Our Physicians


Dr. Greet is a Cardiac Electrophysiologist with Texas Cardiac Arrhythmia.  A native of New Jersey, he completed his medical school at New York University School of Medicine in Manhattan.  He remained there to complete his training in internal medicine and served as chief resident. He then continued his training at the Texas Heart Institute in Houston where he completed his fellowship in cardiovascular disease serving as chief cardiac fellow and sub-fellowship in cardiac electrophysiology.

He has a passion for treating those with complex arrhythmias. Dr. Greet has authored and co-authored articles in top leading journals and has been invited to present at national conferences such as the American Heart Association and Heart Rhythm Society.  Additionally, in collaboration with Rice University and Texas A&M, he has led engineering teams resulting in the development of novel medical technologies where he holds multiple patents related to these endeavors. Dr. Greet’s priority, however, is to provide the safest, most compassionate and effective treatment for those with complex arrhythmias and associated syndromes. 

Dr. Greet has a special interest in performing cardiac electrophysiologic studies and ablations without the use of potentially harmful x-rays.
