I believe that Dr. Brzezinski is brilliant. I've suffered with my condition for many years, but since I've been seeing Dr. Brzezinski, I'm doing so much better. But beyond that, he is so thoughtful and kind. I wish all doctors were like him.

Dr. B can never retire. He is wise. He is an excellent physician. He is caring. He is soft-spoken but all-knowing. I have NEVER felt so positively about a CCF specialist. Along with my PCP -- these two physicians are why I can never even consider leaving my complex healthcare to ANY other providers. I am a Crohn's d., kidney stone pusher, and prostate cancer patient on chemo. I am blessed with Dr. B's care.

He was very patient, kind and understanding of all things discussed. We're all human and we know that some of things we do in life aren't recommended or are difficult to navigate or complicated and it was very reassuring and comforting to have a Doctor who listened and tried hard to be compassionate and understanding as opposed to criticizing or disregarding your situation and feelings. On all levels, personal, medical and emotional.

Dr. B. is an exceptional physician and person, so I'm appreciative of his time on so many levels! He is very bright, caring, and takes his time to answer all questions - which makes me a better patient; as such, everyone benefits. I am extremely lucky to have found him, and would recommend him to both family and friends! Thank you, thank you Dr. B. - as you are quite special (and my husband and I deeply trust his overview)! Not many physicians have both compassion and knowledge - so he is the "total" package, working with the patient as a unique team.

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.
