Although Dr Luy is my GP Dr Kletzka is the Dr. in TOTAL control of my care, medications, and treatments including future procedures and planned events! My open heart surgery and aneurism plus the growth seen on my kidney will all be handled under his supervision and controls !!

provider great - nurse great!!receptionist at scheduling desk very rude
May 14, 2019
The appointment was made for a second opinion of my regular cardiologist's care who is not a Froedert doctor. It was the first time I had seen Dr Kleczka. However, if I were to find need to make a change from my regular cardiologist, I would very likely register to become one of Dr Kleczka's patients.

I really like *Dr. Kleczka a lot. He is friendly, easy going AND he keeps his appointments very timely. In fact, he never makes you wait either in the waiting room OR exam room. I can be an hour early and he will take me in. I like that. The only real issue I have with him is his unwillingness to try a different medication. I will tell him issues I may have with a certain med and he'll just says it's a good medication and there's nothing else he could give me. I'm willing to take medications, I've done so my whole life, but when certain meds causes me problems I would prefer something else. I don't want to be on something because it's a good med. if it affects my quality of life. They must be other medications out there. It can be irritating to me when I tell him some of my symptoms I'm having while on medication that I haven't had prior to taking them and then be told that it must be something else, because it's a good med.

Dr. K. always listens. He has the notes from the primary physician, comments on them, and if he feels any changes need to be made from his expertise he will make them and explain why. He is wonderful!

Wish I was young and smarter...to be a student of "Dr. Ks"! His clear understanding and ability to talk to with full understanding is...to me how all teachers and Dr.'s should be.
