Get to Know Me

Dr. Joel D. Temple is director of electrophysiology, a pediatric cardiologist, frequently invited lecturer and author of more than a dozen abstracts and journal articles. He’s a member of the American Medical Association, American College of Cardiology, Heart Rhythm Society and Pediatric Electrophysiology Society.

Why I Treat Children

I really enjoy taking part in the care of children, especially since they often can't take care of themselves, and they may have a cardiac condition through no fault of their own. It's extremely rewarding, because the care we give can last a lifetime. I enjoy the process of educating parents about how to care for their young ones. Even if they come to me upset and concerned, I try to provide them with the knowledge they need to successfully care for their child after they leave the hospital.

What I'm Passionate About

I love what I do. I enjoy working with children and families, and I enjoy working in the cardiac catheterization lab. I'm excited about the cutting-edge technology aspect of it and the fact that the technology can make a real difference for our patients. The techniques we use in the lab are very advanced and hands-on and can correct problems without the need for surgery. In fact, the field of electrophysiology (the science of diagnosing and treating the heart though electrical properties) is one of the most advanced fields in medicine right now, and it's advancing our understanding of conditions such as arrhythmias and sudden cardiac death.Outside of work, people might be interested to know that I went to college on a music scholarship and still play the trombone in local bands and orchestras.

How I Try to Make A Difference

I'm never happier than when I'm putting my medical knowledge and the technology of electrophysiology to use to correct a young patient’s situation. I try to make a difference with my approach too. I always make sure to include parents as an integral part of the care we deliver. I never want to make decisions for them, so I make sure they're a part of any decisions that need to be made. Also, I'm always honest, almost to a fault. If I don't the answer to something, I'll tell a parent. And then I'll make it my business to find the answer.
