John Nigro, MD

My approach to care is rooted in a deep commitment to improving the lives of children living with congenital heart disease. I believe that every child deserves a personalized path to healing, which is why I focus on developing tailored treatment plans that address each patient's unique condition, needs, and goals. With extensive experience in cardiothoracic surgery and advanced surgical expertise, I work closely with families to navigate even the most complex diagnoses with clarity and compassion. My goal is to not only improve complex heart conditions and long-term outcomes but to empower families with the knowledge and support they need throughout every step of the journey. From initial diagnosis through post-operative recovery, I am dedicated to delivering the highest standard of surgical and clinical care — combining cutting-edge techniques with a warm, family-centered approach that puts the child first, providing long term comprehensive care from prenatal through childhood to adulthood.
