Went to ER twice in one weekend with heart issue. Visited doctor and got instructions for care. HR and BP very erratic so contacted his office with concerns. Office staff took messages but never got a call from the doctor. One call was made and the next day they had no record of the call. The office staff just tells me he is very busy. This is not the response you want regarding your cardiologist.

I’ve been seeing Dr. Mahmoud Eslami for more than 10 years. He is very thorough and he is the best cardiologist. I love his staff, everyone are very friendly.

I got my leg swollen due to blood clots. It got worse, so I called the office and I saw Dr. Yalvac the following day. After taking examination of my legs, he then called the lab to do some tests the very next day. I am vey satisfied with the way he takes care of patients. He is very professional and very dedicated to his patients.

If we’re more on time would be much better. Sat in room 30 + minutes before seen this time. Prior visit sat in waiting area for almost an hour then rescheduled when informed there were still 2 people in front of me. Do like Dr. Ashtiani though or would go elsewhere.

Office, front desk and billing, are terrible. They use different phone numbers to contact patients and confirm appointments only to show up and be informed they no longer take the insurance and try to get patients to pay cash. They need to supply that information when calling to confirm the appointment. Used to be a good office. No longer. Recommend seeking out a different medical group.

my experience was very short, i have been in the hospital twice in the last month, and it takes forever to see the doctor. Both times were for afib. I had scheduled an appointment for January the fifth but had to cancel because I was in the hospital. I can’t give him any star’s because I really don’t know him

Dr Ashtiani is a great cardiologist. He’s so professional yet very down to earth with his warmth and great smile which help me to feel relaxed and hence can open up to share my symptoms easily.
