“The staff was very welcoming, I was in the waiting room for no longer that 10 minutes. The staff was very informative about everything that was being done to my child. The surprising part was that we weren't there for no more than on hour. By far the fastest cardiologist appointment I've ever gone too. I would 100% come back here for any follow up appointments, rather than our old cardiologist.”

About Dr. Joel Harnick

Dr. Joel I. Harnick, a Harvard-trained pediatric cardiologist, brings more than a decade of experience practicing on Long Island and is working to make ProHEALTH Pediatric Cardiology into the premier outpatient practice in the region, providing high-quality Pediatric Cardiology Services throughout our network and beyond. His passion for Pediatric Cardiology dates back to when he was hospitalized for an arrhythmia at 4 years old. This experience put him on the path to becoming a pediatric cardiologist so he could provide the type of comprehensive and compassionate care that he had received. So many strides have been made since then in Pediatric Cardiology and he is honored to be entrusted to address the clinical needs of his patients while also attending to the concerns of their parents.
