About Me

As an internal medicine physician specializing in cardiology, my main clinical focus is treating adults with various forms of congenital heart disease. My practice includes an emphasis on caring for patients with congenital heart disease and heart failure. In this role, I work closely with the heart failure and transplant teams here at The Ohio State University Wexner Medical Center and at Nationwide Children's Hospital. I also care for patients with acquired heart conditions such as coronary artery disease and pulmonary hypertension, and pregnant patients with heart disease.

I prioritize patient education and always take the time to ensure my patients understand their heart condition and all treatment options. I believe in shared decision-making and working collaboratively with patients to help improve their quality of life. My patients and their families can rely on me for honest communication and transparency throughout their health care journeys.

In addition to my clinical responsibilities, I am passionate about research and helping to advance the field of adult congenital heart disease and heart failure. I have written several articles published in peer-reviewed journals. I am also an assistant clinical professor of Internal Medicine in The Ohio State University College of Medicine and serve as co-leader for the Pre-clinical Cardiopulmonary Block for medical students.
