It would be true to say that I walked in with the heavy heart and left with much lighter one! Thank you Dr. Kassabian!

I’m very happy with the care that I have had over many years. During the pandemic he was the only one of my long term doctors that actually showed up to the hospital and saved me from unnecessary procedures prescribed by the doctor on call. I just had my annual check up and all my testing is looking good. I follow up again in 6 months because Dr. Kassabian is a very thorough.

Dr. Kassabian and his team deliver truly exceptional cardiovascular care.
The appointment was handled with impressive punctuality, resulting in virtually no wait time.
Dr. Kassabian is highly knowledgeable and takes the time to be genuinely helpful in explaining all aspects of treatment.
The entire support team was quick, professional, and consistently nice throughout the visit.
I highly recommend this practice for their efficiency, expertise, and coordinated service.
