Went for a 2nd cardiac opinion. Didn't like your too busy parking lot! But the Doctor was more than excellent--very skilled; took the time in our situation to truly evaluate husband's status; then explain it to us in layman's term. We simply LOVED him!!!! Left reassured in a difficult diagnosis that we were on the right treatment track. Bless you all!!!!!

Dr. Kostopoulos and his staff are very dedicated people, that make sure that their patients are taken care of is the best possible medical way. So that the patient knows what to do to make his/her life the best is can possibly be with their trained guidance.

Very happy with our new doctor 2nd time seeing him!

I waited 1 hour after having my blood pressure taken to enquire if I'd somehow fallen out of the queue. I was told Doc was assisting with a stress test. Doc entered 10 minutes later.

Provider wondered why we were referred to him when my father already has a cardiologist at Aurora West Allis. I told him that we were not consulted in any way, if we had been we would not have been there.

Always a pleasure to talk with Dr. Kostopoulus and his staff.

I went to this provider for maybe a second opinion. He explained to me in depth about my health condition and, I would like him to be my doctor. I don't know if Dr. Kostopoulos has an full schedule but I will recommend him to family, and friends.

Dr.Kostopoulos is the most understanding and kind

Great doctor I been seeing him for a long time

Everything was good except wait time. My appointment was at 3:45 pm and I didn't leave until 5:30 pm because of long wait time.
