I've worked with Dr. Guzon for years, and professionally, I can say without hesitation that he is one of the most attentive, detail-focused, and compassionate physicians I've ever collaborated with. His bedside manner is exceptional, he listens deeply, and he truly pays attention to even the smallest details. Watching him care for patients over the years has always impressed me.
Then I became one of his patients -- and that experience changed my life.
When I began having symptoms, he is the reason I went to the hospital. His guidance got me there in time, and I genuinely believe he saved my life. Since then, he has helped get my blood pressure under control and worked diligently to determine why I had a heart attack at 48. His thoroughness and commitment gave me answers and stability when I needed them the most.
As a patient, he takes the time to explain everything, answer every question, and make sure I feel supported and understood. He's easy to reach, appointments are simple to schedule, and he always takes my concerns seriously.
I trust him completely -- so much that I've recommended him to the people closest to me. He now cares for my in-laws, my best friend, and even her kids. We all feel the same: Dr. Guzon is an extraordinary cardiologist and an even better human being.
If you're looking for a cardiologist who genuinely cares, pays attention, and will advocate for your health, I cannot recommend Dr. Guzon enough.

I adore Dr Guzon. He has helped me so much and is always friendly. He has also helped my son. I strongly recommend him. He will keep you well informed and help in ways you just would not expect. Wonderful bedside manner and speaks to you like a person. He also makes sure you fully understand what is being said in English terms not medical. We just love him and his staff

I believe that Dr. Osler J. Guzon saved my life. When the cardiologists at Mercy South Hospital (St. Anthony's) refused to help me, Dr. Guzon came to my rescue. He was supportive and caring and provided excellent patient care. If you read my story below, you will see why I highly recommend Dr. Guzon.
I have a history of heart disease having previously had five bypass grafts and two stents placed in the past. In January 2019, I had an additional stent placed at Mercy South and three days later had a heart attack and ended up back in the Emergency Room at Mercy South. After 11 hours in the ER and an overnight stay, the cardiologists at Mercy South told me they couldn't do any more to help me. All they offered was an increase in the prescription drugs that were already making me feel like a zombie. They gave up on me!
My family asked that I be transferred to Missouri Baptist Hospital. After being transferred, I asked Dr. Guzon, who had been highly recommended, to evaluate my situation. Dr. Guzon said he thought there were three additional opportunities to place stents in my blocked arteries. While at Missouri Baptist Hospital, Dr. Guzon's partner, Dr. Andre Bouhasin, confirmed that the stent that was put in was open and then he proceeded to fix an artery deemed 100 percent blocked and a bypass that was felt to be a futile target. I feel like a new man, and am back to normal activities.
The cardiologists at Mercy South said there were no alternatives, but Dr. Guzon stepped up with a proactive plan. He formulated that plan to get me the help I needed. Dr. Guzon is smart and talented, but he can explain medical issues in a way that the non-medical professional can understand. He is attentive and compassionate and treated me like a family member. I strongly recommend Dr. Guzon if you are in need of a cardiologist.
