I have never met a more caring and thoughtful provider. He was absolutely phenomenal.

Dr. Brzezinski is the best. I always feel that he looks out for me and has my best interests in mind. He always takes as much time as needed to answer my questions.

Reviewed on Nov 26, 2019

The ease of scheduling my appointment is a constant occurrence. In close to 10 years that Dr. Brzezinski has been my doctor, he has ALWAYS kept his word; when he says he'll call, he calls. Dr. Brzezinski's staff, specifically his Executive Secretary is always on point, prompt in returning a phone call and or responding to my email. Having access to Dr. Brzezinski is and has NEVER been a problem nor a challenge!

Reviewed on Nov 26, 2019

Dr. Brzezinski is beyond courteous and respectful!! He is caring about me as a patient and as a person. As a patient, he explains his findings and recommendation(s) of treatment and does so without the fanfare of terminology that only a medical professional would understand. And when I don't understand something, not a problem, he will explain it again and never in a rush. Dr. Brzezinski has always remembered that my mother died of stomach cancer and when it comes to explaining findings, I trust him. I trust him so much that if his calendar is booked and I have to wait a little longer to see him, I'll choose to take the pain and discomfort and wait to see ONLY DR. BRZEZINSKI!! For close to ten years I have opted to travel to Cleveland to see Dr. Brzezinski than to be treated by some inept doctor in my area. It's Dr. Brzezinski to brought me back to health after I returned from a 3 year work assignment in the Middle East...doctors in VA/DC were playing a guessing game. I owe my health to him and the fact that he figured out what was wrong is proof that he knows what he's doing, he cares about keeping me healthy and pain free, he's honest about what he finds, he's conservative when it comes to my treatment!...he has never opted to dispensing pain medication as a treatment for me. The high degree to which he has cared for me as a patient and as a person is again why I'll stress, I'd rather take the pain and discomfort and wait to see Dr. Brzezinski but I will not agree to see any other gastro specialist. I have no reservations about recommending Dr. Brzezinski to anyone and closer to home, my siblings now know CCF and Dr. Brzezinski is who they will come to if they develop gastro issues. There is nothing in it for me to not be shy about saying Dr. Brzezinski is the best and is the only doctor I trust when it comes to my gastro health...I'm not getting special treatment or better treatment or being placed at the front of an appointment line. From my experience, Dr. Brzezinski is to gastroenterology what the late Dr. DeBakey was to the heart.

Reviewed on Nov 26, 2019

Absolutely without question or reservations that I will recommend Dr. Brzezinski, this gastro practice and CCF to others!
