Meet our strategic advisors.

Dr. Jeffrey Feiner is a general and invasive cardiologist who has been in practice for since 1982. Dr. Feiner founded and is now managing a 10 physician full services cardiology group while caring for his own patients. He is in charge of HR, contracting, IT, maintenance and vendor relationships, as well as maintaining electronic medical records system for the group. He is board certified in the American College of Cardiology and American College of Internal Medicine.

Dr. Hillis is a cardiac electrophysiologist with the Lankenau Heart Group at Bryn Mawr Hospital. His practice focuses on clinical cardiac electrophysiology and cardiac device implantation and management. He graduated from Harvard University with a degree in Biology, cum laude and received his medical degree from Columbia University P&S where he was elected to the Alpha Omega Alpha honor society. He completed his internal medicine residency at the Hospital of the University of Pennsylvania and fellowships in cardiology and cardiac electrophysiology at Thomas Jefferson University.

Philip Nimoityn, MD, FACC, is a clinical cardiologist at Cardiology Consultants of Philadelphia at Jefferson. He has a Bachelor of Science degree in Biology with Distinction from the University of the Sciences and a Doctor of Medicine degree from Sidney Kimmel Medical College at Thomas Jefferson University. His internship was at Drexel University College of Medicine/Hahnemann University Hospital, and his residency in internal medicine and fellowship in cardiovascular disease were at Thomas Jefferson University Hospital. He is a diplomate of the American Board of Internal Medicine and Subspecialty Board of Cardiovascular Disease and is a Fellow of the American College of Cardiology. He is also a member of the National Lipid Association. Dr. Nimoityn is a Clinical Assistant Professor of Medicine at Sidney Kimmel Medical College at Thomas Jefferson University and an Attending Physician at Thomas Jefferson University Hospital, where he has held numerous leadership positions including President of the Medical Staff, chair of several committees of the medical staff, member of the hospital Board of Trustees, and has been a member of the Executive Committee of the Medical Staff for 18 years. He has published in the fields of genetic disease, perioperative cardiovascular medicine, and lipid disorders. His interest in ambulatory cardiac monitoring began as a child when he assisted his father load reel-to-reel magnetic tapes into the first commercially available Holter monitor recorders soon after they were introduced. He has been actively involved with the clinical use of all generations of ambulatory cardiac monitoring and has participated in clinical trial evaluation of the technology.

Dr. Jeremy Ruskin is Professor of Medicine at Harvard Medical School and Founder and Director Emeritus of the Cardiac Arrhythmia Service and Cardiac Electrophysiology Fellowship Training Program at Massachusetts General Hospital. Dr. Ruskin received his medical degree from Harvard Medical School in 1971. He completed a residency in Internal Medicine at Beth Israel Hospital in Boston from 1971-1973. Dr. Ruskin completed a research fellowship in clinical cardiac electrophysiology at the USPHS Hospital in Staten Island, New York from 1973-75 under the mentorship of Dr. Anthony Damato, the father of modern clinical cardiac electrophysiology. He was then recruited by Dr. Edgar Haber to MGH where he completed a clinical and research fellowship in cardiovascular disease from 1975-1978 and joined the faculty in 1978.

Dr. Ruskin founded the MGH Cardiac Arrhythmia Service and Clinical Electrophysiology Laboratory in 1978, the first subspecialty service dedicated to the care of patients with cardiac arrhythmias in New England and one of the first in the US. He served as director for 38 years during which time the MGH Arrhythmia Service grew into one of the leading clinical and academic programs in the country. In 1978, Dr. Ruskin founded the MGH Fellowship Training Program in Clinical Cardiac Electrophysiology, one of the first subspecialty training programs of its type in the US. During his 40-year tenure as director of the EP training program from 1978-2018, Dr. Ruskin was responsible for the training and mentorship of more than 150 clinical and research fellows in the subspecialty of cardiac arrhythmias and electrophysiology, many of whom hold senior leadership positions at academic centers throughout the world.

Dr. Ruskin is an author of more than 500 original scientific publications, chapters, reviews, guidelines and monographs. His research has focused on mechanisms and prevention of ventricular arrhythmias and sudden cardiac death in experimental models and patients, the role of arrhythmia control devices in the prevention of sudden cardiac death, the proarrhythmic effects of cardiac and non-cardiac drugs, cardiac safety issues in new drug and device development, the use of novel biocompatible hydrogels for myocardial preservation and sustained drug delivery, brain-heart interactions in patients with cardiac arrhythmias, and new antiarrhythmic drugs and innovative technologies for catheter ablation of atrial fibrillation. Dr. Ruskin served as a member of the FDA Cardiovascular and Renal Drugs Advisory Committee for 5 years and as a consultant to the National Center for Health Services Research and Health Care Technology Assessment.

For the past 30 years, he has worked extensively on the scientific and regulatory aspects of medical device and drug development as well as cardiac safety of noncardiac drugs. He also maintains an active regional, national, and international referral practice in the field of cardiac arrhythmias and electrophysiology and is recognized annually in Best Doctors in America and Best Doctors in Boston. He teaches a year-long case-based course in principles of clinical cardiac electrophysiology and complex arrhythmias in the MGH EP fellowship program, in two courses at Harvard Medical School, and in national and international postgraduate programs. In 1995, Dr. Ruskin founded the Annual International Atrial Fibrillation Symposium which he has directed since its inception and is the largest and longest running free-standing academic meeting on atrial fibrillation worldwide, now entering its 28th year. Dr. Ruskin is the recipient of the 1997 Michel Mirowski Award for Excellence in Clinical Cardiology and Electrophysiology, the 2002 Heart Rhythm Society Pioneer in Pacing and Electrophysiology Award and the 2015 KCHRS Pioneer in Electrophysiology Award. He was named the inaugural incumbent of the Omran Alomran Endowed Chair in Cardiology at Massachusetts General Hospital in 2016. In 2017, the Jeremy Ruskin and Dan Starks Endowed Chair in Cardiology was established at MGH in recognition of Dr. Ruskin’s pioneering contributions to the field of clinical cardiac electrophysiology. In 2018, Dr. Ruskin received the William Silen Lifetime Achievement in Mentoring Award at Harvard Medical School in recognition of four decades of service to the training and career development of fellows and faculty in the field of cardiac electrophysiology. In 2022, Dr. Ruskin received the Heart Rhythm Society’s international Distinguished Teacher Award.
