"My work as a pediatric electrophysiologist involves taking care of children with heart rhythm disorders. The field of electrophysiology is so exciting because it has undergone tremendous technological advancements in the past 15 years. These advancements now allow us, in many cases, to cure heart rhythm disorders safely and in ways never before possible. It is a great example of medical technology directly impacting quality of life, and I greatly enjoy being a part of that."

Dr. Seslar is not only a brilliant doctor, he's also an excellent human being. My little guy, Charlie, was born via emergency C-section because they detected atrial flutter in him at 38 weeks. We were so fortunate to have Dr. Seslar leading the superb Children's team for his care. He listened and explained the situation, a very stressful one for a brand-new mom!, very well. He obviously not only has deep expertise in the technical side of his field, but also has the sincere empathy everyone hopes for in their doctor.

Yes, I strongly agree that Dr. Seslar is a very good listener. Some doctors forget to listen to patients, and Dr. Seslar listens to your or your kid's concerns very well. He is very dedicated to his work, and I will never forget him. If I ever end up in Seattle, I'd definitely see him again! He is also a careful doctor who knows a lot about pacemakers and other disorders. :)

If you get to chose your Pediatric Cardiologist, chose Dr. Seslar. He will go over and above your expectations and your child will love his visits. My adult son was fortunate to be one of Dr. Seslar's patients while he was working at Children's Hospital in San Diego. We both miss him very much. I give Dr. Seslar a Five+ Star rating. He is the best.
