Philosophy of care 

I believe in establishing a relationship with patients and families based on trust and good communication. I will be accessible and an advocate for my patients every step of the way.

Why I entered medicine

A strong interest in anatomy and physiology as well as enjoyment in caring for others is what initially led me to pursue a career in medicine. As a physician, I also find reward in the ability to discover new knowledge and therapies through research as well as teach future pediatric cardiologists. Ultimately, it is the relationships I make with patients and families and the potential to make a difference in their lives the most fulfilling.

Professional History

Dr. Callahan was born in State College, Pennsylvania and remained local as an undergraduate at Penn State University. He subsequently attended Drexel University College of Medicine for his medical degree and completed his pediatric residency and pediatric cardiology fellowship training at the Children’s Hospital of Pittsburgh. Dr. Callahan then came to Boston Children’s Hospital where he completed a senior fellowship in interventional pediatric cardiology. As staff in the invasive cardiology division, his primary interest includes transcatheter management of congenital heart disease, with a focus on pulmonary vein stenosis and the treatment of right ventricular outflow tract dysfunction. Further, he is interested in simulation and applying it to the training of cardiology fellows in the catheterization laboratory.
