I cannot say enough great things about Dr. Ali Ashtiani. As a cardiologist, he truly stands out for his depth of knowledge, attention to detail, and commitment to preventive heart care.
From the moment you walk in, you feel that you’re in the hands of someone who takes cardiovascular health seriously. Dr. Ashtiani takes the time to thoroughly review your history, risk factors, and lifestyle, and he explains everything—from cholesterol management to blood pressure and long-term heart health—in a way that is easy to understand and actionable.
What impressed me most is his proactive approach. He doesn’t just treat existing conditions—he focuses heavily on prevention, early detection, and optimizing overall heart health. Whether it’s fine-tuning medications, recommending the right tests, or giving practical lifestyle guidance, his care is thoughtful, precise, and personalized.
He is also incredibly thorough when it comes to diagnostics. You can tell he doesn’t overlook anything, which gives a strong sense of confidence and reassurance—especially when dealing with something as important as heart health.
Beyond his expertise, Dr. Ashtiani is compassionate, patient, and genuinely invested in his patients’ well-being. He takes the time to answer every question without rushing and makes sure you fully understand your treatment plan.
If you’re looking for a cardiologist who is knowledgeable, detail-oriented, and truly cares about long-term outcomes, I highly recommend Dr. Ashtiani. You will feel confident and well cared for every step of the way

Dr Eslami has been treating me for a number of years. Not only is he a very capable cardiologist but also has a kind heart and always tells me the truth. A few years back he put stents in my heart and that turned out very good. I would recommend Dr islami to anyone who has any kind of a heart problem.

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 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.
