Concerned about my heart health, but have a high degree of confidence in this doctor.

Dr. Kostopoulos is a wonderful and compassionate doctor! Thank you so much!

He is quite likely the most sincere, genuine, knowledgeable, and personable doctor I have had treat me. I wish all were just like him!

Felt safe and secure in Dr. Louie's presence. Kind, gentle and patient. He did an excellent job on all counts. This man knows his stuff. ?

Doctor is thorough, courteous and very knowledgeable.

He's a specialist so I would not expect him to respond like a PCP. He was on top of the heart issue I see him for.

excellent

Dr Kostopoulos is an outstanding physician he knows what he's talking about and he put things in simple English to understand.

I like Dr Kostopoulos he's a good heart doctor. I would recommend him.

Dr. K always takes time to explain things thoroughly and answer my questions. He is the only cardiologist who has done it so well and addressed my questions so completely. I am pleased to have him as my cardiologist.
