My Biography & Research


As a pediatric cardiologist, I specialize in cardiac electrophysiology, which is the treatment of abnormal heart rhythms with minimally invasive interventional procedures and medications.

In my practice, I take great care in reviewing all the information regarding the child’s problem. I formulate a treatment plan that the child and family understand and can work with me to accomplish. I believe that every patient is an individual with different problems and different ways to approach these issues in their life. I try to find the best way to use my skills to help them.

I was honored to receive the first Clinical Care Achievement Award given by Cincinnati Children’s for my commitment to the care of my patients. I have dedicated my career to this, and I greatly appreciated the recognition.

In addition to my practice, I’m involved in research to develop new ways to treat heart rhythm problems with less invasive methods.

In my free time, I enjoy participating in canine agility competitions with my Cavalier King Charles spaniel, Joey. He has received his Agility Trial Championship recognition, and we have competed in the national trials.
