Dr. Arshia Noori
is board certified in Cardiac Electrophysiology and Cardiology practicing in Beverly Hills, CA. He received his undergraduate degree from UCLA and his medical degree from Chicago Medical School. He completed his post-graduate training in Internal Medicine at University of Colorado. While in training, he was also very active in innovative research in heart failure under the mentorship of physician-scientists who were involved in groundbreaking research in the use of beta-blockers as a new modality for treatment of heart failure patients. He completed his sub-specialty training in Cardiovascular Disease followed by Clinical Cardiac Electrophysiology at the University of Vermont. Cardiac Electrophysiology being a relatively young field, he had the pleasure of working with and benefiting from the experience of world-renowned individuals who were involved in the pioneering research and development of many of the tools used today for treatment of cardiac rhythm disturbances. His research involved better understanding of the molecular mechanisms involved in atrial fibrillation.
Dr. Noori’s interest and expertise are in catheter ablation for the treatment of rhythm abnormalities such as supraventricular tachycardias (SVT), atrial fibrillation and flutter as well as ventricular arrhythmias. Additionally, Dr. Noori implants devices such as pacemakers and cardiac defibrillators that help prevent sudden death from life threatening cardiac arrhythmias in individuals at risk. Additionally, he specializes in device based therapies for heart failure. Dr. Noori is a fellow of the American College of Cardiology and the Heart Rhythm Society.

Dr. Eli Simsolo
is a board-certified cardiologist and cardiac electrophysiologist practicing in Beverly Hills.
He received his Bachelor of Science from the University of California, San Diego where he graduated Magna Cum Laude and was inducted into Phi Beta Kappa. During his undergraduate studies, he volunteered at the UCSD Student-Run Free Clinic Project, helping to provide medical care to the underserved population of San Diego. After earning his Doctor of Medicine degree from Tel Aviv University, he completed his Internal Medicine Residency at the prestigious Cleveland Clinic Foundation. He had the pleasure of collaborating with numerous leaders in the field of cardiology and cardiac electrophysiology, including his mentor and former head of the Heart Rhythm Society, the late Dr. Bruce Wilkoff. Dr. Simsolo continued his extensive education with a rigorous Cardiovascular Disease Fellowship at Tufts Medical Center in Boston, the premier heart failure program of New England. He then returned to his hometown of Los Angeles to complete a Clinical Cardiac Electrophysiology Fellowship at Cedars-Sinai Medical Center.
Driven by a passion for advancing cardiovascular care, Dr. Simsolo combines his comprehensive clinical background with a notable research and publication record in leading medical journals. For instance, research he performed while in medical school on regenerative cardiac cell therapies in heart failure led to a $10 million U.S. Department of Defense grant fund. In addition to receiving numerous awards and recognitions for his teaching contributions, Dr. Simsolo is actively involved in professional organizations such as the Heart Rhythm Society and American College of Cardiology, demonstrating his commitment to staying at the forefront of his field and contributing to the broader medical community.
A teacher at heart, Dr. Simsolo takes the time to educate his patients and create a partnership to deliver personalized care to each one. His patient-centered approach is rooted in the principle that everyone’s health journey is unique and that one size does not fit all.
