Biography

As an electrophysiologist at The Ohio State University Wexner Medical Center, I specialize in the treatment of cardiac arrhythmias. My primary areas of interest include atrial fibrillation and left atrial appendage closure. I am passionate about providing treatments that can have a major impact on patient survival, well-being and quality of life. I try to understand my patients’ overarching goals and tailor treatments that are specific to their needs.

My favorite part about working at Ohio State is the unique collaboration that we have among multiple disciplines. Working at an academic medical center allows clinical care to merge with basic science and research, which ultimately benefits our patients.

When I’m not working I enjoy spending my free time traveling and sailing.
