S. Tierney, M.D.

I think it is an honor and privilege to be considered someone's doctor. I love what I do. The advances made in heart rhythm disorders in the last few years are mind-boggling. Today, we can cure fast rhythm disturbances with catheter ablations and improve quantity and quality of life with newer device therapies. I am committed to providing you a clear, simple explanation of your heart rhythm concerns and treating you the best way I can with all that modern medicine can offer... and always in a compassionate manner. We will get through this together.


Dr. Tierney graduated from the combined Siena College/Albany Medical College Program of Science, Humanities and Medicine in Albany, New York where he was one of the first students in the country to take part in a premedical program with emphasis on the humanities. It was one of the first medical education programs with a distinct focus on service to others. As part of the program, he completed medical missions at orphanages in Mexico and at the Infant Welfare Society in downtown Chicago.


After medical school, Dr. Tierney completed a combined residency in Internal Medicine and Pediatrics at Loyola University Medical Center. He then completed fellowships in Adult Cardiology and Clinical Electrophysiology, also at Loyola. He is Board Certified in Internal Medicine, Pediatrics, Cardiology and Clinical Cardiac Electrophysiology. He has served as Assistant Professor at Loyola University Medical Center where last year he was nominated Attending of the Year in the Cardiology division.


Dr. Tierney performs implantation of pacemakers, defibrillators and biventricular devices used to improve congestive heart failure. He also performs catheter ablations to help cure fast heart rhythm conditions. His research interests include applications of biventricular device therapy and prevention of sudden death. He has authored a review on catheter ablation of ventricular tachycardias and recently presented two abstracts on aspects of biventricular devices at the national Heart Rhythm Society meeting.
