Dr. Razavi, my cardiologist of 25 years, referred me to Dr. Stephens when he retired. My wife and I are very pleased with Dr. Stephens, who is a good listener and reassuring and encouraging to both of us. I feel he will do his very best to help me with my cardiac problems. He supported my desire to return to Florida next fall and if I need to be hospitalized there, he assured me that he would be most aggressive in seeing that, if I am stabilized, he will consult with the Florida physician in charge of my case to see that I can be flown back to Cleveland Clinic as I have medical air evacuation insurance. My wife was especially reassured by that.
