Baptist Health is the best. During COVID, they made sure shots were available.
Now, post COVID, I needed an exceptional cardiologist- his name: Dr Marcus Edward St John. How do I know he is the best. That's easy- my wife, a doctor, referred me to him- he is the BEST.
Want to live longer- drive a car with the best brakes, the best airbags, etc, and always see the best doctors....the best, or nothing!

Went for a follow-up with Dr. St. John, and as always, I was called in from the waiting room right on time. The staff is consistently professional and courteous. After completing my prep session, Dr. St. John came in promptly, and we reviewed my lab results in detail. He took the time to answer all of my questions thoroughly. I truly trust Dr. St. John and feel very fortunate to have him as my cardiologist. Keep up the excellent work!

Dr. St. John explained all of test results, listened to and answered all of my questions to my satisfaction. My next appointment was scheduled. All was done in a very timely fashion. Dr. St. John and his staff are the best. With their care my heart has steadily improved. God bless them all!

I have known Dr Marcus St. John ever since he decided to join the Baptist-cardiology team. First my dad was the patient , and, now my entire family and most of my friends are under his care. His professionalism, unique dedication to his patients, knowledge and understanding of the human needs make him an extraordinary doctor. In 2017 I went under an invasive open-heart surgery , his care made a huge component on my quick recovery.I consider him a blessing to all of us. Trust him beyond believe!
