Review of Dr. Rassadi

- in Maricopa, AZ |

One of the best docs I've ever had. He is very knowledgeable and competent as well as kind and caring. I have a lot of faith in him. He has performed several procedures for me in the past and I have one pending. I would rather he do it than anyone else!

Review of Dr. Assar

- in Prescott, AZ |

Dr Assar treated my husband who had multiple system failure as a result of bacterial meningitis from a dental procedure. The infection involved endocarditis that destroyed his atrial valve. Dr Assar was candid and thorough in his explanation and immediately called in a cardiac surgeon to consult. We credit Dr Assar with being part of a team of doctors whom saved my husband’s life. During our follow ups we have not found lengthy waiting time as others have described. Perhaps he’s saving a life.

Review of Dr. Assar

Dr Assar is a great Cardiologist. He listens and tries to help you in all your health issue. He takes the time to explain things. He has done surgery on me 3 different times. I would highly recommend him to anyone.

Review of Dr. Rassadi

-AZ |

Dr Rassadi is great but communication with the staff is horrid. When they say they will call back shortly, they don’t call back. I’ve never gotten a call back after leaving a voicemail. In the afternoon all calls go directly to voicemail, but the mailbox is full, so you can’t even leave a message. They contacted the wrong insurance company for surgery approval resulting in a 3 week delay, then sent me to the wrong hospital for surgery.

Review of Dr. Assar

-AZ |

If you have plenty of time then go to see him. You always have to wait for about 2 hours. Sometimes if he could not make it back from a surgery, even if you have waited for 2 hours, they will reschedule you to come back another time. And you will have to wait for 2 hours again. He does not care about you but only his pocketbook. And he always seems so busy and can not wait to finish with you. If you ask a couple of more questions, he will become very impatient. I am not going back there.

Review of Dr. Assar

- in Casa Grande |

I was told by the ER to get in to see Dr. Assar within 2-4 days after they had him look at my EKG. I set up an appointment for 9:30 am. I went early at 9:00 am and waited. At 10:00 the front desk girl said I would be next. 2 more people came in and went back. I waited until 10:30 and asked to reschedule at a time that I would actually be seen in a decent amount of time not 2 hours after the appointment time. She then said that this is completely normal for everyday. He is always 2 or more hours.

Dr. Assar has been my doctor since 1996 and has saved me ten times. I value his judgment and expert knowledge. He is the greatest.

Review of Dr. Assar

- in Prescott, AZ |

I reside in Prescott, Arizona, Dr. Assar operated on me here at YRMC. It was emergency surgery, but I have been informed that the surgery was successful. I have no doubt I will quickly recover due to his capability which I greatly appreciate. Those within the system with whom I spoke speak highly about Dr. Assar. I thank him. Kaye M. Porter
