Dr Zahka had being seeing my son since he was born and taken to the PICU for his heart surgery. when talking to him about my son's care and during daily morning rounds in the PICU, I was completely blown away with his knowledge. I knew my son had to see him. Although all the other cardiologists in the department are fantastic, Dr Zahka is one I have full trust in with my son's condition. my son may be little but he certainly listens to him when he talks. I also admire when Dr Zahka talks to my son about his plans and what he expects from my son. Dr Zahka's fellow Dr. Steele is also fantastic! He really is extremely knowledgable just like Dr zahka and we are so comfortable with him. I really hope Dr Steele can stay with CCF because he would make a great asset to the team! My family and I are so greatful for the both of them and also so appreciative for the way they've cared for my son. Thank you!
