I'm 79 years old and have had several cardiologists in the past . None of them ever set priorities when it came to making appointments . In 1999 , I needed an implant and Westwood cardiology wanted to give me an appointment that was six weeks out ! Of course , I would have died . Thank God for Dr Seiffort who sets her priorities properly and treats her patients like human beings !!!
