Dr. Williams is board-certified in Internal Medicine, Cardiovascular Disease, and Clinical Cardiac Electrophysiology, and is Director of Electrophysiology at Good Samaritan Hospital. He obtained his undergraduate degree with a double major in Biomedical and Electrical Engineering at Vanderbilt University. He was then awarded a Keck Fellowship for graduate school at the University of Pittsburgh where he obtained his Master’s degree in Bioengineering. He obtained his medical degree at Drexel University in Philadelphia and completed 5 years of Fellowship training in both Cardiovascular Diseases and Clinical Cardiac Electrophysiology at the university of Pittsburgh Medical Center.

His unique background and extensive knowledge of both engineering and cardiology have earned Dr. Williams many accolades within the clinical and academic settings. He’s published over 20 manuscripts and abstracts in the field of cardiology/electrophysiology and he’s received awards from both the American College of Cardiology Foundation and the National Institutes of Health. Now practicing in Lebanon, Dr. Williams offers patients advanced cardiac heart rhythm evaluation, intracardiac arrhythmia ablation (including atrial fibrillation) and implantation of pacemakers and defibrillators. The Invasive Electrophysiology Laboratory at Good Samaritan Hospital offers the most advanced 3D intracardiac mapping system and intracardiac echocardiography available and is the only center in Central PA to offer jet ventilation for advanced cardiac ablation to ensure the safest possible procedures.

He is currently involved in the PACE-MI Trial sponsored by the National Heart, Lung, and Blood Institute. As the only PACE-MI center in Pennsylvania, Dr. Williams will be enrolling patients at Good Samaritan Hospital to investigate whether pacemaker-facilitated administration of beta blockers in patients with post-MI bradycardia or heart block will improve survival.
