Dr. DeFrain was my dad's surgeon. He was very compassionate and we could tell that he takes pride in his work and caring for his patients.
in St Petersburg, FL |
Dr. Defrain and his staff exuded competence and compassion from our first meeting to our last. Dr. Defrain's ability to perform coronary artery bypass surgery off-pump was a revelation to Reg and I and the speed at which Reg recovered was nothing short of miraculous. At 4 weeks after surgery Reg is pain free, walking 3 times a day, chatting with neighbors and enjoying getting back to normal. The scar on Reg's chest is healing so well he's afraid he won't get any sympathy anymore!! THANK-YOU : )

It was a very positive experience the first time I met De Defrain. He explained every thing to me and made me feel very comfortable and trusting. His office staff was very nice and friendly but professional. I feel very blessed he was recommended to.

Dr. Defrain speaks in terms that patient can understand. He makes sure that patient knows all the risks as well as what to expect after surgery. The portal makes it easy to communicate with him and his staff.
Gastonia, NC |
Defrain coerced my mother into heart surgery. After several complications and months of misery she died 5 months later. She was 89 years old and didn't deserve to die like this.
in Indian Shore, FL |
My husband was scheduled for lung cancer surgery with Dr. DeFrain. Before the operation my husband had an adverse reaction to a drug due to a positive TB test. He lost weight and developed pneumonia. Dr. DeFrain cancelled surgery and we never saw him again. Our Pulmonologist got an appointment with a colleague of Dr. DeFrain who also turned my husband down for surgery, recommending a university hospital because he could not guarantee the support we might need. We are now starting from scratch.
