Dr Kletzka is a highly skilled Cardiologist. Dr Kletzka took excellent care of my husband and now - I too have a need of a Cardilgist and asked for Dr Klerzka to help diagnose and treat my Cardiology needs. Great asset to the Froedtert Staff!!!

Dr. Klezcka is a real professional. He has cared for my cardiac needs for over a decade now, and his care for me has been consistently outstanding during those years. Quite frankly, I feel that I would not be alive and well without his care.

The doctor was quite attentive to my needs and of course I have seen him several times in the past for my annual check-up. He is very easy to talk to and always makes sure my questions are answered completely. I like him a lot and he has terrific "bed side manner". A great person to deal with. I trust him completely.
