Dr Zelenka is an excellent cardiologist! He is very knowledgeable, caring, compassionate, makes time available to discuss concerns, educates you about your issues making recommendations as needed. I’ve referred several people tohim, all of whom are very pleased with his care. It is definitely worth the 50 minute drive to see him knowing we are in the best hands possible with him.
