Dr. Baker is the first HEART DOCTOR that has ever showed any kindness and impeccable care for my condition and situation even after prescribing my medication two days later he has the head nurse called me to ask. How am I doing? I've never had anyone do this for me before and at the age of 74 with Brain Cancer Not one person and the Brain Cancer Institute has ever called me in the past 25 years to even ask anything about my health or well-being, not even once. This Dr. Baker was an answer to my prayers, and I show him true respect and honor for his gift and taking care of the most valuable organ in the human body, which is the word,, thank you, Dr. Baker immensely as long as I live, I will never forget your care and kindness

I have AFIB and had an Ablation on Dec 1, 2025 at Ascension Saint Thomas West in Nashville where Dr. Baker did this complex procedure. My experience could not have been better. Dr. Baker and all his staff were incredible did a great job. My Nurse Ellie made me feel special and was extremely helpful to me and my wife.
