I received than be seen right on time but be rushed through an appointment.
Reviewed on Apr 26, 2018

Dr. B is one of the best doctors I have ever seen. He takes time and is showed true concern and listened to what I had to say.
Reviewed on Jan 15, 2018
I had several questions I wanted to raise with Dr. Breziznski and could not because he spent so long scrolling through my records. This was frustrating because he did not tell me what he was even looking at and I felt he spent time on irrelevant issues which prevented me from addressing my actual concerns.

Dr. B was top notch, very kind and compassionate and I would highly recommend him to anyone.
